Grinder 2.0 is the 8th Guardian in Blasterball 3. You can find it on Stage 80. Its appearance and attacks are identical to that of the original Grinder, but it also has an additional attack. Grinder 2.0 can periodically fire lasers that make the paddle move more slowly for a few seconds. Sometimes Grinder 2.0 will only fire a single shot, and other times it'll fire a spreadshot consisting of three (or sometimes five) lasers.
