Thanks to Scourge_lover156 for suggesting this Mega!

Mega emploleon completes my sinnoh starter mega evolutions! Mega empoleon should get the (made up ability) ability Polar Current, which turns water moves into ice type moves after the move gets the STAB boost. It also doubles its speed in hail. It would remain a water and steel type, although this thing looks like it should probably be an ice and water dual type. However, there are too many ice and water types and I love steel so i think it should stay those types. It gets a boost to its speed, defense, attack, and sp attack. Its appearance changes as well- its wings are sharper and the steel comes out of the black covering at the tips. The body is sleeker and it looks more suited for swimming through the water at high speeds. Steel armor aids in its portection.
Stat boosts:
30 speed
20 defense
25 attack
25 sp attack
