Doctor Arachnoid - Mutated Genius

Doctor Arachnoid was a villain that appeared in the cartoon series "Mighty Max".
Formerly known as Dr. Stephen Huxley, this scientist was researching the medical benefits of spider toxins when something went wrong. A co-worker was secretly modifying the formulas Huxley created in order to use them for biological warfare. When Huxley tried the serum on himself, it mutated him into a human-spider hybrid. Now sporting six eyes and arms, the slightly insane Huxley dubbed himself Arachnoid and tried to use giant mutant spiders to remake the world in his image.
