As the monstrous Valkyrie X, she's a mechanical tank with a green body, and a greyish blue eye and caterpillar treads.
Her true self Valkyrie Horton has auburn hair that reaches her waist, green eyes and (likely due to being poisoned) pale purple skin. She wears a black dress with what appears to be a black bodysuit and over her mouth and nose is some kind of mask. Like several characters in the game, she is unable to see Life Capsules.
Valkyrie was kidnapped by Ciel Sorcière and taken to the castle where the Castle Master was. This led to her husband, Evan O'Neill, going to the castle to save her; this eventually ended up in his death at the hands of the Castle Master himself.
While Serenity Horton is traveling through the Servant Quarters, a mechanical being called "Valkyrie X" attacked. Upon defeating it, it's actually revealed that Valkyrie X was Serenity's mother all along. She was in a lot of pain, having been poisoned for almost two years by the Castle Master and was also made immortal through a spell, though only those of Valkyrie's blood - such as her daughter, Serenity - could kill her. Serenity tries to reason with her and is forced to kill her, and gains the Valkyrie Wings as a result. After that, her quest to defeat the Castle Master becomes personal.
- Her first form, Valkyrie X is a giant tank and a palette swap of Monster X.
- The fight with Valkyrie is the only one where the boss doesn't fight back at all. If anything, the player is forced to kill her themselves instead of doing so in a cutscene.
- Valerie Horton's spritesheet has enemies and npcs (who tell you about Valkyrie X). Valerie has no attacks because she doesn't fight back.
