Reactive Comet (abbreviated as R-Comet) is a sub-weapon for Jason in Blaster Master Zero 2. It is found on Planetoid B-2.

Overview

Activating Reactive Comet consumes 1 ammo (out of a maximum of 8) to spawn a shield bit which orbits around Jason for 8 seconds and passes through rubble and walls; up to 4 bits can be on-screen at a time. Each bit can absorb one shot or attack, preventing it from dealing any damage. Bits will also defend Jason against contact damage, dealing 2x G-Blaster damage and opening up certain enemies to Blast Counters.

Reactive Comet bits also perform special functions when Jason performs a Blast Counter, though their damage is reduced to 1x G-Blaster damage in the process:

Deploys a bit that protects from attacks and launches with an ice attack when activating a BLAST COUNTER.

The ice elemental version, Absolute Comet (abbreviated as A-Comet), is found on Planet Divido. Like other elemental sub-weapons, it only comes with half the ammo capacity of its neutral variant. It functions the same as Reactive Comet, but now has a chance to freeze enemies with every attack, though some enemies are immune. While active, Absolute Comet bits imbue all Seeker shots with the ice element and convert G-Blaster shots to ice-element bullets if they happen to pass through the bits; additionally, having this elemental sub-weapon equipped transforms EX-Charge's charged shot into a 5-shot ice spread.
