He is known to have a strong oderous stench on him, as he showers once a month.
He is first seen when he pickpockets some people as he was being bullied by Duncan Matthews. Saving him, Scott Summers fends off Matthews long enough for Tolansky to escape. He then meets Principal Raven Darkholme, as Mystique, and recruits him to be the first young member of the Brotherhood of Mutants. She has him to pretend to join the X-men long enough to inform her about the Danger Room and everything else. He first meets Nightcrawler and has it out with him for saying he smelled like "unwashed liedherowsen." Finding themselves in the Danger Room by accident, they are blasted by machines and leaves, not remembering any detail thanks to Professor X.
He then meets other members of the Brotherhood, Avalanche (Lance Alvers), Blob (Fred Dukes), Quicksilver (Pietro Maximoff), and Rogue, who later leaves and join the X-Men.
WHile Mystique was gone, Boom Boom (Tabitha Smith) decided to live with them until Mystique had kicked her out and Wanda Maximoff, the Scarlet Witch, moved in.
Toad was in love with Wanda, and she wasn't. He risked his life rescuing Wanda from her treacherous father, Magneto, and had earned her friendship, which was a start.
Years in the future, the Brotherhood will be known as the Freedom Force working for S.H.I.E.L.D..
