Juggernaut vs. Blob
The Blob's powers are immobility. If he doesn't want to be moved, then, by God, he won't be moved. However, that doesnt necessarily mean that the surface that he is standing on will hold out forever. The Juggernaut is, for all intensive purposes, unstoppable. Once he gains speed/momentum he cannot be stopped by any outside force. (Doesn't that go against Newton's Law?) Anyway, if the Blob were to use his powers, and stand his ground against a full speed, charging Juggernaut, who would be moved? Would some kind of ricochet effect happen with Juggs bouncing off Blob? Or would the surface Blob is standing on be ripped out of it's place with him still standing on it?
