Scorpion 2099

Scorpion 2099 is a villain from the alternate future of Marvel 2099, and an enemy of Spider-Man 2099. He is a different version of the mainstream Scorpion, and is a completely different person with somewhat different powers.

Spider-Man: Shattered Dimensions
Scorpion 2099 was most prominently featured in the video game, Spider-Man: Shattered Dimensions and was the main boss on the second 2099 level. He was originally Kron Stone, the cruel and spoiled son of Alchemex's leader. In a freak accident involving the splicing and combining of DNA in Alchemex's labs, Kron was transformed into a huge, hideous monster that was part-human and mostly-scorpion. Enraged and confused at his gruesome mutation, Kron wrecked havoc in Nuevo York City, until Spider-Man 2099 arrived to stop him. Kron, like all of the other game bosses, had gotten a hold of a piece of the Tablet of Order and Chaos, and used it's power to create hundreds of miniature versions of himself as minions, via acidic eggs. Spider-Man finally beats him by throwing acid eggs at the ceiling, causing it to collapse on top of Scorpion.

Scorpion 2099 had great superhuman strength and a thick, scaly armored skin. His right arm was mutated into a huge scorpion-like pincher, and he had a long tail that he could shoot acid out of.
