Diddy Kong (SSBB)/Down smash
Diddy Kong performs a sweep kick hitting in front of him first and then behind him. The front hit has low startup lag and deals 16% uncharged and has decent KO potential overall. The back hit is much slower and weaker making it a lot less useful. Down smash is one of Diddy's most reliable KO moves as while it isn't as strong as his forward smash and it has more ending lag, it has half the amount of startup lag and only consists of one hit making it better in many situations.
