Mr Merrilocks is a creepy guy who climbs walls and looks in peoples windows. He has a knife but he never uses it as he doesn't want to get it dirty. Nevertheless, he is still a wanted criminal across League space. He apparently lives mostly on Earth but he could just as easily jump ship and travel the Galaxy.
Mr Merrilocks can also leap really high, to reach the windows of high skyscrapers. He apparently lives in some kind of burrow in a forest.
