Mega Manectric is a pure Electric type, and has a slightly better design compared to regular Manectric, with like some of the others, just a bit more too it compared to the original. Overall though, I still just find the design of Mega Manectric eh, nothing real exciting. However, Mega Manectric can be decent in battles, with it having Intimidate for its ability, so can take some hits from the physical side, and can deal good damage back on the special side. Mega Manectric is something I like, but end of the day, it is still just a pretty meh Mega, so that's why I ended up ranking it here.
