Antonium

Antonium is an object in Ultimate X.

Backstory
As of now, it is unknown who invented the Antonium.

Appearance
Antonium looks like Water Hazard's barnacles in Omniverse, except they have a circle shape rather than a hexagon. Infact, there were dozens of them that were invented.

Ability
Antonium harms no one else except for Xavier. But if they get on Xavier, it causes him a lot of pain, paralyzes him, the more he tries to use his powers, the more pain he will suffer, and if he doesn't get them off his body somehow in less than 5 minutes, he will eventually die. Also, when they get on Xavier, the veins on his body become visible. Antonium would still hurt Xavier even if only one gets on him.

Trivia

 * SubZero309 got the word "Antonium" comes from Marvel Comics' "Adamantium".
