~ BTD6 description
Plasma Vision is the 2nd upgrade of Path 1 for the Super Monkey in BTD5. It makes the Super Monkey shoot plasma balls instead of lasers that can pop any type of bloon, as well as increasing the number of bloons it can pop. It costs $4250 on Easy, $5000 on Medium, $5400 on Hard, and $6000 on Impoppable.
Plasma Blasts returns as the 2nd upgrade of Path 1 for the Super Monkey in BTD6. It also makes the Super Monkey shoot plasma balls instead of lasers, but neither of them can pop Purple Bloons without special upgrades. Plasma Blasts shoot at double attack speed and have 3 pierce (+1 more pierce than Laser Blasts). Just like in previous versions, Plasma Blasts allows the Super Monkey to pop Lead. It costs $3825 on Easy, $4500 on Medium, $4860 on Hard, and $5400 on Impoppable.
Always buy this upgrade whenever possible, because the +100% attack speed bonus for an already fast-attacking Super Monkey is incredibly useful for pretty much any upgrade, including further upgrades after Plasma Vision, such as Sun Avatar.
