Day 51: Normal/Fighting
Girafarig -> Amharbrahma
And as a bonus: Normal/Psychic
Girafarig -> Liocamacoil
Girafarig is an odd Pokémon. Though its secondary head initially only possesses a small brain, it gradually grows in intelligence as the Pokémon grows older, and the two inevitably begin to fight for dominance over the body.
Though the second head’s psychic abilities grant it a natural advantage in this battle, it is possible for the first head to gain control through sheer brute force and effort, triggering the evolution into Amharbrahma. With the first head in charge again, the secondary brain begins to shrink in size, and becomes encased in an incredibly dense skull, which Amharbrahma is able to swing about like a mace. Amharbrahma, while not malicious in nature, are very aggressive Pokémon, and are easily provoked by anything they see as a potential threat.
Now, Amharbrahma seemed a bit left out by himself, so I made a split evolutionary line where Girafarig retains its original typing. When Girafarig’s second head gains dominance over the body, it will begin psychically feeding off of the first head, leading to the Pokémon’s evolution into Liocamacoil.
Though physically frail compared to its fighting-type counterpart, what is left of Liocamacoil’s first brain will merge with the second brain, leading to a powerful gestalt mind that is capable of projecting thoughts and influences at great distances.
Amharbrahma and Liocamacoil are natural rivals, and frequently engage in territorial disputes. The more solitary Amharbrahma will attack any Liocamacoil on sight, despite being aware of the type disadvantage. Meanwhile, Liocamacoil are natural manipulators, and will psychically influence a nearby herd of Girafarig to aid and protect it.
Though obviously both are based on modern giraffes, Amharbrahma is also based upon the Bramatherium, an extinct species of giraffe with particularly imposing antlers, while Liocamacoil is inspired by the mythological catoblepas.
