Description: a regular black Umbreon with regular eyes and rings. The rings glow like all Umbreon. He has an extra move in Shadow Claw and happens to have a Future Sight ability that makes him unlike any other Umbreon or Eevee. 

Personality: a friendly and helpful Pokemon who is quite eccentric and quirky in how he deals with issues. Eon has a tendency to be flirty with Vulpix and Ninetales and tends to hang around those he considers allies such as Frisk and Churro. He can sometimes be dumb, but half the time he fakes it because it makes others happy. He is a very joyful Pokémon who usually doesn't let others get him down. His smartness is usually hidden, yet his ability to predict the future is unlike other Pokémon. 

Status: Dead (killed by Kagis) 

Goals: to protect Churro (succeeded), to protect Arceus (succeeded), to help the Starter Squad (succeeded in some way), Help Frisk take down Pulse's ghost (succeeded)

Allies: The Starter Squad, Neri, Ruri, Jedi, Boyfriend, Girlfriend,Frisk, Majnun, Fae, Zappy, Zen, Lazarus, and more

Enemies: Skliros, Pulse, Luxray ( I forgot if I gave him a name)

History:Eon was born to a Jolteon mother, not knowing his father. He was born in a place where Eevee are sold to people for profit. When he was old enough, he was adopted by a human and gets to leave the place. Unfortunately, tragedy strikes and a villainous human and Luxio duo kills most other Eevee in the building including every sibling he's ever known of his litter. The only Eevee who survived the attack was his younger sister, Fae. His mother also survived the attack. This was when he was six and Fae was four. When he was ten, he left his human owner to live in the wild after having a vision of it. He has a vision of a Treecko about to die and searches out for him, finding he's just in time and rescues him. When he gets a vision of Arceus falling, he sets out to rescue them too, managing to convince Tudi and friends to abandon Skliros. He has major beef with Skliros and the Luxray for their missions against the Starter Squad, world, and against him personally. When he was fifteen, he found his step-sister, Neri and managed to get her away from their crazy family. When he was seventeen he began to journey with his actual sister, Fae. They journeyed together until Skliros tried to plot Eon's demise, instead killing Fae and controlling Zen and Lazarus, two legendary wolves, into trying to kill him because he knew of the Pokémon's ability to Future Sight. Despite losing his sister, Eon still trudges on. He holds on to Neri and her mate, Jedi. Over the years Eon has met Ruri and is good friends with her, learning about the Pokemon he had killed to help Pip. Ruri and her team (I forgot the Gengar and Lillipup's names, but I know they're important for Ruri's success) oftentimes can be seen with Eon as he journeys outside of Poketown, helping him with taking care of and finding new members for the squad as well as finding possible humans from other worlds. When Eon is in Poketown, he is often seen with Churro or talking with Pip. Pip doesn't seem to like him much, but he does talk to him on occasion. However one day, Eon is faced with a choice. The choice to follow the destiny his Future Sight gave him or to save himself and risk the lives of the Pokémon he loves. Choosing the first choice, Eon comes back to Poketown to help save Churro, and Frisk, one last time, shielding Churro from a surprise enemy, Pulse in the form of a starter squad member, Kagis. 

Age: 38 in human years (as of the FNF and Pokemon crossover)

Main story: Visionary Darkness

Note: the scarf on Eon is made by Pearlyarts. Didn't feel good just taking something with a watermark and just deleting the watermark without telling you where it came from. And yes I did warn you about the spoilers. So uh yay! I'm telling you I'm killing all the dark types apparently. If I had a nickel for every dark type I killed I have two; which isn't much, but it's shocking it happened twice. funnily enough the longest living Pokemon might be actually a dark type as well.
