Sasha

New f***ing memes have arrived! Sasha, also known as the Memes Kid, is an inhabitant of Meme World.

Early life
Sasha was born in the country of Ukraine on Earth. Throughout his early childhood, Sasha's mother would frequently restrict his internet access, fearing that her son had grown addicted to memes. She was right. Sasha's addiction had grown to a point where if he did not get a frequent dose of memes, he would fly into a rage and break things. This behaviour brought him into conflict with his mother, who in turn imposed harsher restrictions on his computer. This led Sasha to run away from home in order to get the memes he needed. Somehow, he ended up on Meme World, where he found all the memes he could ever want and more.

The Dong Squad
When the Dong Squad was formed, Sasha followed their adventures through the news reports broadcasted by Tyrone and Rog Rogerson. He came to idolize the squad, and even sent fan mail to Lord Zrintch, hoping to get into contact with them. Sasha was ecstatic when he found out that they had arrived on Meme World, and when he learned that they were battling Tommy Wiseau for the fate of the universe, he knew what had to be done. Sasha grabbed a rocket launcher and met up with LeTrole Rusemann, King Harkinian, and the Reddit Alien to help the Dongers. They arrived in Wiseau's underground labyrinth to turn the tide when all hope seemed lost. Sasha fired his rocket launcher at Wiseau's bat-like steed, temporarily injuring it and providing the Dongers with an opportunity to fight back. He also threw several CDs at the creature, but these had no effect.

Tommy Wiseau soon teleported himself and the five still-conscious members of the Dong Squad away into a reality warping chamber, leaving Sasha and the others behind. Sasha was upset that he could no longer help his idols, and threw a tantrum. Fortunately, his anger subsided when Wiseau reappeared, and was defeated by BONES on top of a nearby volcano. He later attended the funeral of Yon and the other deceased Dongers.

Origin of Meme
In The Mazkertis Paradox, it was revealed exactly how Sasha gets his regular dose of memes. When Soldier and Billy Mays exited the Dongers' ship for a breath of fresh air, they witnessed Snoo, the "Reddit Alien", regurgitate old, cancerous memes into Sasha's waiting mouth. The two Dongers were both equally disgusted by this, so they ran over to Snoo and beat him into the ground while Sasha looked helplessly on.
