Bulldozer (alongside his fellow Wrecking Crew members) appears in Marvel: Ultimate Alliance
Henry Camp was born in Topeka, Kansas. He was a Master Sergeant in the United States Army before being dishonorably discharged. Soon after he entered a life of crime and was later caught and sent to Ryker's Island Prison. He then became cellmates with Dirk Garthwaite, also known as The Wrecker.
Garthwaite, together with Camp and two other inmates at Ryker's Island Prison, Dr. Eliot Franklin, and Brian Phillip Calusky, made a successful jailbreak and managed to locate his crowbar. Willing to share his power with his allies, The Wrecker had the three other convicts join him in holding onto the crowbar outside during an electrical storm. Lightning struck the crowbar, magically distributing the enchanted strength bestowed upon The Wrecker among the four of them. The Wrecker's three allies then adopted costumes and aliases as well: Franklin became Thunderball, Calusky became Piledriver, and Henry Camp became Bulldozer, constructing a special metal helmet for the occasion. Together the four superhumanly strong criminals became known as The Wrecking Crew, who were led by The Wrecker himself. The Wrecking Crew broke out of prison and battled the Defenders while attempting to locate the Gamma Bomb.
With the Wrecking Crew, Bulldozer next battled Captain America and Iron Fist while trying to lure Thor into battle. The Wrecking Crew then did battle, Thor. The Wrecking Crew were among the various criminals taken to the Beyonder's Battleworld, including a number of super-powered criminals and superheroes. Bulldozer got the opportunity to face off against the Avengers, X-Men, Fantastic Four, and other superheroes. However, he and the rest of the Crew were soundly outmatched by the She-Hulk on one occasion. The Wrecking Crew next battled Spider-Man and Spider-Woman II. Along with the Wrecking Crew, Bulldozer next joined the fourth Masters of Evil, which attacked and took over Avengers Mansion. Bulldozer helped defeat the god Hercules in combat but was drained of his superhuman powers by Thor. He was freed from prison by the Wrecker, but without his superhuman powers, he was defeated by Spider-Man and Spider-Woman. With the Wrecking Crew, Camp freed the Wrecker and Ulik from prison from police custody. He regained his powers and battled Hercules, Thor, Excalibur, Code: Blue, and Ghost Rider. His powers were then again drained by Loki
