|Real Name||Herbert Landon|
|Powers and Abilities||None Known. Formerly: Able to Grow in Size, Energy Blasts, and Electricity Absorption|
Herbert Landon was a scientist who despised mutants. Using the research notes of a formula that was developed by his former colleague Henry McCoy, Landon and his Herbert Foundation, using money provided by the Kingpin, began producing a chemical designed to kill all mutants.
The Hobgoblin discovered what he was doing, he began threatening Landon, forcing Landon to bribe him to keep his mouth shut. After a brawl ensued between Spider-Man, Hobgoblin and Wolverine, Landon was doused in the chemical and was turned into a thirty foot monster capable of absorbing massive amounts of energy and firing deadly blasts. However, he needed such a massive amount of energy that he was in constant agony from hunger, causing him to attack wildly and consume all sources of energy in his path. Spider-Man and the X-Men would stop him, and mostly restore his human form.
After being released from the hospital, Landon, now in a half human, half mutant form, began to work as the Kingpin's assistant, replacing Alistair Smythe. Despite his appearance, he showed no sign of his monster form's energy powers. Landon would help Fisk carry out his evil deeds, focusing on biological instead of mechanical science to further Fisk's goals. He would eventually turned Smythe into the Ultimate Slayer, though Smythe would eventually defeat his brainwashing with the help of Spider-Man, who had discovered that Fisk was still keeping Smythe's father, Spencer Smythe.
Herbert Landon was voiced by David Warner.
Landon's post-mutation appearance strongly resembles the Batman villain known as Two-Face.
