I'd expect Crunch to be slashed with Earthquake as a coverage move? Since PUP is key for boosting and SP is key for priority, but Crunch and EQ are both coverage so they serve similar purposes.Fake Out is crazy weak and begs you to switch something to force MegaKan out. Sucker Punch is pretty much always going to be better.
Also, standard is Return / Earthquake / Sucker Punch / Power-Up-Punch, with Crunch getting slashes on either SP or PUP for consistency. It packs much more power that way.
But yeah, Kangaskhan is so busy with those five moves that it doesn't have room for anything else.
Knock Off is definitely superior, but it's only an option for Pokebank.Well its takes out 30% on almost anything.. And I think knock off is better than crunch it got more bp on first hit and why not low kick? It's ou it got mosly 120 bp
Low Kick, like Fake Out, is worthless against Ghost-types, Kangaskhan's biggest nemeses due to being immune to both its most powerful attack and its boosting move.
