Life isn't going too well for you at the moment- a few years ago your sister was sent to a prison planet in one of the galaxys most well know prison ships-the vortex rikers-known for carrying some of the most dangerous and phychopathic murderers known, for a crime she didn't even commit (the whole day the thing happend she was with you all the time), of course you'd like to get your revenge on the bastard that framed her but there have been no trails so far but if you find anything then they had better start getting worried, but seeing as it happend so long ago you'll probably never find them out.
EVEN WORSE the ship crashed on a recently discovered planet and there was apparently only 1 survivor even though they were never found..... Even if they survived the crash the planet was completly infested by a race of reptile like aliens known as the "skaarj" who had enslaved a race of four-armed aliens known as the "nali" and were mining a mineral known as "tirydium" (that the planet had a lot of) that can be used for all kinds of things even though it is mostly used for power genarators,and the planet was so infested at that time that the chances of surviving would be about 1/100,000,000 for a "normal" human, but then, your sister and you aren't "normal" humans-when the planet was discovered it was found the skaarj had colonised quite a few planets and a war between the humans and skaarj began, earth would have most definately lost if it wasn't for a group of near superhumans who had all kinds of "weird" abilities-they can't feel pain even though their nerves are working perfectly, even if they are weak they can be hit from something that would be fatal to a "normal" human several times before getting killed, and they can take several gunshot wounds, although quite a few weapons still kill them if they hit right, they also never bleed and cannot seem to break bones, they also seem to have natural weapon skills and even if they have never touched a gun before they can use it as if they have been practicing for several years with it and could shoot moving targets from a long way away first shot, and although they can suffer from fear it is far less than a "normal" human might although this can make them a little over-confident at times, and they never get tired or fatigued even if their carbohydrate and fat reserves have completly run out, they are also resistant to "disablers" like tranquilisers and don't seem to catch deadly diseases (they get a cold or two and a few other minor diseases and illneses),the "powers" they have do seem to "fade" when they die though as in the last few seconds of "saviors" who have died painfully they are screaming like a "normal" human. All of these things allowed them to beat back the skaarj even though they also seemed to have quite a few of these "attributes" because of this the "condition" is called "savior" because they saved the earth from the skaarj in the war. And your sister and you both are "saviors" even if she didn't fight in the war and with that she had a fair chance of surviving the crash and escaping the planet, at around the time the vortex rikers crashed a spaceship from the planet apparently destroyed the bodega bay-one of the galaxys best ships, more proof that the survivor escaped the planet.
Things are looking up though as firstly you are the tournament champion, when the tournament started hundreds of years ago genes from a "savior" (which was unnamed at that time) were used to make the battles more exciting (it wouldn't be much fun watching people screaming in agony on the floor from pain would it?), even though contestants had most of your immuities in battle (the abilities only worked if an "aura" was set up around the arenas using a special genarator) they seem to lack your natural weapon skill which made you still more skilled than them.
a "savior" who was sent to na pali recently on a mission (which is what the nali's seem to call there planet even though some say it's just the name of a certain town on a bizzare floating island of which there are several above the planet) came back saying the skaarj had completly infested the planet again, luckily lately the nali have started using weapons themselves and also seem to have the immunites of a "savior", lastly a race that befriended the humans after finding out more about them after the survivor on na pali completly cleared out one of their ships simply call themselves "mercenaries" and they always wear special "combat suits" they designed that make them ALSO have a lot of a "saviors" immuities, none of these 2 races beat a plain human "savior" in strength and skill though.
