And you thought post-apocalyptic Hoofington was doomed before.
There's an idiom in Japan: "Like giving a Kanabo to an Oni". It means to give the upper hand to something - or someone - that already has every advantage. For reference, an Oni is a mountain-dwelling ogre in a leopard-skin loincloth who can pummel your brains into soup with their bare hands. A Kanabo is like a giant, studded baseball bat made from iron. You can probably guess what happens when you introduce one to the other.
I had a funny idea a couple days ago. I was like "The Reapers were named after a Hoofball team, so wouldn't it be cool if Blackjack had armor with the number 21 in varsity-style block numerals and a helmet that looks like what would happen if you crossed a football helmet with a samurai helmet, maybe with a little T-45d and Casshern on the side?"
Before I knew it, I was possessed to draw this: Blackjack in custom power armor made from salvaged Enclave tech by Rover, Silver Stripe and the Collegiate, primarily for data-gathering purposes using onboard telemetry.
Perhaps the Zodiacs were sick of failing harder than Team Rocket, so they wanted to learn the secret to Blackjack's "success" by recording her every move, or maybe even use the data to engineer better power armor for themselves. Yeah, I can see it now. P-21 would probably complain about Blackjack stealing his number, and she'd say it was some Zodiac who thought they were being clever and painted it on there.
The suit has vectored Maneuvering/Descent thrusters (nope, no flying around like a Pegasus with this thing; the wearer and suit are about ~600 pounds put together, and the rockets put out a little bit less than that), retractable climbing spikes and a compressed-gas grappling hook launcher with motorized winch.
The vectored thrusters provide small bursts of speed in any direction, for evading incoming heavy ordnance or charging directly into the fray. Using arcane technology, they automatically re-orient themselves to compensate for the wearer's movements, and can be activated with a mere thought by synchronizing with the wearer's cybernetics.
The climbing spikes, grappling hook launcher and winch are good for rappelling down from heights, vaulting over barricades and scaling steel-reinforced concrete walls, tenement buildings and cliff faces (or maybe even breaching the walls of Hoofington's core, though she'd have to be prepared to run like hell). The climbing spikes can also be used as ad-hoc stabbing weapons, and pivot out of the way so as not to hamper mobility; they are controlled mentally via the wearer's implants in a similar fashion to an additional set of "fingers".
Should she fall and reach terminal velocity, the thrusters and airbrakes will bring her to a soft landing. If they have enough fuel remaining, that is. Only 30 seconds of burn time in the tank, and it takes at least 1 hour to get back up to full by using special kidney implants to distill a potent monopropellant rocket fuel from gemstone essences and alcohol in the wearer's bloodstream. The higher her blood alcohol level gets, the faster it regenerates.
Before you ask, this armor and the "story" behind it are totally 100% non-canonical. Just for fun, in other words.
