""In the hospital, and due to the flowers weakening him and his lack of suppressing drugs and willpower, he succumbs to the infection and transforms into a monster, becoming one of the most major antagonists in the game. Kenny becomes the most frequently fought boss throughout the game. He seems to have keep most of his intelligence, though he is rendered completely insane.

The infection has the better of his will and turns him into a grotesque being endowed with intelligence and the ability to express himself, but totally devoid of humanity. In this guise, Kenny, intoxicated with his new force, reveals a dark and cruel side amplified by the Mortifilia feeding his insanity with the agresiveness that the mutation provoces and frees a macabre perversion to all those who were once his friends.

His upper limbs grows to allow him to rest directly on these rather than on the legs, on his chest it opens a hole, while the rest of the body, though evidently changed, stays with a human appearance, particularly the facial features. His strength and his agility are increased dramatically allowing him to propulse on the walls, run and jump more quickly by relying on his huge arms. In this state, Kenny can generate clouds of dark spores that becomes solid to throw at enemies with his hands causing average damage, but due to the "solidness" they can't infect others. At close range, he can attack with his upper limbs.

He can survive direct sunlight, as the final battle with him is set at dawn, but the light weakens him. This can be proved:

In his 2nd battle he was crush by a giant metal thing (This one could weight equal or a bit less than the reflectors of the stadium) and fall a great height with this thing on him. He was able to survive that. But in the last battle, being exposed to sunlight, he is crushed by another heavy metal, but this time, dies.

It is important to note that the weight of the reflectors was distributed in 4 part, Kenny would be one and the other 3 would be the groud, so the weight applied on him, would be theorically damaging, but less than the power generated by the crush of the metal thing in the Dam.

He is capable of mutate futher than his 1st showed form, as seen when he mutates after his 3rd and final battle. There is no explanation of the futher mutation, but it can be theoried 2 options:

He mutates after a great amount of damaged produce, regenarting the missing cells and creating new ones. This can be explained by the fact that he was crush in his back where he had a little thing, like a tail, coming out from his "hump", and after the mutation a "claw-ending tentacle" thing was sticking out of Kenny's hump.
Or, his 2nd form was the meant to be, as the "tentacle upper limb" taked time to develop.""
