Gigantamax Grimmsnarl seems to have a weird parameter setting. It still hits pretty hard, around 40% more as others. However, its defensive stats (HP * Defense CPM) seems to fall on the range of other Gigantamax Bosses like Butterfree/Snorlax/Lapras.
Without "cheese moves" (low base power moves), this is the first time Zamazenta has to use shield to survive even before enrages.
