The Peak Serum (Now Obsolete)
(taken from Anthony_Stark's Powers and Abilities section - http://www.comicvine.com/profile/anthony_stark/about-me/)
(specific information regarding Jacob highlighted in bold)
The effects are that now the inner layers of the Peak suit can be stored in the hollows of his bones, and he can control the suit with his mind through direct brain impulses and the Horizon implants. He can also remotely connect to just about any communication device, including satellites and computers, across the world. Stark can even regenerate organs due to the enhancement but this takes sometimes weeks, or simply days depending on his current state.
Due to the magnified dosage of the Peak serum used to revive Jacob, his regenerative capabilities are much faster than his older brother. Unfortunately, this takes little bites out of his stamina, but this is countered by the infinitely powered arc reactor in his chest, a device installed by Anthony Stark to keep his little brother's heart active.
The Peak serum also allows Stark to interface with his armour in a faster and more efficient manner compared to the Pre-Peak Serum, thus dramatically increasing his response time to enemies that fight at super-human speeds. Because of his unique Peak serum, he is shielded from EMP as he can coat his body in a full metal casing, creating a shielding.
Using the suit this way, he can coat his body in a layer of simple metal that is heat resistant, EMP, Radiation absorbing to an extent and even magnetically not active, so people who control metal cannot move his body. Obviously, this allows him to take punches fairly easily compare the average human as they would be punching metal. But any harder punch will and has hurt him, but the Serum acts like a healing factor, But not an instant healing factor. He CAN be scarred if the attack is powerful enough and/or his body is already under immense pressure so the healing factor ignores to repair it fully and make him look like before.
Peak Human Abilities because of Serum
The Serum has effectively made his bone structure stronger than the average human ( And some super-humans ) , he can take impacts that would shatter normal humans bones with ease but some discomfort, this is further helped as if he DOES get injured, the metal inside his body can repair his broken bones or make a temporary bone structure to stop him dying during a battle then after the battle he can repair.
This Serum has further helped as it has given his entire body a boost, meaning he can naturally run and perform feats of speed at above peak human strength, his reflexes are now even higher as the Summit implant into his brain gives him computer speed reflexes, however his physical body does not manifest these speeds without the suit.
He can now lift just under half a ton without the suit, and punch at the same strength of the lifting, this is because his cells and bone/muscle structure has been improved heavily because of the Serum, allowing him to perform feats of strength that are incredible, his endurance and stamina have become enhanced so he rarely gets tired.
(taken from Anthony_Stark's bio with minor changing done to relate to Assault - link to source above)
Assault's abilities are constantly changing because of his brother, Peak, the original iron crusader's constant technological upgrades on the armours. In general terms, he has super strength due to his suits. The exact amount of strength is unknown, but it seems that he can lift and press over 100 tons.
The armour is very durable, capable of withstanding tremendous amounts of punishment. The Peak armour has a muscularly aligned matrix of crystallized iron enhanced by magnetic fields over layers of other metals like titanium, which grants him endurance capable of withstanding high calibre bullets with ease. He can withstand rockets, torpedoes and such, although he does take damage. The armour also enables Assault to fly at high speeds, exceeding the speed of a jet air plane, due to the rocket propelled boots that are placed on the bottom of the armour's boots.
Assault's suit has many power sources, such as solar converters, electrical batteries and an on-board generator that uses beta particle absorption as a fuel source. The suit is also able to convert nearby energy sources, such as heat or kinetic energy into electricity, or even drain electrical energy directly into the batteries for recharge. Although the suit has some open holes to allow the wearer to breathe normal air, it can be sealed off, allowing the pilot of the suit to go underwater or into space by granting its own life support and limited air supply systems.
While the Peaks suit is very durable, high amounts of lighting or electricity can make the suit overload, as well as magnets, as this would happen to a regular machine.
This may also have especially serious affects on Jacob's arc reactor, which might even malfunction as a result. But he would only be affected so fatally if he were not wearing his under sheath.
Arc Reactor Suit Implant
He has always had trouble making his suit run on conventional batteries, so he decided to invent something that would prove to be one of his most prized possessions, this reactor, a little like a small version of a particle accelerator uses the energy used by high speed particles spinning around to create a near infinite amount of energy, It allows his suits hundreds of hours of "battery" time, and once this runs out. He can use the re-charging abilities his suit has.
Jacob has the arc reactor installed within his chest, his suit of armour simply uses energy off of it instead of another reactor within the armour.
However, once the suit is out of batteries or power, he can only use it for a over expensive suit of Armour without any functions apart from emergency power with Summit to talk too.
Jacob carries a spare, inactive arc reactor in the suit should his ever run out - which would result in cardiac arrest and possible death.
Horizon (Peak's AI) & Summit (Assault's AI)
Horizon is the AI that has been implanted into Peak's brain, and Summit is the AI implanted within his younger brother, Assault's brain. This allows him a 24/7 view of the world through satellites and other means, he has a constant HUD that can help him. This implant lets him work at computer speed mentally without the suit, but with it his body can function at those speeds as it has the capacity. Horizon and Summit have it's own personalities, and continually condescend the Stark while helping them, It gives them updates constantly on how the suit and his own body is doing, working out the best possible things to do in a situation. It can manually hack things, without Stark having to get involved.
Some people may see Summit as a simple AI, and AI that can do things that are wondrous however this would be wrong. Summit was maybe not the strongest or most technologically advanced AI on the planet, however it contained something inside of its processing units and integration into Starks mind, body and suit to achieve the up-most connection between the two, whatever Summit thought independently to Jake and Vice versa whatever Jake thought would instantly, without a delay be routed to each-others processing units. In this case Starks brain and on the other hand Summit's actual processing unit that rivalled and even exceeded the brain in some aspects.
One of Horizons inherent things that made it so awe-inspiring was the fact it worked so efficiently and with unparalleled dignity it would seem almost like a precognitive ability Stark had because of the way Summit analysed everything that was happening around Stark, this was the reason why his brother was able to defend against the assassinations on the roof of Peak tower without any warning of multiple attackers from his own brain, Horizon without Stark realizing had made him aware of a threat and interdependently changed the way in which he perceived the attack. Both Starks had faith in the AI's ability to not abuse this power, and it had turned out well.
The Assault Suit (Now Obsolete)
(taken from Anthony_Stark's bio - "Annihilator Suit - Mark Three" - link above)
This suit is more than an upgrade from the Peak model, it's an entirely new model. Unlike the Peak model, in which the suits underlining is stored in the hollows of Jacob's bones, this suit in it's entirety is stored within Stark's body, activating with a single thought.
Now composed of hyper thought sensitive nano-bots designed to respond only to Jacob's brain patterns, they can loosely weave together to mimic clothing, or compact themselves together to become as dense and strong as steel. Also, this armour does not rely on gears or servos for mobility, this armour acts as a second layer of artificial muscle, making it extremely lightweight and versatile.
It also appears the nano-bots can bind together to form working machines and enable energy output, such as the repulsor rays, and thrusters. Overall, this suit is the most hi-tech model built by Tony Stark to date, out performing his previous models.
It can resist any rise in temperature and can output high amounts of heat to defend oneself. It can re-charge itself from the sun so this means it has nearly limit-less power.
This sleek red and yellow suit (composed of impact resistant carbon-composites overlaid on top of layered "flex-metal" which can condense itself like a 3-dimensional accordion pleat) was a polarized metal mesh armour that uses every bit of space for detection and evasion components. Most of this armour used solar power to charge the batteries and run most of the integrated circuitry, though the pods on the sides were batteries that could maintain the suit's functions for a short time.
It was able to recharge itself from electrical sources, a thermocouple to siphon power from extreme heat or cold, and solar power. The suit utilized force field technology to render Assault electronically invisible- a layer of low density plasma would be held in place by a focused magnetic field, and the tripole waveform reflected radar, along with a wave modifier that bent the radar around it. To quash any detectable infra-red signature, the armour's boot-jet exhaust was "washed" by bursts of super-cooled air. The micro-turbines on his jet boots possess assisted air liquification devices, rings of liquid oxygen jets, that cool the boots' emissions.
Repulsors : Laser-guided particle beam emission units mounted in the palm of each hand.
Unibeam: Multi-band light and force beam emitter. Can be adjusted for a variety of effects such as searchlight, heat ray, tractor beam, laser, image inducer and broad-spectrum (UV to Infra-red) light beam.
Pulse Bolt Generators: Plasma discharges that build in intensity as they travel through the atmosphere, picking up static and ambient energy, for a more powerful effect than the repulsors.
Force Shield: A focused photon emitter on the back of his left wrist that shapes into a shield.
Electromagnetic Pulse: knocks out electrical systems within range, including those of the armour itself, which reboots after six minutes.
Double-barreled cannon (wrist-mounted): Wrist-mounted, fires various ammo types. Ammo is user-selectable and is fed from belt circling the upper wrist.
Flamethrower (wrist-mounted): Largely ineffective while in-flight, but highly effective on "cleaning up" after fighting.
Laser Blade (wrist-mounted) : Able to cut through nearly any metal, by melting it. Deadly to human flesh.
Mini gun (shoulder-mounted pop-out): Shoulder-mounted and using an electronic firing system. This is a state-of-the-art Gatling-type machine gun firing case-less ammunition. It can be loaded with a wide array of various bullet types including stun and armour-piercing. Default load out is 10000 rounds of depleted uranium bullets which are fired electrically, minimizing moving parts.
Micro-Rocket Pack (shoulder-mounted): Similar to an assault helicopter rocket pack, holds a variety of up to 15 rockets, including High Explosive, Concussion, Smoke, Flare, and Miniature Nuclear. Can track up to 15 targets at once, Fires a depleted Uranium Round or other things.
Particle Beam Discharger (Inside palm): also called plasma cannon.
Single barrel missile launcher (shoulder-mounted): similar to a man-portable missile launcher, this weapon holds only a single shot.
Gas filters - Can filter out any gas that is intended to harm.
Foot stabilizers - If a high wind or current attempts to-pick himself up, He can magnetize his feet to the ground, or spikes come out and implant them-self into the floor.
Teleporter - This is a massive power-drain but can be done in if needed.
Short-Range Projections - Able to make a 3D realistic hologram to distract enemies or for other fun uses.
Flares - Against missiles , Stored in his arms, and legs.
Self Destruct - As a last resort, if activated the core in the suit will create a nuclear blast
Magnetic Force-Field - The suit creates a force-field which can be modified at will by its user by incrementing the power of the Reactor. It can be so powerful to destroy bullets or repel people.
Psi-Shields - The suit has a built in Anti-Illusion/Mind Infiltration facilities, This works by creating a complex series of "fake" brains that can trick foes who are trying to infiltrate his mind. This further helps with Summit, Being an AI can temporarily control his mind, or tell him if somebody is attempting to make an illusion, or even control the suit while it sedates Jacob to prevent a disaster.
Override: When required, This new Suit can amplify, including strength amplification, durability amplification, and repulsor intensity can be greatly increased, by bypassing safety circuits and limiters. However, there is a chance that this can result in a complete system failure of the armour. The range of the Override can be controlled as only reaching his very limit and staying at it for a long time will cause a system failure.
Omnibeam: Only this suit has this function yet, It is an overcharged Unibeam - the Omnibeam can generate heats at 25232 degrees Fahrenheit, extremely powerful lights causing irreversible blindness in the enemy, and emit ultrasonic attacks capable of stunning even superhumanly durable foes and even causing disintegration.
Defensive modes: Camouflage mode allowed Peak to blend into his surroundings while a stealth mode rendered him invisible to others’ sensors.
Magnetism field - Able to cast 4 metal spheres into the air during a battle, and control the magnetic fields within.
