ThatGuyZ posted... Galvantula. Can learn both Toxic and Thunder Wave if you want to hinder your opponent, plus it's Speed and Sp. Attack is pretty good. It also has an advantage over Steel types, being part Electric.
Scolipede is faster though, and its Attack is better than Galvantula's Special Attack (by three, so negligible, especially in game). And Scolipede gets Toxic AND Toxic Spikes. It cannot paralyze, however.
Bug/Electric is probably a better offensive typing anyway though.
