Lemmy Koopa is one of the seven Koopalings, who are Bowser's minions. He made his debut to the Mario Kart series in Mario Kart 8 and was playable for the first time in any game. He also has a tire service, named "Lemmys tire service".
Lemmy Koopa is assumed to be the second oldest of the Koopalings. In New Super Mario Bros. Wii, Lemmy Koopa's preferred weapons were bouncing balls that would knock Mario off the edge. Is there really any weapon that is better than bouncy balls? Nope, and that's why he chose them.
Lemmy Koopa is a golden-yellow color like all other Koopas. He has black spike bracelets, and his shell is orange and also covered in spikes. His head happens to be green with two orange markings on either side. Lemmy Koopa's hair is very long, and it is divided in six section, each of them being yellow, pink, or blue. He also has a yellow ponytail on the back of his head. On his hands and feet, he has sharp white claws, he has four fingers on each hand and three toes on each foot. He also has white pads on the plant of his feet.
Lemmy is most probably named after Lemmy, the lead singer for the metal band Motorhead.
Although he is the assumed second oldest of the Koopalings he is the smallest of all, in fact he has small arms, small hands, small body, small legs and small feet.
