According to Croup:
This one is from the Ultimate Spider-Man cartoon. In episode 14, Spider-Man and friends try to stop the "Awesome Android", a creature which can grow exponentially from consuming inorganic matter. They must also contend with Juggernaut, who was seen rampaging in the city earlier in the episode.
Having difficulty dealing with both at once, the team instead pits them against each other by tricking Juggernaut into attacking the android. But even the Unstoppable Juggernaut's attack does little good, and the android lifts him like a bug before swallowing him up! The heroes look on, horrified, as Juggernaut becomes merely a bulge in the gray monster's body, traveling down his length until he . . . is expelled out from the foot, completely naked.
Lacking his helmet, Juggs is then punched out by Spider-Man with a mighty blow. :D And later on he is lead away in cuffs. Apparently the police had some shorts on hand for him to borrow . . .
