Kirby (SSBM)/Neutral aerial
Kirby spins around repeatedly in midair, dealing 10%-6% damage depending on when it hits. This move is officially referred to as Twinkle Star, and was his up aerial in the previous game. The move is rather slow and has an unimpressive hitbox. The move is also very weak with its clean hit being an unreliable KO move even if the opponent is at 200%. It can lead into followups especially the late hit however, it is not super reliable. Overall, the move is not very useful and Kirby is better off using one of his other aerials.
* Due to what is presumably a programming error, the 10% hitbox is listed to start on frame 8 even though the hitboxes do not activate until frame 10. Because of this, the script immediately skips to the 10% hitbox and so the early 12% hit never occurs. It's likely that the early hit was meant to be active from frames 10-17 but due to a timing error (with a frame timer being used instead of a wait timer), it never comes out. This error was carried over from Smash 64 where it was his up aerial, suggesting the code was copied and the error was never caught despite the altered hitbox properties/durations.
