Equipment[]

Homemade Bomb
Joanie Boom Equipment
Joanie Boom has always been fascinated with explosions, and after joining the Rediesel Wrenches, this passion became even more intense. Every time she fights, she uses all kinds of her own carefully-crafted bombs to blast away the Eclipsites with fierce explosions and fearsome flames. In her opinion, there is nothing more wonderful in the world than a good bomb.
