The Symbiotes, also know as Alien Symbiotes or Living Costumes, are an Sapient species of amorphous parasites which must physically bond to other organisms in order to survive.

Temperament and Needs
Symbiotes are a naturally violent species, giving way to murderous urges on a regular basis, causing them and their hosts they may be bonded to to be considered extremely deadly adversaries to contend with. This bloodlust seems to delve into the physical need, as well, as the symbiotes will sometimes feed upon their hosts to sate their lust for blood, feeding on organs including but likely not limited to brains and spleens. This is apparently due to their requiring the chemical phenethylamine in order to stay both healthy and sane, which is found abundantly in two sources on the planet Earth: chocolate and human brain tissue. This seems to cause the host to be forced to either buy or steal large amounts of chocolate or become an unwilling cannibal that devours the brains of its kills.

Reproduction
Their species reproduce asexually, budding off suddenly into a second symbiote when they've consumed enough "nutrition". However, a symbiote will immediately forget its offspring since they naturally will have nothing to do with one another from that point forward.

Weaknesses
While Symbiotes are incredibly powerful organisms which are nearly impossible for a host to remove without aid of any sort, they are subject to a multitude of natural weaknesses. These include sensitivity to intense sound and heat (especially large firs), and are weakened by magnesium. They have also been found to be vulnerable to the heat produced by high-voltage electricity. Other weaknesses include chemical inhibitors, the lethal touch of a criminal named Styx, advanced healing factors, and an antidote formula developed by Tony Stark that was a viral organism based upon the Symbiotes by Doctor Doom as a biological weapon.

Evolution
Unfortunately for other species involved, with each new offspring created their species evolves, not only increasing the strengths but also reducing their sensitivity to weaknesses. In inclusion to this is that already existing Symbiotes may one day mutate and develop resistances or even immunities to weaknesses that they formerly were subject to. Luckily, however, immunity to weaknesses seems to be extremely rare.

Racial Abilities
Symbiotes feed on adrenaline, and in exchange they offer their hosts various powers that generally include enhanced strength, speed, and reflexes. In order to provide this, however, the symbiote must cover its host with itself, effectively forming a full-body suit. Symbiotes also appear to extract the DNA of their hosts, and modifying their own DNA in the process; this would explain how they obtain the powers of superhuman organisms simply by attaching to them Other powers known to be garnered from being bonded to a symbiote include the ability for transformation and mass-alteration.
