Mad Ride

The Mad Bumper (マッドバンパー) is an alternatively colored Hot Rod that appears in the Cavern of Remembrance, also being slightly stronger. This Heartless only appears in Kingdom Hearts II Final Mix.

Strategy
Unlike the Hot Rod, the Mad Bumper executes all its moves at a much faster pace, attacking more relentlessly than ever. When half of its HP bar is depleted, a purple aura appears around it &mdash; watch out! It will rev up and rush towards you, and if you're in the way, it will send you flying. It does this rush attack thrice, and pauses for a while before it begins rushing towards you once again.

In all cases, when it attacks you, hit. A well-timed Guard can save you from being sent flying once it rushes towards you. When it pauses, it is open for an attack, so finish it off.

Alternatively, if you're the type to use magic, use Reflega, and make sure that the edges of that spell hit the Mad Bumper - but time it well.
