Lore
Lemmy Koopa is one of the members of the Koopalings, being the smallest one of them all. Like his siblings, his first family isn't too known, but they were rumored to work in a circus, and were killed in an accident during a rehearsal. After this tragic experience, Bowser had taken Lemmy as one of his children and started to take care of the little Koopa.

As Lemmy grew up, his genes from his parents started to show up, as he was standing perfectly on a circus ball at all times, impressing his other siblings. And his magical abilities were also casting bouncy balls. He even stated that he wanted to work in a circus like his parents one day, and wasn't interested much in doing evil deeds. But since his new father was an evil Koopa King, he had no choice but to follow his footsteps at some point.

His first attempt as a soldier of Koopa Clan was when he was situated to take control of Ice Land, with an airship from his father. He wanted to give his natural abilities a try against the enemies to his nation, but unfortunately, he wasn't able to best them. He later attempted to do more creative methods, like using multiple pipes and decoys of himself, throwing bombs of damaging confetti and even attempting to form his own evil circus, sadly none of them worked as well as he thought.

But despite all the hardships he faced as a young Koopa, Lemmy never ceases having fun at his age, and he wants to grow stronger, and think of even more sinister but fun schemes on his own someday. Maybe he'll form a better evil circus, secretly giving audience fun but maybe doing evil from behind the scenes? Who knows?
