Vidar possesses the conventional superhuman physical attributes of an Asgardian male ("god"). His half-giant heritage makes him stronger than the average Asgardian male, enabling him to lift (press) 50 tons.
The product of Odin's dalliance with a giantess, Vidar lived outside the city of Asgard, his existence known to few. He ventured into the city but once to seek redress for the slaying of his way.
Because of the events of Ragnarok, Vidar has suffered the same events that eradicated the rest of the Asgardians.
