The only characters that do not have custom moves are Downloadable Characters, although only Mewtwo was planned to have them; it is unknown why they were cut., though it was most likely due to time constraints, as creating new Custom Moves would delay the release of the character.
Obtaining all Custom Moves is one of the 140 Challenges in Super Smash Bros for Wii U. Obtaining all Custom Moves is also one of the 105 challenges the Nintendo 3DS version as well. Both challenges can be completed by using a Golden Hammer.
