*Updated character info*
I see you've made a few changes. It's a lot better but I'm sorry to say it still feels a tad out of place and a few elements seem...odd.
...decapitated by a bulldozer that an evil jackal-like alien filled with scorpions...
Alright, I know I said it was sci-fi and all but this RP focuses on a futuristic but barren Earth. Aliens would probably have little reason to visit or even detect the planet and if they did, there'd be little we could do about it as transport technology has regressed massively and there's currently neither the knowledge nor resources to even send more satellites up into orbit, let alone deal with alien threats.
Not to say that aliens couldn't be involved later down the line but having to deal with them as well as the endless stream of issues simply surviving on Earth has...it's sort of derailing from the main focus.
Also, forgive me for saying this but that death is just...bizarre.
Abilities: Has a seemingly endless supply of throwing knives (usually picks up any pieces of metal he can find as he goes along and then shapes them into knives); is paraphenetic (Seems to be everywhere at once; is actually just quick-moving [However, does not have super-speed]); does not eat and drink like a normal anthro; instead, he photosynthesizes. (However, this process has caused his blood to turn green.) (He can photosynthesize due to a family trait that started when his father's father injected a plant serum into his bloodstream.)
Okay, this is an improvement although I'd probably say that you might have a few too many abilities and that they're pretty unusual/powerful, especially compared to what everybody else in the RP has. Still, I suppose this could work. The near-endless supply of knives is balanced out by the fact that throwing knives won't really have much effect against anyone except those without any armour or thugs whose armour has plenty of gaps. Throwing knives wouldn't have any real effect on any guards with even half-way decent equipment and soldiers, war androids, etc probably wouldn't even notice them hitting.
The "paraphenetic" thing seems a bit overpowered...you say it's not super speed, but anyone who's fast enough to appear to be "everywhere at once" pretty much counts as super speed to me. Sure it may not mean you can run in a straight line at the speed of sound or anything like that but it seems like you'd be fast enough to be near impossible to hit in combat scenarios...
Finally, with the photosynthesis...this is acceptable. Considering how much of the world has been ravaged by nuclear weaponry, the great damage to the environment, pollution, etc, this means that the sun is usually hidden behind clouds, smog, etc. I'm going to assume that your character's photosynthesis is far more efficient than any mere plant's version (otherwise even under constant sunlight you probably wouldn't have the strength to move). In this setting photosynthesis would likely mean that you'd have the most strength in areas outside the cities where there is no nuclear fallout to blot out the sun and in smaller cities which have less pollution.
Sorry to be such a pain about this and have you keep changing things but as it currently stands your character stands out like a sore thumb and certain elements seem to be overpowered whilst others are underpowered for the setting.
