Wait a minute...if Hugh is becoming a main character...and be given a Pokedex... and isn't named after a game...is there hope for Wally now in the RSE remakes to become a main character?
No. Different situation.
Wally can't be named, Hugh can.
Since there is no games left to give a name for him, they had no choice but to call him Hugh. And besides, they could always change it.
