Sonny Wong

A Paper Master employed by Dokusensha. He's mysterious, wearing sunglasses and a large coat that conceal most of his face, and he never speaks. He's incredibly physically strong as well and probably at least seven feet tall (given he is much taller than Maggie, who is six feet). He has no qualms about killing people to achieve his goals.

He challenges the Paper Sisters during "Twilight of the Papers" episodes and proves stronger than all three combined, even capable of ripping Maggie's familiars apart with his hands, and he only meets his fate after Maggie successfully manages to fight defensively until he is engulfed in a sea of ink released when a series of explosives in the building go off.
