EDIT: Well, I was ninja'd YET AGAIN. *rage face* But, this works all the same for ShinyUmbreon, so this doubles for Xulek and ShinyUmbreon.
Well...your avatar tends to change.
You know what else changes a lot?
Ditto.
Because it knows transform.
Mew can also learn transform.
What do they have in common?
There shiny form is blue.
Who else has a blue shiny form?
Voltorb, Pawniard, and Mienfoo.
So how to decide out of those three?
Well, both Pawniard and Voltorb have an "R" right before the final letter of their name. That singles Mienfoo out.
Plus, you seem pretty kick-butt.
Hence, you are Mienfoo.
