The Lightfoot Clone is very muscular, having been described by Tails as "eating his greens, because he's grown up really big and strong." He also carries "a heavy heavy-duty thing."
The Lightfoot Clone Type B was one of many Johnny Lightfoot clones, being specifically created with emphasis on brawn and low intelligence. He ended up meeting a confused Sonic and Tails, who thought he was the real thing. Sonic and Tails told him they were "type S" and "type T", respectively, and he begrudgingly pointed them to a cavern.
As a Type B clone, the Lightfoot Clone is "big, brawny, and brainless." However, he is rather affable, given that he pointed Sonic to a cave he needed to enter.
