One of my favourite, and definitely the most capable character thus far in Robert Kirkman's, 'The Walking Dead'.
We'll start at the beginning. In his very first speaking appearance in issue #92, Jesus takes on both Michonne and Abraham simultaneously. They have both been shown to be high tier fighters in, 'The Walking Dead'.
Jesus defeats both Michonne & Abraham unarmed:
Jesus takes on the dynamic duo and wins.
In scans 1 - 3 he effortlessly disarms Michonne, a feat not performed by anybody before or since. Bear in mind that until this point, she was essentially the combat don of the series, Kirkman had previously stated that she was the strongest character in the series. Abraham is a trained soldier and veteran, and also one of the series toughest characters.
After being briefly taken aback by Michonne in scans 4 - 5 Sgt. Abraham Ford [a proven marksman of considerable ability] fires upon him, but Jesus is capable of aim-dodging his fire and getting to cover.
In the remainder of this piece, he utilises stealth on the duo to avoid gunfire and goes on decimates the two in a brief hand to hand spar, showcasing his agility through mid-air kicks and leg sweeps.
Bear in mind that they are trying to kill him, but he does all of this while trying not to harm them at all.
Jesus vs Walkers:
Next we see him take on multiple walkers with his hands tied behind his back in issue #94.
Lots of kicks and lots of agility. While we are yet to discover just what type of training Jesus has, scans like these show he is clearly a refined combatant.
Jesus vs more walkers
In issue #103 we see Jesus tango with more walkers.
Not particularly impressive, but he demonstrates a lot of technical skill.
Jesus vs Saviors
Another display of hand to hand combat appears in issue #104. After stealthily following Dwight through Washington [a feat we'll get back to later], Jesus is set upon by John, Tara (Negan's foremost lieutenants) and an unnamed savior.
Note that on scan 1 the position Jesus is stood in, he is clearly supposed to have proficient in some relatively esoteric martial-arts.
He quickly floors John, a behemoth of a man, dodges strikes against him and is seemingly doing well in the fight, despite using only his bagpack as a weapon. Unfortunately, he is blindsided by Tara and gets taken down.
Jesus vs Negan + Saviors
Probably my favourite of Jesus' combat feats occurs in issue #114. Here we see him easily dispose of multiple foes with a combination of hand to hand and gunpower.
First of all we get to see the infamous Jesus kick.
Next, he defeats Negan. Now let's just put this into perspective, not only is Negan a man-mountain and the main antagonist of the story at this point, but he also put a beat down on the series protagonist, Rick Grimes in hand to hand combat, literally grabbing his fist out of mid air and would go on to get the better of Beta, who makes the enormous Negan look small. And let's not forget that here, Negan is surrounded by over a dozen of his own men, Jesus is fast and skilled enough to take down 3 of Negan's men and Negan himself before most people can even get their bearings. Makes you wish Jesus had been around to help in issue #100.
Jesus takes a hostage to get into the Savior base
Here, in issue #118 Rick uses Jesus as the guy to infiltrate a major savior encampment. This takes place directly after the, 'Jesus kicks an armed opponent' feat above.
Jesus is Rick's X-factor. Tough situation? Send Jesus in. He's Rick's secret weapon and here we see why, he takes this guy hostage and proceeds to defeat the first few guys inside with his gun.
Jesus takes down an armed opponent:
Next, in the midst of war, Jesus shows he is fast and skilled enough to kick a gun out of an opponents hands.
This may be less impressive if he had grabbed his wrist/gun, but the time it must have taken him to reach the gunman and perform such an elaborate move before the gunman could pull the trigger really displays his speed and agility.
Jesus vs Whisperers:
In #134 we see Jesus fighting several Whisperers and walkers simultaneously, displaying his skill and speed with his sword:
Jesus vs Whisperers 2:
Note how he is able to kick his opponent's knife into their own head and without missing a beat, throw his own knife into another opponent's head. Aside from anything else, this is just badass.
In the same issue, Jesus fights Beta, a character who seems to be around 7' tall, and has the initial advantage of surprise:
Note how Jesus was dodging Beta's attack without even looking at one point, and was only seriously pressed because he thought Aaron was going to die. Also note how surprisingly fast Beta was despite his size (later revealed to be because he was a former basketball player).
Speed and Agility:
I'm not going to go over speed (i.e. Jesus aim-dodging Abraham) or agility feats already mentioned here.
Jesus throws back a grenade:
Here we see Jesus hurl back a grenade flung over the wall of the Alexandria Safe zone in issue #120.
He was the only individual who was capable of such a feat.
Now onto displays of his agility and reflexes
Jesus catches a spear
In issue #111, Jesus easily catches a spear thrown at him by Kal and snaps it.
It is worth noting that Kal was a watchman at the Hilltop and had been shown to be proficient in the use of spears. Kal throws this within a couple of metres of Jesus and yet Jesus is still fast enough to catch it, seemingly without much issue.
Jesus' impressive leap
In issue #113, Jesus perform an impressive leap/roll, showcasing his agility.
Note how much further ahead than Aaron he is after the leap.
Jesus' other impressive leap:
Jesus is also noteworthy for his stealth abilities, shown on many occasions.
Jesus is also noteworthy for his abilities in stealth, which he has demonstrated on multiple occasions.
Scan 1 shows Jesus breaking into both the Alexandria safe zone as well as Rick's house and bedroom in #106.
Scan 2 shows Jesus has managed to sneak past the Hilltop watchmen on many occasions.
Scans 3 - 10 are from issue #103 and show him following Dwight. Negan's right hand man.
Jesus has twice shown himself to be a master escapologist, both times are shown below.
Essentially, respect Jesus. Or he'll kick your ass.
