hi I'm vkmax and i will tell you what Pokemon evolves into electross.
tynamo evolves into electric.
you can find tynamo in chargestone cave on the top floor.
tynamo evolves at level 39 into electric.
to evolve electric into electross you need to get the thunder stone.
you can get this from chargestone cave or on the top floor of the shopping mall outside opelucid city.
if you want to get electross i reccomend waiting till electric gets to level 44 before evolving it.
you could also teach electric or electross thunder wild charge or u-turn.
