# Green Sea Turtle vs Marine Iguana: Who Would Win?

Green Sea Turtle wins this matchup, with a 62% chance of victory against 38% for Marine Iguana in our 3-round simulation. Its biggest advantage is armor and toughness, 21 to 14 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: Green Sea Turtle
- **Win probability**: Green Sea Turtle 62%, Marine Iguana 38%
- **Decisive weapon**: Navigates with a map that is at least partly based on Earth's magnetic field

### Round 1: Opening Clash & Speed

Green Sea Turtle seizes the opening initiative with superior agility (46 vs 45), circling Marine Iguana and striking from an advantageous flank.

### Round 2: Clash of Superpowers

Green Sea Turtle unleashes its core evolutionary weapon: Navigates with a map that is at least partly based on Earth's magnetic field. Marine Iguana's defense rating of 14 is severely tested as the attack breaches defenses.

### Round 3: Final Resolution

Deep into round three, Green Sea Turtle's superior endurance and firepower seal the contest. Delivering a definitive blow backed by Harmonia's soundtrack, it incapacitates Marine Iguana.
