Fakemon: Ralts, Kirlia, Gardevoir.

Where's the Mosanto Form Gallade? Well, since the Mosanto region is Canon with the B2 Nuzlocke universe, the reason Mosanto Gallade doesn't exist is because Mosanto wasn't connected to the mainland when the parasitic virus spread among the other region's Ralts Populations, unwittingly spread as people travelled among the regions, introducing it when they came in contact with the other region's Ralts Breeds. The virus, attaching itself to, what was effectively, junk cells in males, violently and painfully change a male Kirlia when they come in contact with a Dawn Stone, altering their form into a Gallade, preventing them from actually evolving. Mosanto Form Ralts, however, LACK the specific junk cells which the virus requires, meaning when the virus initially tried to take hold on the Mosanto Ralt's population, also unwittingly spread when it was re-established with the mainland, the virus could not take hold, thus, NO Mosanto Form Gallades can be created... Science! 83

Ralts - The Feeling Pokémon.
RALTS are small and incredibly frail Pokémon, preferring to keep a distance from anything that they consider threat. Simillar to it's mainland variant, the Mosanto variant of RALTS spouts a large, hard helmet, often mistaken as hair, however, Mosanto RALTS possess a larger, harder version of this helmet, which, while offering extra protection from behind, is too heavy for it's body to properly use and hinders it's movement. RALTS are friendly by nature and have Empathic abilities, trainers who catch a RALTS often find their RALTS will show the same emotions they themselves are currently showing, this is because, to try and become closer with their trainer, a RALTS will try and link up to their trainer's brainwaves to better understand them. In the wild, RALTS can be found in groups, loyally following their parental GARDEVOIR everywhere they go.

Kirlia - The Emotion Pokémon.
When a RALTS evolves into a KIRLIA, they quickly learn they have a great talent for FIRE type moves, blasting them from their fingertips like a firework. Unlike it's non-Mosanto counterpart, a KIRLIA's dress is long, thick and heavy, unsuitable for the elegant dances of it's mainland counterpart, however, what it lacks in dance moves, it more than makes up for in bulkiness, being relatively hardier than the non-Mosanto variant. Eager to learn, a KIRLIA will trail slightly behind it's Trainer, acting as their secretary of sorts, preferring to do their trainer's lesser work so that their trainer can focus on more important matters, wether they exist or not, it's better to go along with this, as it makes the KIRLIA happy to know that they're helping out and learning something at the same time.

Gardevoir - The Spellcaster Pokémon.
Mosanto region GARDEVOIR lead a mostly solitary lifestyle, preferring to practice their arts, weather Psychic or Magical, in peace, only interacting with others to teach younger RALTS and KIRLIA, to share their secrets with other GARDEVOIR or to form breeding pacts when it comes time to produce young. When it's raised by a caring trainer, a GARDEVOIR will be forever loyal, risking life and limb if it feels like it's trainer is in danger, much like it's mainland counterpart, a Mosanto GARDEVOIR possesses the power to tear open black holes in the fabric of reality. GARDEVOIR tend to ignore others in distress unless it can directly affect them or their species, it's a popular legend in Mosanto that the GARDEVOIR refrain from interfering because they prefer to watch events unfold and learn from the actions of others.
