Giant

Giant is a character of the day who appeared in Tag! We're It...!.

Giant partook in the Hearthome City Tag Battle Competition where he was paired with an unnamed female competitor. Both of them were Dawn's and Conway's first opponents in the tournament. Using a combination of Dawn's attack from her Piplup and Conway's defense of his Slowking, Giant got defeated alongside his tag partner and he got eliminated from the tournament.
