octavia can manipulate kinetic energy (sorta similar to gambit from x-men's powers) which also allows her to absorb kinetic energy giving her superhuman strength and speed (although that's temporary). she was experimented on from birth to fourteen at biogen, a biotech company that did a lot of off the books genetic engineering. but she worked with a bunch of former subjects to take down the company a few years back. she dabbled in being a superhero for a bit but after losing her fiance, she gave up on that and now works as an assassin for hire.
