Erik Magnus Lehnsherr, Max Eisenhardt, Eric Magnus/Magneto
A four-fingered slave, created by the Mojoverse to be a TV star. Supposedly the hero who would free the Mojoverse from its tyrannical despot, he's had some trouble with that over the years. First appearing as a naive, lucky fool (and in a love triangle against his will with Rogue and Dazzler), then becoming a less naive, not quite as lucky, hero. Friends of his tend to end up in the worst way: Ricochet Rita was turned into Spiral, Dazzler miscarried their child. It's worth noting that he was the second non-mutant to join the team.
A Cheyenne Indian, born to be a shaman. He ran from his responsibilities and joined the military, only to conjure up some badassery in Vietnam and releasing the Trickster. Then he worked for the US government as their gadget man, only to create the gun that stripped Storm (accidentally: it was meant to be Rogue) of her powers. He nursed her back to health, then got a What the Hell, Hero? for it when she found out he was at fault. Sacrificed the X-Men (at the time) with their permission to lock away the entity he had released, after it wreaked havoc in Dallas. He eventually joined the X-Men and wanted to marry Storm, but ultimately left her (and the team) for Mystique when he felt Ororo didn't love him. You can imagine how well that relationship went, and he regretted his actions when Storm went on to marry the Black Panther. It is theorized he'll become the founder of the X.U.E. (Xavier's Underground Enforcers) in Bishop's future.
- Anti-Hero: Originally usually presented as mixed traits from type II and IV, but debatable as he technically started out as a weapon-dealing, ex-Vietnam war criminal, so Warren Ellis probably had a good point in interpreting him as type V or a Designated Hero Villain Protagonist.
- Artificial Limbs: His right hand and leg are cybernetic.
- The Atoner: He joined the X-Men to make up for making a superhuman-depowering gun. And also in the hope of getting into Storm's pants.
- Ditzy Genius: In X-Men Evolution and Wolverine and the X-Men cartoon.
- Felony Misdemeanor: Storm fans hated Forge for breaking up with her just as she was going to accept his proposal, leaving her for Mystique. Debate over who was wrong for the break up can get intense, but the two ex-lovers eventually met up and agreed that both were at fault to some extent.
- Florence Nightingale Effect: Storm first, then Mystique.
- Gadgeteer Genius: Takes this Up to Eleven
- Literal Disarming: He had his bionic hand (and leg) removed by Cameron Hodge during the X-Tinction Agenda crossover to make him less dangerous. It was also twisted payback for deliberately putting himself in stasis so nobody could find the X-Men's plan by scanning his mind.
- Magical Native American: Doesn't come up very often.
- Mr. Fixit: His mutant ability helps him build machines by simply imagining what they should do, rather than working out the pesky details.
- Older Than They Look: Since his origin is still entrenched in Vietnam with no Retcon yet to update him to a more current war for his backstory, he's fallen into this trope. By now, he's have to be in his early 60s at the least to have served in the Vietnam War,
- Only Known by Their Nickname: His real name is not revealed.
- Techno Wizard: A classic example.
- Totally Radical: In X-Men Evolution cartoon. Made rather funny because he actually looked a LOT like Fez from That '70s Show...
