* The only thing BLU can drink is vodka. Anything else will make him violently ill.

* His alcohol tolerance is close to none. He constantly gets blackout drunk and wreaks havoc on RED and BLU mercs equally.

* He lost his eye when he was twenty during a VERY drunken bar fight during which he accidentally gouged his eye in with a billiard stick.

* Despite his constant state of slurred speech, BLU is actually an incredibly personable guy.
