When Commander Riker requests that Data bend a 2.5" diameter bar of “parsteel” during a hearing to determine if Data was the property of Starfleet, Data easily bends the bar in half and places in on the table. Captain Picard objects to the demonstration, stating that there are many lifeforms that possess “mega-strength” so the demonstration is irrelevant. (TNG: 2x09 "The Measure Of A Man")
Many races seem to be physically stronger than Human; Vulcan, Klingon and Romulan immediately come to mind, but they would obviously not qualify as possessing “mega-strength”. Has there been any depiction or mention of any particular race or individual demonstrating strength on par with or superior to Data's?
