Custom Robo
The main objective of the game is to finish the storyline by collecting every Custom Robo and battle part, while winning every battle that moves players along through the story arc. In Custom Robo battles, the object is to reduce the opponent's hit points from 1000 to 0 by using different Robos, guns, bombs, pods, and dash attacks. Custom Robos are arranged in groups that are similar to their abilities. The endurance bar is located above the player's hitbox; once it runs out, the Custom Robo gets "downed" which means that it stays fallen for a couple seconds. After the Robo gets up, it goes into "rebirth" mode, a temporary state of invincibility lasting 3 seconds. Should the player repeatedly lose the same battle, the game will offer the option of reducing the opponent's initial health, in order to make the battle easier. If players continue to lose several times, the degree of handicap offered increases up to 75%, giving the opponent a starting HP of 250, rather than 1000.
