A genuinely tragic, lonely, and sympathetic character, Dark Princess spends most of her time scheming revenge on Ooo, in hopes of someday ruling over Ooo. Dark Princess only thinks about herself and when she is being nice to others it is only to use them, she thinks love is weakness this being the reason for her loneliness. She will try to silence anyone in her way, especially her archenemies Marsha and Marceline. Dark Princess is pure evil. Despite doing mostly bad things, it can be said that she hates anyone who's good.

Skills
Dark Princess can create dark matter balls that can harm her enemies. She can also impersonate other, for example, Marceline so she could destroy Finn's love for her. She is just as skilled as Marsha when it comes to teleportation. Her magic arua glows a pitch black, in comparioson to Marsha, which is a bright pink. She can summon a black hole that is actually a portal but can do serious damage if someone steps on it.

Parents
DP's parents were both alive when she was very little. Her father gave her the magic tiara she normally wears. Her mother was taken away from her, which made her change. She began becoming evil, which her father liked.

One day, Hunson Abadeer killed her father because he killed his wife, Rose Abadeer and nearly went after his youngest daughter, Marsha. From that day, she seeked revenge on Hunson by killing his daughters, Marsha and Marceline.

Marsha
She constantly bullied Marsha in the past, especially when Marsha was a "blank-flank". Even with her cutie mark, Dark Princess bullies Marsha during the present day.
