I am a child of the 80s and 90s. I lived through the "dark ages" of comics and y'know what? I love it for being so awesomely terrible. let me introduce to one of my favorite characters, and I mean that with complete unironic conviction:
Behold: Adam-X: The EXTREME.
So if wasn't already painfully obvious, Adam-X THE EXTREME was a product of the 90s. A human-Shi'ar hybrid, he appeared a few times in Marvel over the years, mostly in X-men and X-Force. Adam-X was a skilled hand to hand combatant whose superpower was the ability to BOIL THE BLOOD of his enemies-- but only if they had an open wound, hence is why he looks like he raided The Shredder's closet.
Like all new franchise characters, Marvel tried their damndest to push this character. He was in a a couple of their X-men trading card sets, hell he even had an action figure. At one time, he was also supposed to be the third forgotten Summers brother, making him brother to both Cyclops and Havok. But alas, Marvel's editorial department reneged on that idea and by the end of the 90s, Adam-X THE EXTREME has fallen into obscurity, with only a couple of gag appearances since.
EXTREEEEEEEEME.
