According to a recent study by Professor Cedar, Vaporeon has the capability undergo variant evolutions tied to its environment.
This is speculated to be due to the highly volatile nature of Eevee DNA and the evolutionary tactic of extreme adaptability all Eevee possess. To adapt expertly to climate and environment upon evolution, the pre-evolution Eevee will adopt aspects of other residing species of pokemon, ensuring an incredibly high survival rate.
The standard Vaporeon variant occurs if the Eevee has not resided in a particular environment for an extended time, or in heavily populated human city centres.
he… his name is Hyloscirtus hillisi! He’s from the Andes!
According to a study published in the journal ZooKeys, the amphibian has dark brown skin dotted with orange flecks and features a large and unusual claw-like structure protruding from the base of its thumb, known as a prepollex.
At present, it’s not clear what the purpose of this prepollex—which is essentially an undeveloped digit—could be. However, the team of researchers who discovered the frog—led by biologist Santiago Ron from Pontificia Universidad Católica del Ecuador—suggest it could be used to defend against predators, or wielded as a weapon to fight other individuals of the same species (for example, when males compete for mates).
