I have a much more reliable pattern I personally ascribe to:
Joker: Character I didn't personally want.
Hero: Character I didn't personally want.
Banjo: Character I didn't personally want.
Terry: Character I didn't personally want.
Byleth: Character I didn't personally want.
Min Min: Character I didn't personally want.
Steve: Character I didn't personally want.
Sephiroth: Character I didn't personally want.
Pyra & Mythra: Character I didn't personally want.
Kazuya: Character I didn't personally want.
Ergo I can safely surmise that the next and final Smash Bros DLC characterwill be a character I don't personally want!
You may now applaud my impeccable deductive ability.
