Toad first appeared as part of Magneto's Brotherhood of Evil Mutants. Toad, like the rest of the brotherhood, was treated cruelly by Magneto, but was especially disliked by the master of magnetism for his sniveling personality and general uselessness.
When the Brotherhood disbanded Toad, finally sick of Magneto's bullying, abandoned him, and spent some time stalking former teammate, the Scarlet Witch.
Toad eventually formed his own brotherhood, which served as a revenge squad against other mutant groups. After this brotherhood was defeated by Cable's X-force, Toad largely disappeared from Marvel comics. Recently the Toad has returned with an enhanced power set and a fighter's mindset.
Powers and Abilities
Toad's mutation has always been unstable, resulting in ability fluctuations over the years. Originally his only power was a superhuman leaping ability. As time has gone on he has gained and lost a variety of frog based ability's such as: A long prehensile tongue, the ability to spit gray goop, underwater breathing and communication with amphibians. One consistent trait is Toad's mutation causes him to release an offensive smell.
Appearances in other media
X-MenToad appeared as the quaternary antagonist in the 2000 movie X-Men, played by Ray Park. He was a member of Magneto's Brotherhood and possesses enhanced leaping capability and acrobatic speed, agility, dexterity, reflexes, coordination, balance, a sticky prehensile 13-foot (4.0 m) tongue, and the ability to spit an acidic mucus that hardens almost instantly. He has a different personality from the comic incarnation, confident and comical. Toad also appears to have some scientific ingenuity, as he was seen working on Magneto's machine that can induce mutations in normal humans.
Toad battles Storm, Cyclops, and Jean Grey all at once in the battle in the Statue of Liberty, he starts by locking Cyclops in a display case, sends Storm to the second floor and spits slime on Jean Grey as she stops him in mid-air. Storm revives to stop Toad from harming Jean but is quickly subdued and is knocked down an elevator shaft. Storm flies up again and blows Toad out of the statue, his tongue latching onto a support beam to stay alive. However, Storm strikes his tongue with a lightning bolt, causing him to fall into the Hudson River. It's unclearly if he survived the fall or not.
X-Men: Days of Future PastToad appears in X-Men: Days of Future Past as a minor villain in the past timeline of the movie, in a military bunker with Havok and Ink prepared to be sent to Trask Industries to be experimented and tested on. However, Mystique, disguised as the colonel, attacks and kills the soldiers and makes a getaway on a Military plane with Ink, Havoc, and Toad himself. He is later seen towards the end of the movie working as a fry cook watching Magnetos speech on persuading other mutants to join his cause, something that Toad nods his head to.
