Mantle Murinae
 

Mantle is a 22-year-old anthropomorphic mouse and a petty, cowardly rival to RaFF, running his own competing tech repair shop. Small in stature and even smaller in confidence, he’s obsessed with one goal: ruining RaFF’s reputation. Inspired by rivalries like Thatherton from King of The Hill, Mantle brings comedic tension and chaos to the story—but beneath the bitterness lies a wounded kid who was never seen. Overshadowed not by his brother, but by a father who refused to acknowledge him, Mantle projects his unresolved pain onto everyone around him. Over time, his role shifts from petty antagonist to someone in need of forgiveness—delivering both humor and heart in his eventual arc.
