The first superhero of all time, Captain Caveman, has made his big screen debut in Avengers: Infinity War.
But Marvel shocked everybody by introducing the prehistoric man beast Captain Caveman.
Thanos, having already placed five of the Infinity Stones on his gauntlet and dispatching a number of out-of-contract Avengers on the way is, towards the end of the film, desperately searching for the Soul Stone in Alaska.
But he unintentionally wakes Captain Caveman from his frozen slumber.
Upon waking, the hairy superhero promptly eats the Soul Stone before dispatching Thanos into the Bering Sea with his club and triumphantly shouting “Unga bunga!”
Caveman then goes on to team with the Teen Angels in the fight against Thanos, prompting hilarious debates with Black Widow and Scarlet Witch about dressing appropriately for galactic war and feminism.
Captain Caveman will created via CGI, with Andy Serkis providing the motion capture.
