Hydra is Hydro's daughter. He adopted her in October of 2019 when she was 13 years old after seeing her dominating other players at Super Street Fighter II Turbo on Coney Island. He promised her sugary drinks, savory snacks, and any amount of time she wanted to game. Nothing is known about her life before.

She has a preternatural talent for video games enhanced by years of nonstop practice. Her abilities span all genres and eras of games. She often travels to attend tournaments or consult for studios on game development, though she only plays money matches at the hotels and declines being included in credits because she dislikes attention.

She doesn't contribute to or watch Hydro's stream. She has said she doesn't understand why people do. She is rather toxic.

In the way that family pets are often called one person's pet, The Dark Lord is her cat.
