History
Alchemax of Earth-50101 build their supercollider in the handing portion of a skyscraper in the middle of Mumbattan. One day Spot from another universe showed up there and commandeered their collider, using his powers to teleport all personnel out and locking himself behind a forcefield. He activates the supercollider and jumped into it in order to increase his own power, after which he departed back to his home reality. Back in Mumbattan however, the collider exploded and the building crashed down onto the streets below, with only the involvement of multiple Spider-People preventing massive civilian casualties.[1]
