Hmmm...it's a okay choice,but why Athena?
HWYR if Smash 6 have Duke Nukem as a playable character?
Duke is another obscure but likable character, just like Ryu (Ninja Gaiden), and Kunio (Kunio Kun), so I would like it.
HWYR if in Smash 6, Waluigi, Bomberman, Rayman, and Lilac (Freedom Planet) get promoted to playable, but in return, Goku (Dragon Ball), Medabee (Medabots) and Jibanyan (Yo-Kai Watch) gets an assist trophies, and mii costumes. While Dragonoid (Bakugan) and Suezo (Monster Rancher) just get spirits. And Waluigi's piranha plant gets demoted to one of his special moves. There are plenty of obscure Non-Nintendo series represented in Smash already, such as Kunio Kun, Bayonetta, No More Heroes, Fatal Frame, Mana, and Babylonian Castle Saga.
