The "Bad Guys"

Slendermane and Slenderman (Left): The Slenders are a duo of unknown creatures without faces. Both possess the ability to teleport and create static in any electronic they come near. The are said to be demons from pergatory, but their mythos goes much farther back than anyone can truly recall. They are ancient and dangerous, with an unknown goal.

Jeff the Killer (Center): Jeff is a psychopathic human who killed his family and disfigured his own face to be "beautiful". He has a bloodlust that can only be satisfied for small periods of time before he must kill again. He is insane, and can rarely be reasoned with. He may or may not even know why he likes killing so much. Either way, he is a threat that you want to avoid.

The Reborn Holder of Salvation (Immediate Right, Background): The Holder of Salvation possessed the body of LeonidasTheEevee's friend, Nightshade "Creepony" Slasher. This killed Nightshade, and allowed The Holder of Salvation to be reborn. Even as a pony, she still possesses vast amounts of power. She yearns for a reunion with the other 538 Holders to bring about the End Days.

Pinkamena Diane Pie (Far Right): Pinkamena is the other personality of Pinkie Pie. She is a murderer who captures ponies (or humans) and brutally tortures them until they die, before turning their bodies into cupcakes and clothes. She is sadistic, and evil, having no remorse no matter who she kills, at least until she reverts back to her Pinkie Pie persona. A classic case of Jekyl and Hide, but much much darker.
