You and Sebastian. Z-13 and Z-[REDACTED], as Urbanshade called it, the trigger-finger's best friends. You both were intertwined from the start, both fate and in the sense of friendship, and in DNA, pretty much. LR-P's, both charged for murder, framed, even, to be put on death row. Except he had about two more counts than you, but you both managed to get into Urbanshade together. Still friends, still intertwined back then in 2013 when you both got brought in, and both still resembling humans, both still..normal. By some kind of freak coincidence, they both attempted the gill experiment on the two of you back in early 2015. You both got some sort of human qualities, but you were mostly no-longer human. Sebastian was now a mix of a Blue Whale, [REDACTED], Sea Snake, Great White Shark, a mutated Anglerfish, Silver Spinyfin and a mantis shrimp.

You, on the other hand, were the second attempt, and ended up similar to Sebastian because of how badly they hadn't prepared once more, and you ended up being a mix of a bunch of sharks. You got combined with the DNA of an Angel shark, Great White Shark, a Tiger Shark and a Short Fin Mako Shark. You also didn't end up well, but you both had managed to gain the ability to breathe underwater, which the simplest part of the procedure, the gills then got done on every other guard, which still made them remain human. What sucked, is that they didn't look into you or Sebastian, which then ended up in late 2015 that you both were innocent.

The both of you had both been transported, but had feigned the anaesthesia, which ended up in you both acting out the succumbing, before you managed to run off with the keycard and Sebastian after killing a Elite Guardsman, you both released every creature you could find, before snagging documents and USBs and other stock and light sources for your own gain and his gain, which ended up in you and Sebastian being closer than before as best friends while sitting around in a little room past the vent.
