Off topic but I'm REALLY surprised we haven't gotten extra costumes/skins for some characters, whether it be paid or free. I'd personally like to see within reason
Mega Man - Proto Man, Bass
Link - Zora Armor, Magic Armor, OoT, Twilight Princess
Donkey Kong - Punch Out Wii
Young Link - Razor Sword/Gilded Sword + Mirror Shield
Ganondorf - Twilight Princess, Hyrule Warriors
Snake - Big Boss
Luigi - Mr. L
Bowser - Dry Bowser
Yoshi - Boshi
Cloud - KH Cloud
Zelda - Twilight Princess, Hyrule Warriors, BOTW
