# Planarian vs Polar Bear: Who Would Win?

Polar Bear wins this matchup, with a 85% chance of victory against 15% for Planarian in our 3-round simulation. Its biggest advantage is strike power, 99 to 13 out of 100.

The simulation puts both animals on neutral ground. In the wild, terrain, the size of the individual animals and plain luck would all change the result.

## Verdict: Polar Bear

### Round 2: Clash of Superpowers

Polar Bear detonates its biological specialty: Jet-black skin under hollow, clear guard hairs, with up to 10 centimeters (4 inches) of fat beneath it. The sheer destructive payload overcomes Planarian's 42 armor rating.
