The Jack Bros. are duo competitors in the King for Another Day Tournament. The duo consists of Jack Frost and Mothman from the Megami Tensei series and its numerous spin-off games such as the Persona series, with their naming being based off of the Jack Bros. video game. They were added in as a unique fan submission.
- "He may be small, he may melt under even the slightest bit of heat, and he may ho, but Jack Frost sure isn’t going to melt under this pressure. Armed with some weak Bufu skills, his pal Mothman’s piercing gaze, and just a couple of Life Stones to their names, they’re ready to give this contest a shot. Today the Shinjuku underground, tomorrow the world!"
- —Jack Bros.' description on the MOJO!!
