He could also alter his personal mono-directional gravity field beneath himself to make himself virtually immovable as long as he was in contact with the ground, although an incredible force can uproot him, along with a chunk of whatever he is standing on. The only beings on record to have been able to move the Blob against his wishes are the Hulk, Juggernaut, and Strong Guy (powered-up near his limit by absorbing kinetic energy), although Colossus has managed to lift Dukes by digging underground and raising the piece of earth Dukes stands on, stating this as an exception to his immovability. Magneto once was able to move the Blob by lifting the ground under the Blob's feet via metal pipes. Despite his appearance, the Blob's speed and agility are those of a fairly athletic male of normal stature, a fact which frequently catches his opponents by surprise.
