Napalm Capsule

A Napalm Capsule is one of four capsules from Batman's Utility Belt.

Fighting Catwoman
When Batman was taken off guard and strung from the ledge of a building by Catwoman's bullwhip, he readied this capsule while she ranted. After shaking the chemical began to glow blue and he threw it on her arm, freeing himself.

The napalm wound on her left arm left a scar that Bruce nearly discovered during their date at Wayne Manor, during the Relighting of the Tree Ceremony.
