Rimworld Alpha Animals Tier List May 2026

Too dangerous, low value, or broken mechanics.

Why A-Tier (for the chaos): A Mime looks like a normal human wanderer. It joins your colony, does work, eats food, and laughs with your pawns. Then, suddenly, it transforms into a feral, predatory monster and eats your cat. If you can spot the signs (they never social fight, eat raw food obsessively), you can banish them to a locked room and turn them into a janitorial executioner for incoming raids.

Why C-Tier: It burrows into your colonists’ stomachs and slowly drains their nutrition, but occasionally regurgitates Hemogen packs. With the Biotech DLC, this is mildly useful for Sanguophages. Without Biotech? It's a medical bill waiting to happen. De-worming surgeries are annoying.
