I am a few years late on this comment, but no, this wiki is not exactly an "alien species" wiki. It has some aliens, but the rest of the creatures on here are Dinosaurs, Kaijus & Kaijins, some Pokemon, Monster Hunter wyverns and other MH monsters, some ARK dinos, creatures, and bosses, and there's a few robots on this wiki aswell..

@MechaGorosaurus So it's a copy of "All Species wiki" then? Oh wait, that wiki also has species from real life. Also, "MH monsters" you say?
