A Plasma Blast is a green and explosive energy ball used by Cortex in Crash Bandicoot and Crash Twinsanity. Cortex first uses it in his boss fight in Crash Bandicoot, where it must be spun back at him in order to make him lose a hitpoint. The same strategy is reused in Crash Twinsanity in his boss level, but due to Cortex being a playable character, it can be used by holding the shoot button and then releasing it, causing a big explosion.
- In Crash Twinsanity, if the player double-jumps on the plasma blast shot by Cortex, it will glitch and still be following Crash when he's on top of it, therefore reaching massive heights which he shouldn't usually reach. After a while, the player will fall off and die.
