Yoyo

British-American Monster Huntress, Yoyo Metalman. Daughter of the Metalman family, filthy rich and herculean feats throughout generations.

Although she was born into a wealthy life, she still sought to work her ass off by running her own independent Monster Hunting business, running around the country, hunting down monsters for cash across America. For this adventure, she obtained the perfect tool to help her: A shapeshifting hammer she bought online.

With a hammer able to grow as big as she can imagine, she easily smashes entire building-sized monsters with one swift motion (although the real challenge for her being smaller monsters, 2 meters or shorter).

She's joyful and whimsical, a little too happy for her line of work. She never lets anything ruin her naiveness, even managing to befriend some of the monsters she's hunted (secretly lusting over meeting a werewolf someday).
