Major Story Arcs
Unicorn was among the villains who traveled to the Baxter Building (under the influence of Doctor Doom’s emotion charger) to confront the Fantastic Four during Sue Storm and Reed Richard’s wedding party. He later made a team with Beetle, Electro, the Mandarin, and the Melter to attack Cyclops and Iceman, but when they all fired energy blasts at their opponents, the collateral damage knocked them all out instead of their foes.
Unicorn later allies with Count Nefaria because he needs money, and attacks Washington D.C. along with Count Nefaria and several other villains. He manages to capture Cyclops with the help of Eel, but is later stopped by a group of X-Men.
Attempting to become powerful enough to defeat Iron Man, Unicorn undergoes an experiment to augment his strength. After this, he battles Iron Man again but is once again defeated. The experiment leaves Unicorn with cellular deterioration, which he attempts to cure by allying with Red Ghost, who claims to have the cure. Soon, Unicorn discovers that Red Ghost was lying, and he does not, in fact, have the cure. After this, Unicorn allies with Iron Man against Red Ghost to defeat him and escape.
Mandarin makes the same claim to Unicorn, that he has the cure, and Unicorn fights Iron Man for the cure. Unicorn fights Iron Man twice but is defeated both times. Interestingly enough, after Unicorn and Iron Man’s first battle, Mandarin’s consciousness is somehow trapped inside Unicorn’s body, but later freed.
Titanium Man, pretending to be somebody called ‘The Other’, later uses Unicorn to fight Iron Man again, however Unicorn is captured, and Unicorn, for some reason, suddenly slips into a coma the second he is captured. Iron Man brings Unicorn to Avengers Mansion, and Yellowjacket wakes Unicorn, and then cures him of his cellular deterioration. The process drives Unicorn insane, and he accidentally activates a robot, which is driven off by Iron Man, and then is placed in a stasis, waiting for a cure to his mental illness. Months later, Unicorn is freed by a fire erupting at Stark Enterprises. He gets back his suit and attacks Iron Man yet again. Unicorn does not accept from Iron Man the truth, that Titanium Man employed him under false pretenses, and Unicorn later drowns himself in the ocean, attempting to walk to Soviet Russia.
