Redmond and Blutarch Mann are the two sons of Zepheniah Mann, whom own the two halves of Mann Co., respecively being RED (Reliable Excavation Demolition) and BLU (Builders League United). They clashed for about a century, hiring mercenary teams and creating life-extending machines to try and kill the other to claim his industry. Now that they're dead, they want to send each other to hell, and have hired mercenaries to do so. They both insult each other frequently and call others "poor people".
