The Plasma Coil was a single-shot weapon, which fired a bolt of electricity at enemies at an infinite range, making it ideal for a substitute for the Pulse Rifle if one ran out of ammo. When hit, nearby enemies were shocked by the electricity as well. It could first be bought on planet Joba and cost 150,000 bolts.
Plasma Storm
In Going Commando, the Plasma Coil upgraded to the Plasma Storm, which sent out bolts of radioactive plasma at foes before fading out. After the game was completed, the Mega Plasma Storm could be purchased and upgraded to the Ultra Plasma Storm.
Ratchet & Clank: Up Your Arsenal
In Up Your Arsenal, the Plasma Coil could be upgraded to the Plasma Storm once again after reaching level 5. Once the game was completed, the Plasma Storm could be further upgraded to Omega level.
Trivia
