Maple Quiz Groups?

EDIT: Thanks Meta. Needed that. Where is that NPC?

He isn't in the game anymore since he was a Christmas Event NPC.

both are Elliza

I've only gotten the area boss, which is Elija.

Who's that Pokemon? No really, I've looked up everywhere in the game that NEXON's released thus far in GMS for this NPC; I avoided NPC lists of places made by Wizet considering this NPC has the Nexon art style.
And yeah, I noticed a lot of recurring NPCs.
