Vanishing Gungaroo

Vanishing Gungaroo is one of the Mavericks of Mega Man X7. He actually starts out in a Ride Armor similar to a mother kangaroo, and you have to fight him in a Ride Armor battle. Once his Ride Armor is out, you can pummel him a little bit more before he destroys yours. And once you're both on even ground, use Wind Cutter or Souenbu to finish him.
