WARNING; Mention of Murder & Cannibalism. Sabrina's birth started out normal as if every other birth of an irken child, however, her genetic makeup was very similar to Tak - because she was supposed to be an exact clone of her; but when she was broken free of her incubation tube, given a PAK, and "activated" - she was captured, and experimented on after coming in contact with Athier, a former resisty recruit, this resulting in her hybridism. Reason why they did is still totally unknown to this day, but this DNA caused her to grow a tail as she aged - and for her aggressiveness to boost, as well as her teeth being more pointed and jagged than normal irkens. This also allowed her to withstand the taste of blood and meat and add it to her naturally sugar-based diet. However, eating too much of it can very much sicken her. During her smeet-hood, Scientist Chadge, watched over her and studied how she grew and changed after this change in her genetic code. He was pretty much the fatherly figure for her growing up into adulthood. And Jade, before she became a Tallest, was pretty much her motherly figure. This change in her genetic makeup caused her to attack her own kind without hesitation, even attacking and almost killing other young irklings of her age. Around her teenage years, she joined other Irkens for tryouts. Instead of receiving the Invader class she yearned for; her PAK was programmed for the Spy class. Which at first she was sour about, but eventually she got over it and stuck with her original class. Spying on enemies turned out to be fun to learn their weaknesses. In which she was sent on spy missions. During her missions she met Invader Zado, who pretty much became her mission-partner. The two working together like peanut butter and jelly. Around their seventh mission, they came to planet Xunnarvis where they both encountered a pack of wild, hungry Lupuinaxes. Sabrina obviously felt the urge to challenge the alpha, which she did alone of course, which resulted in her scars on her body and the single scar on her eye. Zado eventually helped her defeat it (much to her dismay of wanting to face it alone) and rushed to her aid, to be concerned by her oddly colored blood, which wasn't it's usual translucent pink - nevertheless he cleaned her wounds and helped her back to their base on that same planet. After sometime, her aggressive behavior took over - and was eventually known to suddenly burst out in anger and attack other irkens without any warning. The cravings of meat would drive her wild, and the only way she got it was from killing unsuspecting irkens. Did she commit cannibalism? Yep. Murderer? If you put it that way, maybe on her own planet. But she wasn't very proud of it all. Her feral side just took over and drove her to kill. Still to this very day she is shunned about it, but no other irken knew about this - only her, cause the irken meat she ate was someone she had just killed. When she was an adult - months after the announcing of Impending Operation Doom 2 (meaning after Zim was already sent to Earth and already arrived there) - the Almighty Tallest got word of a strange irken lurking around. Still around this time they had no idea of her meat-eating past, finding her different - and short (but slightly taller than Zim) - they got the idea of sending her to this Earth planet to spy of Zim - or should we say to really stir up trouble for him - after Red and Purple realized she had no hesitation when it comes to attacking her own kind due to the Lupuinax Blood in her veins. The Tallest had eventually sent her to Earth to mess with Zim, and quite possibly to stir up trouble. Before she left to this new planet however, a pesky vrigmix was found stealing a donut from one of the bags - in which Red picked up and shoved into Sabrina's arms; telling her that instead of her getting her own SIR Unit, she'll be getting... This tiny.. Critter.. As an assistant. Though once on Earth (after crash landing), her and Zim became enemies at first (only on Zim's account) - after discovering her now-abandoned crashed cruiser he realized his "mission" could be in jeopardy especially after his encounter with Tak. He was sour at her for thinking she was there to steal his mission from him. Eventually after awhile and finding out she wasn't any of a threat they somewhat advanced into frenemies, then eventually friends (though Zim denies it out in public!) and slowly over time Sabrina realizes she has a liking to this other irken. Though, she likes to cover up her liking of Zim by semi-bullying him, which can range from anything from spraying him with water, dumping water buckets onto him, or tripping him into a puddle... Or by sticking as many writing utensils she can into his hairpiece/wig. Eventually, Zim got used to her company - even though it took quite awhile - however most of the time Sabrina disagrees with his really idiotic ideas for plans to take over Earth and sometimes even mocks/questions his authority. Though, now on Earth she is more "tame" and relaxed than she used to be on Irk. Her will to pretty much attack anything that moves has lessened greatly as she finally found a planet rich with actual meat to eat! Her favorite is this... Fish called a Salmon. She also very much enjoys the hell out of sashimi and sushi. Sometimes chicken liver is good too, yummy yummy meats. She's still very ashamed of her past due to the craving of meat driving her feral, any reminders of her past will cause her to break down into a sobbing mess who repeats the words "I'm sorry." over and over. She also built her own SIR Unit herself since like Tak, she too is capable of building machinery - she even designed her own cruiser! (Her Shade Cruiser/Runner) Though, she meets another irken in the dark forest she happens to live nearby, and saved him from two stalking hungry predators. After getting to safety, they told each other about themselves and eventually formed a friendship. Though, after awhile, hearing Rotimi confess his feelings (and fail at it) - she understood what he meant and was happy to find someone who she actually really loves. She is also very protective of him, but also extremely affectionate. Finally someone who doesn't yell and demand to feel honored 24/7.
