Best described as an 18th century naval revolver cannon repurposed as a jetpack, the Revenge has six revolving chambers in which to load various types of cannonballs. Each chamber is marked by color (red for fire, blue for ice etc.) and can hold a few cannonballs each before needing to be reloaded.

While this is obviously all fine and dandy, the Revenge has a hidden functionality you wouldn't guess until you've seen it in action, because you'd swear it was invented by a mad person. By taking the mounted rig normally used to carry the cannon minigun-style and slipping it over her shoulders, Bonny points the cannon at the ground, fires, and takes off like she's wearing a jetpack, dropping bombs on her enemies from the sky. This is not actual flight but rather a sort of rocket jumping, and Bonny rises and falls in a predictable parabolic arc when using it.

Additionally, the cannon can also be used as a handy bludgeon or battering ram in close quarters combat.

When Bonny repurposed her father's cannon into her own weapon, she realized the new revolver mechanism made the traditional rammer used to load cannonballs into the breach obsolete. Not wanting to get rid of such a fine piece of craftmanship, Bonny wrapped the rammer in cloth infused with fire-elememted Dust, creating a giant, reusable match. Now whenever Bonny wants to set something or someone on fire, she just strikes the rammer on the ground like a match, takes a swig of whatever's in her flask, and sprays it all over her makeshift torch, blowing fire everywhere like a carnival firespitter. She does this both because it's fun and because her cannon makes for an effective yet unwieldly melee weapon. This way, she can be quicker on the draw and avoid risking any damage to her main weapon.

Bonny's Semblance allows her to detect minute changes in electromagnetic fields with great sensitivity, much like a shark's ampullae of Lorenzini. She can sense muscle contractions in people and animals, which many people mistake for a psychic ability or having eyes in the back of her head. Due to this ability it is very difficult to hide from Bonny, and almost impossible to get the drop on her, as her Semblance allows her to "see" you move faster than normal eyes could process. It's also how she knows where to hit you from behind cover, and why she always greets people before they enter the room, something she likes to do just to freak people out.

Bonny uses Dust ammunition in her cannon, launching cannonballs of various elemental types through the different chambers. Using fire Dust or explosives as a powder charge, she can also fire the cannon at the ground and use it like a jetpack to rocket jump. These cannonballs can also be tossed like bombs.

The types of elemental dust Bonny uses in her cannon are Fire, Ice, and Electricity. She also uses explosive and smoke cannonballs.

A shark Faunus, and also secretly the daughter of the now infamous Faunus pirate Woodrow "Woody" Thatcher. Born to Woody and a human mother, Bonny and her family lived happily as a shining example of mixed-race marriage. For about two years, after which Bonny's mother was killed during a supposed "White Fang suppression" effort while defending her husband and child, a campaign that saw Bonny's hometown destroyed, burned to the ground, and Bonny and her father imprisoned with other Faunus refugees in the internment camp "Menagerie". They made a serious mistake in underestimating the depth and fire of the aquatic Faunus' rage however, and Thatcher soon conspired to escape from Menagerie with his daughter and a small group of like-minded men in tow. It was this group of escapees that would come to form the founding members of Woody "Dust to Dust" Thatcher's less than jolly crew of pirates, a mercenary group that sailed the high seas for years freeing Faunus and pillaging from the rich. Stealing a boat from the docks of lush human city just outside the borders of Menagerie, Thatcher put what little he knew about maritime protocols to use, and set sail a new and freed man.

At first, during the early years, they just took on jobs for disenfranchised Faunus, only striking out at Remnant's oppressive governments when provoked... or when given the chance. It was these years that Bonny would come to remember as the golden ones, where she as a young girl truly felt as free and guiltless as the pirates her father read to her about in story books. But this wasn't Neverland, and she couldn't stay a kid forever.

As time went on, the jobs Thatcher's crew took on became increasingly violent, fueled by the bitterness and hatred of the oppressed Faunus and her father, who never truly got over the loss of his wife. Their pillaging became more frequent, targeting not just rich government officials, but any human towns they could find. Villages burned. People died. Innocent people. Her father cited the needs of an always growing crew, but Bonny knew better. She knew her father and the crew were striking back because they hated humans, because they couldn't forgive in their hearts the things they had done to them. And their violent acts of rebellion were only growing worse. Bonny watched as the illusion that had carefully protected her through childhood crumbled, and her father's crew became monsters to her.

Though she knew what they were doing was wrong, Bonny had tasted enough of human cruelty that she was still indecisive, unable to agree with her father but equally unable to invision a life for herself outside of the crew. Unable to forgive the hatred that was in her own heart, the hatred imparted to her by her father. That all changed the day her father began planning the siege.

It was the largest operation the crew had attempted to date, and it would see them returning to the coast where they had first escaped from Menagerie. The plan was simple. Create as much chaos and destruction as physically possible to draw attention and manpower away from the borders of Menagerie. Then, a small group of men from Thatcher's crew would infiltrate Menagerie and start a riot, breaching the walls and defenses of the prison with a flood of angry Faunus that would cascade into the city, creating even more damage and senseless violence. Then, once the chaos became self-sustaining, the crew would pull out, leaving the city and its human inhabitants to their fate.

The sheer horrificness of the plan, not to mention its size and scope, shocked Bonny out of any illusions she had that her father was not a criminal, and she began plotting mutiny. The night before the siege was scheduled to begin, Bonny smashed all the bottles of rum and spirits aboard the ship and set it ablaze, ripping the ship's ornate main cannon off the bow and swimming out to sea with it. If all went well, she'd make landfall in a few hours. More than enough time to warn the city before her father got the fire under control.

All did not go well.

Her father caught wind of her betrayal, and as she set off towards shore with the cannon in tow, her father shot at her in rage, puncturing a hole in her dorsal fin near the base that made it almost impossible for Bonny to swim carrying the giant cannon. However she persisted anyway, and disappeared into the night.

The damage to her fin proved greater than she'd imagined, and it left her unable to stabilize. Eventually she veered far off course, losing time and gaining miles until eventually she ended up on the shores of Atlas, half dead from starvation, exhaustion, and blood loss. She had just about torn her fin off trying to make it to shore with the cannon, and by the time she made it, the siege was already over. Miles and miles down the coast, the defenseless city had fallen, and Menagerie had been breached, causing the largest prison break of interned Faunus yet reported. To add insult to injury, her futile efforts cost Bonny her fin, and with it her hopes of ever swimming again.

Landlocked, out of hope and out of options, Bonny found her way out as a Huntress. Gaining an Atlas sponsorship for the combat skills she'd honed as part of a pirate crew, she fashioned herself a weapon out of her father's old cannon, eventually graduating from the preliminary combat schools and finding her way to Beacon as a transfer student, where she hoped/hopes to start a new life.
