The Sasquatch monster encountered SHIELD's Godzilla Squad as they were tracking Godzilla in the Arizona desert. Hurling a huge boulder at the SHIELD helicarrier Behemoth, Yetrigar put SHIELD out of the hunt, and began to himself track their monstrous quarry. Yetrigar ambushed Godzilla at the rim of the Grand Canyon, causing both monsters to topple into the natural wonder. The battle soon escalated when Red Ronin arrived to try and intervene and prevent the monsters from killing each other. However, even Red Ronin could not control two such awesome creatures and was at last forced to fire on the wall of the canyon, causing a rockslide which buried Yetrigar, seemingly killing the giant bigfoot.
