Edmund McMillen and Tyler Glaiel's Mewgenics is a pure nostalgia bomb, rightfully following the legacy of these popular indie creators. A large part of this roguelike is encountering a variety of enemies, and since the game consists of several acts, players will naturally want to know all the small and large enemies they will encounter. For that reason, this guide explains all the bosses in the Mewgenicsincluding secrets, intruders and event exclusive mobs.

Mewgenics Boss Guide
Mewgenics follows a unique structure when it comes to categorizing managers. In particular, you will find five main types of these monsters in this game:
- General Threats: Each act has a number of creatures, such as Kittens, Flies, Cat Caller, etc., that you have to fight in different stages to progress.
- Mini Bosses: These are slightly more difficult encounters, normally around four in the first zone, with fewer appearing as you advance to new arenas.
- Final Bosses: Each chapter i Mewgenics has a couple of final bosses (usually one), so you can meet about seven to eight of them in an entire act.
- House bosses: These invade your home on their own after you clear certain areas.
- Special Managers: Certain events along the way allow you to fight these rare mobs.
