Jimothy
Jimothy is a melee speedster unit, essentially an upgraded version of Framerate that punches enemies at an even faster rate. He was released as a 50,000 gem limited edition unit, making him one of the most expensive units to obtain in the game. Like Framerate, he overclocks himself during his ability, unleashing an even faster flurry of punches at the target.
Kit
Attack: A relentless barrage of punches, faster than Framerate's. Special: Overclocks himself into an even quicker flurry of punches.
Review
Jimothy is essentially a slightly better Framerate, faster attack speed and a bit more damage, but not different in any meaningful way. Because he was a 50,000 gem limited edition unit, a lot of players feel he is simply not worth the price given how close he is to a unit that is much easier to obtain.
