While I'm not hyperfixating Hellaverse at the moment, I'm being into Antonblast. So, this is my fan character I've been brainstorming and sketching about: Tyra Misu.

Her character, color palettes as well as some of her jewelries wise, are HEAVILY inspired from Shokora from Wario Land 4, which I've been imagining her being a successor of Shokora.

While you have Annie as Anton's roommate, Tyra is his ex, though not in a bitter terms. They don't insult each other except bantering. Despite of their downfall, the two may rekindled their relationship, but it's going to be a slow burn. Additionally, Tyra still calls Anton by his nickname "Tony".
