John used to sport a sleek, slightly side-swept black hairstyle that hints at a brooding, almost emo edge. His deep black eyes glow with vivid red irises. A black bunny-shaped badge, embedded in a golden ring, adorns his right pointer finger, a small but iconic mark of his identity. Broad shoulders and sculpted arms showcase his incredible strength, while his toned abs speak to years of discipline and physical prowess. Black nail polish and matching earrings complement his dark aesthetic. He dresses in a black zip-up hoodie with bunny ears and red accents, layered over a gray shirt and paired with black pants and a subtle bunny tail. His black shoes feature red Velcro accents, completing a look that is both practical and expressive. His sharp jaw houses white, well-kept bunny teeth, completing his distinctive appearance. But now John's core is all that remains of him, it appears as a heavy, blackened and charred rock, with glowing cracks of magma running through its surface. A distinct impact mark mars the stone. The deep indentation of William's claw remains embedded in the core, including a clear impression of his thumb where he crushed it.
