Silus's Abomasnow

Silus's Abomasnow (マシューのユキノオー, Mashū no Yukinooh) is the thirteenth Pokémon caught by Silus in the Hora region.

History
Abomasnow originally debuted in Skip to My Snover!, as a wild, part of a pack of Snover and Abomasnow, which was stealing food due to all the berries on Route 9 dying out. It then stole Silus' backpack, causing the group to give chase. However, upon retrieving the backpack, they noticed that Snover was greatly upset, as it was still very hungry, and so Silus offered it an. This act of kindness caused Snover to evolve into Abomasnow. The group parted, but Abomasnow decided to follow them, saving them from the Team Rocket trio, before deciding to join up with Silus.

Personality
As Snover, it lived up to its species reputation of being curious, walking right up to Silus' group and stealing their food. Perhaps its defining trait, is that it is a very emotional Pokémon, being moved to tears after Silus reclaimed his backpack, and then, in a reversal of moods, showing great gratitude, when Silus offered it a berry; going so far as to evolve.

As Abomasnow, this affectionate personality isn't diminished, as it hugs Silus to show its appreciation. Abomasnow dislikes its Pokéball, only going inside when it is exhausted, injured, or when there are size constraints. Otherwise it prefers to walk, carrying Silus on its right shoulder. Clair claims this is because Abomasnow considers Silus a member of its pack. This behavior, mysteriously, subsides by Brave for Braviary!, as it is seen in its Pokéball from then on.

As Snover
As it was only briefly seen as Snover, its abilities aren't well known. Snover was shown to be incredibly agile, able to dodge Silus's Charmander's Flamethrower attack with ease, and then return fire, driving Charmander back despite its double type disadvantage. It also had the Ability, allowing it to conjure up snowstorms at will.

As Abomasnow
As Abomasnow, its abilities increase. It retains the Ability, Snow Warning, and also gains several new, more powerful, attacks.
