# American Cockroach vs Fruit Fly: Who Would Win?

American Cockroach vs Fruit Fly is too close to call. Our 3-round simulation gives American Cockroach a 52% chance and Fruit Fly 48%, which is not enough for either to claim the win.

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: Too close to call
- **Win probability**: American Cockroach 52%, Fruit Fly 48%
- **Decisive weapon**: Evenly Matched Evolutionary Countermeasures

### Round 1: Opening Clash & Speed

American Cockroach seizes the opening initiative with superior agility (35 vs 36), circling Fruit Fly and striking from an advantageous flank.

### Round 2: Clash of Superpowers

An earth-shattering clash as American Cockroach's "Switches from six-legged to four-legged and two-legged running at up to 50 body lengths per second" crashes directly into Fruit Fly's "Has counterparts to an estimated 65% of human disease genes", sending shockwaves through the arena.

### Round 3: Final Resolution

After three grueling rounds, neither creature can establish a decisive edge. Both combatants retreat to neutral ground with full mutual respect.
