Cosmo is the best at the moderator job but it's also the worst because it's the most obnoxious about it. It rules this server with an iron fist but the rules it makes up are mostly arbitrary and also deviation is punishable by death ( ban ). Cosmo rules its 5 people friend server and demands everyone text 'good morning' everyday within a 5 minute window, and will ping those who don't every hour until they reply to make sure they're okay, so god forbid you oversleep. No cursing. No pinging it ( only it can ping others ).

I also think Eddie would make a good mod - He has the time. And he's also way more reasonable than Cosmo would ever be. And what is Mr. Flynn if not the Discord Mod of this timeline, anyway...? He'd do a good job if you can stand the horse emoji reactions to every message.

Also, in the old RP group the twins come from, specifically this Xander was the moderator of the interdimensional Discord Server and did a decent job. So yeah, actually, Xander is the best one.
