Well, at least we know changing his name wasn’t hard for him. Introduced in Avengers #21 (1965) by Stan Lee, Jack Kirby and Don Heck, Erik Josten ran away to join the army after his sister death, blaming himself for it, but would be caught smuggling and fled the army to become a mercenary. He would begin working for Baron Zemo (Heinrich) and would help the villain gain the equipment to create the Ionic Ray that Zemo would use to create Wonder Man. When Zemo fled South Africa and having been wound by African authorities, Josten sought refuge in the base. He would encounter Enchantress and she used the machine to give him powers similar to Wonder Man. Smitten by Enchantress, he would take the name Power man and help her in a scheme to discredit the Avengers. When that failed and she abandoned him, he was arrested but the Avenger refused to charge him as they believed he was controlled by Enchantress. He would later team up with Swordsman and Black Widow against the Avengers before eventually joining Grim Reaper’s Lethal Legion and later sent to prison.

He was later released and learnt that Luke Cage had taken the name Power Man. They fought for the rights of the name and lost. He would take the name Smuggler soon after and later began working for Count Nefaria, who would later steal his powers to use against the Avengers. He would later battle Spider-man before being sent to prison again. Upon his release, he sought out Karl Malus who used Pym Particles to give Josten the power to grow into giant size. Taking the name Goliath, he would battle the WCA, who barely defeated him. He would later be freed by Grim Reaper and battled the WCA again before stalking Wonder Man, believing her could get more power from him. He would fight for the right to the name Goliath after Hawkeye took the name for himself. He was later kidnapped and tortured by Kosmos, only to be freed by Baron Zemo (Helmut) who was forming a new Masters of Evil. Fixer would purge him of the Pym Particles but his Ionic powers would allow him to grow and shrinking.

Grateful to Zemo, he would join his team as they became the Thunderbolts, taking the name Atlas. Appearing as heroes, he would later began a close friendship with Dallas Riordan but when Zemo’s revealed his true plan, she rejected him. Along with the rest of the team when they realised they prefer being heros, Atlas would betray Zemo and the T-Bolts would work under Hawkeye to become true heroes. He was later kidnapped and controlled by Neferia alongside Wonder Man, in Neferia’s war against his daughter Madame Masque. He was later believed killed by Scourge (Nomad) but would later reform sharing his Dallas’ body for a while. They would return to the T-Bolts before being shunted to Counter-Earth and being led by Zemo again, eventually separating from Dallas. They would eventually return to Earth and would follow Zemo again in the T-Bolts until his plan was revealed again. The T-bolts would break up until the Avengers disbanded and he was recruited by Mach-3.

After leaving the T-Bolts, he would join the Defenders, Wonder Man’s Revengers, before he was taken to Pleasant Hill prison. He would later aid Zemo in the mass breakout but would not fight the Avengers. He was teleport away by Winter Soldier with Kobik’s power, in order to protect the young Cosmic Cube. He was later approached by Zemo to rejoin the Masters but he refused and was attacked by Zemo and his team. He was saved by Jolt but was defeated and the T-Bolts captured. He would later defect to the Masters and force Kobik to send Winter Soldier back into the past shattering Kobik. He would join the Masters and later the Army of Evil in the search of Kobik and the Hydra takeover of America. He would be place in statis but was later freed.
