The Weightlifter has sworn to become the strongest man in the entire world. He runs around the city looking for things to pick up…and he wants to pick up EVERYTHING. As long as an object isn’t nailed to the ground, he’ll scoop it up and try to lift it over his head.
The only thing that the Weightlifter pays attention to is how heavy something is. If it weighs more than the last thing he lifted, then it’s just what he needs, whether it’s a person, an auto, an elephant or a house. No challenge is too big for the Weight Lifter!
