This is Equas, the ancestor of Plusle and Minun:
50% Male / 50% Female
Obey Master - If this pokemon's partner in battle is Nuutro, all of this pokemon's stats increases by 50%. This pokemon also takes all attacks meant for Nuutro.
The only way to get an Equas is to breed a Plusle with a Minun, both must be holding an Equalizer.
The Equas species died out long ago, they were part of an empire full of Equases. This is their powerful ruler, Nuutro:
0% Male / 0% Female
Payback - Whenever an attack is landed on this pokemon (damage inflicting or not), the attacker's HP decreases by 1/4 of its full HP.
The only way to get a Nuutro is to have at least 3 Equases in your party and go to the Nuutro Shrine (he was imprisoned there by Arceus, there will be a story on that in the Fan Fiction forum real soon) at the center of the Equas Ruins. Insert the Summoning Key (event item) into the shrine and a battle starts with a lvl 80 Nuutro.
Tell me what you think, these are my first pokemon drawings with info.
