Megastrength is a term used to describe exceptional strength possessed by a humanoid or other lifeform.

When Commander William T. Riker requested that Data bend a bar of parsteel, during a hearing to determine if Data was the property of Starfleet, Captain Jean-Luc Picard made an objection to the demonstration, stating that "there are many life-forms that possessed with megastrength," adding that "these issues are not relevant to this hearing." Unfortunately, for his case, his objections were overruled by JAG Phillipa Louvois. (TNG: "The Measure Of A Man")
