Gravurwa

Gravurwa (グラビアゥワ) is a Reaverbot from The Misadventures of Tron Bonne. It is the boss of the third stage from Shala-Kun Ruins. This reaverbot's strategy is different from the previous one. At first, it sits still deploying tiny grenades. You have a chance to hit one of the open holes with the drill. If you do or if you don't, Gravurwa will deploy its spinner from the bottom and he'll start chasing after you slowly. After a few seconds of chasing you, he'll wind up and once he finds you, he'll charge at you at full speed making the entire room tremor. Its relatively easy to dodge as long as your not in his path. Afterwards, he settles back down in his resting position and the process keeps repeats until you defeat Gravurwa.
