For Raven's contest. I am sorry for tha late bio, but I had to run last night and could upload just the pic. Now, here's Rukrash's bio:

Lenght: 200 meters
Height: at shoulder, about 60 meters

An ancient crocodilian that has mutated when he was infected by an unknown alien parasite. Incredibly, he managed to turn the cards and take control of the creature. From that day onward, his main goal was simply to LIVE, and since then many parasites have tried to take life from him, only to become victims for his personal use.

Powers:

Flexibility- Through his mutation and fusion with the alien parasites, Rukrash's skeleton has become much lighter than norm, acquiring a somehow elastic consistence. He can bend and move like no other crocodile can do. Also, his skin changed, becoming far less armored and smoother, almost like a fish'd or a worm's hide. This makes him overall a lighterweight than most crocodilian kaiju, but he is far more agile than most of them and can easily make up for his feeble strenght;

Light Armor- His mutation has deprived the crocodilian of most of his armor, and he retains just few plaques on his back that can barely count as protection;

Lethal Jaws- Even though he is a crocodilian, Rukrash's jaws are quite a unique case among the family. His elastic bones allow for an enourmous extention of the jaws, with the mouth being able to align both skull and jaw vertically. The mouth is also full of razor-sharp, diamond-hard fangs, that both penetrate and cut flesh as easily as a sword with paper. Also, his mutation granted Rukrash a pair of fleshy 'cheeks', filled with the same fangs that adorn his whole oral cavity.

Parasitic Heads- Out of Rukrash's back sprout two long heads, both looking like they just erupted out of him. These are the remains of the two parasitic Lampreys that first attached to his body, and were then assimilated by what they thought an easy victim. Now nearly completely mindless, they live only with the goal to ensure the survival of their host, as such they attack anything on sight, unles Ruk's will stops them. They can act as both whips and tentacles, and can painfully latch on enemies to start draining them of life fluids.

Saw Tail- Ruk's tail is full of uber-elongated and hyper strong scales, as such, with enough force behind it he can use it to cut most enemies's hides open;

I Feel You- Rukrash's sight has seen better days. In fact, he can't distinguish colors, and can make out object's shape with difficulty. However, what he can't see, he feels. Along his sides lay rows of black spots, extending also along the Lamprey heads. These spots are actually receptors and can receive various signals from the outside world, transmitting an image to the Croc's brain. It is unclear how these sensor work, but they seem able to both detect electrical fields and discharge a brief, harmless magnetic field that allows the sensors to take in completely Ruk's surroundings. This charge can be released at will with little to no effort, giving the ancient parasite a first-class radar;

Nightmare Projectiles- If Rukrash's skills were frightening in melee, in long-range combat he's the nightmare of all that is acquatic or amphibian. Out of his Lamprey heads, Ruk can, at will, releast a colony of one of the most feared fishes in history: Candirù Catfish. These are actually hybrids between the common Candirù and the Candirù Asu, which means they are fired, head straight for prey, then use their sharp teeth to burrow into the first bit of flesh they come across to, WHATEVER may it be. How Ruk can use these fishes, it is whidely unknown, even if it is belived he has absorbed them when they tried to live off of him. These fishes, also, seem to retain some of the Candirù's nastiest habits...;

Personality:
Rukrash is a loner, wanting nothing but to stay by himself. However, the most dangerous thing about his is his will to survive: the sheer power of his will made him overwhelm and take control of the alien parasite that first tried to claim him, and that allowed his to gain the ability of life-absorption: he will, to endure, consume any living being he sees. That is, however, when his blood supply runs short. When full, he is a threat only to those wandering in his swampy lair;
