Gravurwa (グラビアゥワ Gravurwa?) is a Reaverbot from The Misadventures of Tron Bonne. It is the boss of the third stage from Shala-Kun Ruins. Gravurwa sits still deploying tiny grenades around itself. The player has a chance to use the Servbot Borer and damage one of his holes. Regardless of what is done, the Reaverbot will get up and start chasing the Servbots and Finkel slowly for a while. He soon winds up to charge at the player. As long as the Finkel get out of the way, the player will be safe. The process repeats until all open holes are destroyed.
