Grimlock's New Brain

Anti-electrons are released and wreak havoc on whatever Transformers they encounter, as well as a power generator deep beneath Cybertron's surface. Grimlock takes a nasty hit himself before the Autobots tamp this problem down. Surprisingly, though, Grimlock is now the smartest Transformer of all. As part of his new genius attitude, he deduces that the Decepticons caused the trouble in the first place and what their next move is. Meanwhile, those were the last of Galvatron's anti-electrons. The dormant Unicron holds more, however setting the stage for a showdown.
