Almandina

Almandina is dubbed the literal "Crown Jewel" of the Buio Totale experiments and acts somewhat spoiled and princess like. She bosses a lot of the others around, but in all honesty is trying to help them out. 

 Personality wise, she's usually pretty happy and positive, as she didn't have to go through what some of the other fusions had to go through, and kind of doesn't fit in with some of the more rough fusions like Basil and Eyon. She gets along with Dia due to both being similar in their ways of being slightly dainty. 

 She definitely isn't be a strong fighter despite being merged with two mythical Pokémon, and would most likely depend on the others if she got herself in trouble.
