It is inspired greatly by Sadist's "Ozymandias", especially the pose at the eye scene that I, ahem, "accidentally", unintentionally stole.

I PRESENT TO YOU, OZYMANDIAS DRAWN BY ME.
THE CHARACTERS ARE MINE (that are shown in video)
Characters, backstory, prophecy stuff and color meanings can be found below the video.

[There should be a GIF or video here. Update the app now to see it.]

This is kind of like the fake BrambleStar scenario, but instead TigerStar taking over SquirrelThroat. BlueStar feels the need to redo her failure in the FireHeart era to defeat TigerStar once and for all when he is in the dark forest, and possesses SootStar, then possesses SunSpark later.

Characters

SquirrelThroat: the dark blue Tom
Smolder: old cat at the very start and end. Deputy of the Wanderers
SunSpark: red cat
SootStar: dude on the ground, you might figure out who she is if you read the Backstory.
NightEar: cat with heart on one of the pounds, crying. SquirrelThroat's past mate, her emotions warped into something he wants, believing he needs her dearly and convinced he will sacrifice himself otherwise.

Backstory:

BurrowClan ( or Guinea Pig Clan ) is a clan that is full of caustic, popular wanna-be cats.
They believe that the more achievements and the more well-known and respected you are, the more you will be remembered and bowed to. (They bow to the StarClan cats that are familiar and 'great' to them, like actors or something)
THEY DO NOT KNOW THAT THE DARK FOREST EXISTS; THEY ARE A REASONABLY NEW CLAN.
The frame of all of the past, dead leaders are deputies too.

SquirrelThroat is the cat that decides that it would be MUCH easier to be recognized by one big, morally wrong act then hundreds of a lifetimes worth of good acts. Soon after he makes a plan to begin this he gets possessed by TigerStar, a vengeful spirit from Into The Wild. He is not my OC.

After he gets kicked out for killing the deputy (not shown) because he wanted to take the deputies place and Sunkit saw it in 4K, he meets a group of starved cats who labeled themselves The Wanderers. They said how they don't know how to hunt and that BurrowClan is stealing all of their food, so SquirrelThroat offers them a chance at food in return for being their 'leader', per say. Their leader agrees.

Soon they had killed SootStar and taken over BurrowClan (though some revolted), and moons pass of luxury and near slavery.
Sunkit soon becomes SunSpark (prophecy stuff I don't want to explain), and leads a kitty revolution against SquirrelThroat. They run away and soon a great battle occurs. Sun' and Squirrel' battle it out and Sun' wins. NightEar cries over a lost mate, but joins the new, improved clan.

The prophecy:

It was a dream SootStar had and BlackStripe tried to decipher it.
Basically a tiger-thing of blackness grips a squirrel with red eyes, looking back at Soot'. The squirrel began to burn up, one side blue flames and one side red. It flashes to a dead squirrel on the ground, smiling.

The squirrel is SquirrelThroat, and the tiger is supposed to represent TigerStar's control/influence over him.
The blue and red flames:
TigerStar is the red flames.
BlueStar is the blue flames.
BUT  it could also be seen as SunSpark being the red fighting SquirrelThroat the blue, for Burrowclan's perspective.

The squirrel burning up shows how Blue' and Tiger' both destroyed SquirrelThroat, in a sense. Him smiling shows how he fell and went to the dark forest, but he was smiling and glad to be in the dark forest, showing how it was not entirely Tiger's influence making him 'evil'.

The colors

Dark blue: representing SquirrelThroat, and every other thing blue showing what he caused (blood stains of the cats he killed, tears from a cat, etc.)
Brown: brown squirrel. It's a brown squirrel -
...
It signifies, um food, I guess. If you didn't get that I swear-

Red:in the prophecy, signifying SunSpark. Also showing how he sees her as, like, the 'enemy', per se. because red is usually the stereotypical evil color.

Eyes: Squirrel's empty, dead eyes signify, um, him not going to StarClan? Idk it looked cool.
SunSpark's eyes represented how 'fire-y' she was, like in the prophecy.

Hope you enjoyed! ^^
