I wonder what Grimmsnarl looks like without all that hair. For example, those claws look like claws until you see his animation, turning those claws into a whip full of hair.
Gigantamax Grimmsnarl really reminds me of Aku. Please tell me I'm not the only one
If anything, it reminds me more of Beelzemon from Digimon, especially since Impidimp & Morgrem remind me of ImpmonPersonally, he reminds me more of Chernabog.
Although I wonder what's the deal with the Regi Duo being potentially electric and dragon.
