Toad (Mortimer Toynbee) is a Marvel Comics supervillain, an enemy of the X-Men. Created by writer Stan Lee and artist/co-writer Jack Kirby, he first appeared in X-Men #4 (March 1964).
Toad was originally a weak, hunchbacked mutant, with a superhuman leaping ability. He was Magneto's sniveling servant in the 1960s line-up of the Brotherhood of Evil Mutants. He eventually led his own version of the Brotherhood, which was more involved in petty crime than mutant liberation.
Mortimer Toynbee was born in York, England, and was quickly abandoned by his parents and spent many years in an orphanage, where he was constantly tormented by other children due to his ugliness and strangely shaped body (as his mutant appearance was present from birth). He was considered to be mentally inferior due to his extreme shyness and mild learning disabilities during his primary school years, though he was actually quite intelligent. He dropped out at an extremely early age and decided to fend for himself. Based on years of abuse and knowing full well he was a freak, Mortimer developed a severe inferiority complex, becoming servile to anyone that showed him the slightest bit of affection.
Later, he was recruited into Magneto's original Brotherhood of Evil Mutants, becoming Magneto's sycophantic 'toady'. Toad believed that Magneto loved him, while the mutant mastermind considered this henchman little more than a human shield. He also developed a crush on his teammate Scarlet Witch, but she did not return his feelings as she was repulsed by his appearance, mannerisms, and lack of hygiene.
