User blog comment:TheHelixYT/No Inkling For Smash 4/@comment-27859332-20150708230044

The only similarity I could see would be their standard attack (?) being a ink shot like how MegaMan shoots instead of a punch or a sword swing. Other than that, the crazy amount of weapons, subweapons and specials in Splatoon would definately warrant a non-clone character.

Also the final smash should be the Ink Strike :)
