Pechgeus is a large red armoured lion-like robot, and is first found in the 4* multiplayer mission "Red Lightning Claw". Defeating him can get you the Pech Parts.
Pechgeus will mainly attack by slashing at you with its claws when you are in close range, and will also kick you with its back legs. It also jumps into the air doing a flip and attacks you from above. While you are at long range, he will throw his shuriken's at you. Attacking his legs will stun him for a short time. Pechgeus is weak to Blunt attacks, so using Break Patches is helpful
