This one's somewhat boring for me:
1) I graze upon the savannah, waving my tail languidly, as the midday sun shines upon my stripes. Human concerns are not mine, as I'm both a zebra, and tranquil to boot.
2) As my 'setting' is reality as we know it, I still do as described above.
I could of course assume that the avatar picture is the true face under the helmet of my E.Ψ.E: Divine Cybermancy character, the last faceless game character I named Tranquil Zebra, as I have a habit of picturing those as zebras under the mask.
1) I would probably break the sofa I'm sitting on, as I'm in medium armour and the ground shakes when I jump. I would then convince my parents that yes, I'm really me. Then I would try to sort out this whole mess with the government, turning over my sniper rifle and .50 hand cannons. And my grenades. And my default katana. Luckily, I study at the best sciencey university in the country, which is honestly one of the premier in the world. NTNU's Medical Cybernetics programme, and its professors, would probably jump at the chance of studying a genuine zebra supersoldier with drastically increased physical capabilities. The Africa Studies programme probably would as well, but that's less relevant. I would then be studied, advancing medical and military science i particular. I would probably join the firefighters or something now and then, seeing as I'm only really vulnerable to anti vehicle and above weaponry, thanks to the environmentally sealed armour I'm wearing. Seeing as I'm functionally immortal, but would respawn in the hub area of E.Ψ.E, I would probably come around to scenario number 2 anyway, sooner or later.
2) I would probably wonder why I removed my previous memories and left cryptic messages to myself, and then proceeded to kill my mentor (canon in E.Ψ.E), in addition to creating an elaborate fantasy where I was a 20 year old university student from before First Contact, transhumanism and psionics (my self-insertion). I would then be a good soldier, trusting myself and my commander above the mentor, and fight against anarchists, an oppressive regime and the Metastreumonic Force, whatever that last one really is. Since the game starts just after you brainwashed yourself, a self insert fits right in as a last minute addition your previous self made up. I haven't really played too much of the game, so what is yet to come remains a mystery.
