No force can stop a rampaging Saddle Rager, not even a blast of antimatter can take that deus ex machina down. But Yellowbelly doesn’t use force, her meek appearance and pitiful demeanor are enough to make most fighters hesitate to strike, but a glance into those deep black eyes is enough to get even the most furious foes to momentarily question their actions. And that brief moment is enough to revert Saddle Rager back to her normal self, making it easy for others to take her down.
 
Yellowbelly plays more of a support role, as a distraction or wildcard, but her real strength is in her talent in manipulating others. Though she tends to be mistreated by her teammates, anyone who takes pity on her will find that she’s no less evil than them. She’ll take full advantage of anyone offering help, while acting helpless and innocent enough to keep them questioning.
 
She has a swan shaped headpiece because they look nice and graceful from afar, but become terrifying at close inspection.
