World War Hulk
Tom was next seen during the event known as World War Hulk, where encountered the heroes Hercules, Angel, Namora and Amadeus Cho. These four heroes wanted to help the Hulk, feeling he had been treated poorly by the heroes he fought with. Tom followed them for a brief period, witnessing the Hulk beating Hercules as he tried to tell his old friend they wanted to help. Tom went on to testify on the side of the Hulk, during the gladiatorial battles, where the Hulk pitted the Illuminati against each other.
At the end of the War, Tom was caught up in the aftermath, infiltrating his way into the labs of the Avengers Mansion, and using a third generation particle accelerator to finally perfect the Pym Particle serum, allowing him to grow to a huge size. Siding with the refugees from Planet Skaar, he attacked Iron Man. Iron Man made short work of Tom, untrained as he was, and set off to complete his mission. It was at this point Tom witnessed the two factions of aliens, the Red Skinned people of Skaar and the Insectoids, battling against each other. He tried to prevent them from killing each other, but ended up being hurt by their advanced weaponry. It wasn't until Elloe, made them all warbound by impaling herself on both of their weapons, that the fighting stopped.
Tom, ashamed by his actions brought the dead to Tony Stark before turning his attention to rebuilding the City. Tom then tried to join Damage Control, and after some initial difficulties, he was allowed to join. Along with many other heroes, he assisted in rebuilding the city, along with battling the Thunderbolts, and calming a now sentient Chrysler Building.
Black Goliath recently joined Wonder Man's team, the Revengers. Wonder Man came to the notion that the Avengers cause more harm than good, thus he put together a team to take the Avengers out of commission. They successfully invaded Avenger's Mansion and defeated them. However, the Avengers retaliated and defeated the Revengers.
War of the Realms
When Malekith leads an army made up of soldiers from all the different realms to take Midgard, Freya rallies the heroes of Earth to fight back. The Frost Giants are able to take over Florida, so Freya enlists Tom for a group of Giant Men (the new Giant Man, Atlas, and leader Scott Lang) into enemy territory, disguised as Frost Giants, and defeat Ymir, the father of the Frost Giants. Tom joins even though he is insecure about having the weakest size powers.
It turns out Moonstone had enslaved a number of Florida women into handmaidens so she could torture and take advantage of Ymir. They have been carving pieces off his frozen body to create new Frost Giants in exchange for being left alone in the new world order. Just then one of the handmaidens reveals herself to be Cassie in her Stinger gear ready to liberate the rest of the slaves.
Together, they convince Moonstone to end her madness, but as they discus how to finish off Ymir, Raz makes an executive decision to let him go. He was a victim of Moonstone and left the realm without argument.
