It makes no sense for him to be first. If you make him first then I say, idk,
Kihara Ransuu,
Yuna Williams,
Marii Yukari,
Sora and
Artemis Fowl beat him and should be above him.
Like, this isn't an equal rock, paper, scissors relationship.
Gooday beats some of the people on this list. Gooday is beaten by probably thousands of fictional characters from which we list dozens at minimum. The people on the list beat all of those characters.
In other words, he can't be considered "strongest" given that he can be defeated by regular humans. He just has a favourable matchup. I'm fairly sure the way the list handled that in the past was always to not consider the weak character with a favourable matchup. (Similar to how characters that only produce draws get tossed out)
