And now, DiZo is hired by Marvel to fully retcon the clone saga and to find a way to prove that Captain America is in fact Uncle Ben's father.

You WOULD ask that one when I was away from the keyboard!!!
ARRGH!

Well, I don't look at me. I haven't yet told him he should shy away from the IM questions, considering that you know most pre-Crossing IM stuff. And what you don't know, DiZo probably does.
He needs to learn. Like I did about X Trivia and Ro-Gan.

Name the mutant Marvel hero who shares his codename with the villain in a Steve Martin western film.

I didn't know this one off the top of my head so I had to do some research...but the Mutant of which you speak is El Guapo (who was killed by his own skateboard...not THAT'S an original death in comics).

Yep, El Guapo is right! Take it away, KW...

Thanks DZ...I figure this will be an easy one...but you never know...

What is the "true identity" of New Son?

Appearing in the 1999 Gambit mini-series, Gambit is called New Son (Sun) (X-Cutioner II) in Earth-9923 reality. In his own reality, the New Sun's kinetic charging powers had flared out of control, burning the world and killing everyone. As a result, the New Sun hunted down and killed versions of himself in other realities to ensure that they would not repeat his mistakes. New Sun is not limited to inorganic matter and can convert matter into energy at a sub-molecular level so it vaporizes or explodes. He also has the ability to time travel, can propel himself by a wave-like aura and can transplant matter through time and space, as well as being able to biokinetically augment his strength, speed, endurance, and reflexes.
In this reality, New Sun was never adopted by the Thieves Guild, so his real name is not "Remy LeBeau". New Sun was raised with his full power and intended to become the fulfillment of an ancient Guild prophecy to create Heaven on Earth. However, things went wrong when he charged up his power in a special ritual -- a chain reaction was started that caused everyone on Earth beside himself to burn up. Failing to remake time, the New Sun traveled to other universes, hoping to prevent the same thing from happening there. However, he found many worlds in ruins, often because of that world’s version of Gambit. Coming to the main Marvel Universe (616), he first attempted to create a new world where everyone would eventually be transported to, using the main reality’s Gambit to help (without revealing to him who he truly was). When he learned that his plan wasn’t possible, he tried to kill Gambit, transporting both of them to his destroyed homeworld before Gambit became a threat to the main universe’s Earth world as well. During their final conflict, Gambit finally blasted the New Sun, burning out his recently increased powers, just as the New Sun died. Due to New Sun's immense power, it is speculated that New Sun was an omega-level mutant in his home dimension, and likely mutant alpha on Earth-9923; this, however, cannot be confirmed.

Excellent work VGA...(and thanks for summarizing yet another instance of where was Marvel going with this one, and who came up with THAT idea anyway)

The thread is yours...

Thank you sir. My question:

Which of Iron Man's villains reformed and ended up working for Stark Industries?

It's an interesting question you pose...I can think of two IM villains who were Stark employees...Backlash/Blacklash and Jackfrost/Blizzard...however you asked for reformed...

I remember Scott Lang (who later became Ant Man) a reformed ex-con who also worker for Stark...but I'm not sure if that's who you are thinking of...

I think he means Clayton Wilson/Force, later went by the name "Carl Walker". He was a key part of the "Armor Wars" storyline.

Good call JTR...I think you are correct here.

I, too, think you're thinking of Force. Although, there was a third Blizzard in a one-shot Iron Man story in the 1990s Marvel Super-Heroes comic who would also fit that bill. (Can't remember his real name; I think he was supposed to be Donald Gill's brother or cousin or something.)

And didn't the Wraith end up working for SI during that Midas storyline, too?

And for a short time, I think the Living Laser held a job for Stark Enterprises, when Rhodey was War Machine and Tony was in stasis and thought dead.
That's the thing tho, there have been several "Stark" companies. A bit tricky to remember who worked at which. The question involved "Stark Industries"tark International, Stark Enterprises, Stark/Fujikawa and Stark Solutions and I have no idea what it's called these days.
