Detonator

The Detonator is an Emblem Heartless that is found in Kingdom Hearts 358/2 Days.

Design
The Detonator is a bomb-like Heartless. Its head is colored red, and is cracked open to show a black face with yellow eyes. Its lower body has two legs, and is completely black. On top of the head, there is a yellow fuse that is curled up, and appears to be burning at the end. The Heartless emblem is located on its head.

Strategy
The Detonator has the highest defense among the other "Bomb" Heartless and counts down more frequently. The explosion it makes is also the biggest, so it is best to attack it from afar. Also note that freezing a Detonator while it is counting down will freeze the countdown. Using fire magic on the Detonator will cause it to explode, using fire magic at a distance is effective, also blizzard magic is effective at any distance because it does tons of damage and you won't have to take the risk of it exploding.
