Bio: Finback is a sickly, crusty old sailor who often thinks about the glories of his youth. A failed naval attack mission on a chemical polluted world left him with a metal wasting disease that has been slowly and painfully corroding his robotic body ever since. Only an advanced cyber-organic shell was able to arrest the illness and keep the once mighty Finback fighting on the high seas. Although he's in constant pain, Finback still manages to spin a tall tale and enjoy a wheezing, fatalistic laugh about his condition. Combat fires his circuits up, since he no longer fears death. His goal in battle is to either make the Autobots suffer as much as he has or finally end the agony of his ongoing existence. Finback is still vigorous and skilled enough as a warrior that he always manages to survive to fight again.

Weapons & Abilities: Subject is stricken with an unknown corrosive disease as a result of contact with chemical waste of unspecified origin. The disease has not tested as contagious, but it is poorly understood. Subject's experimental Pretender shell is a mix of Transformer nano-technology and Organics. The combination resulted in mechaorganisms that spontaneously regenerate damaged circuitry, helping to preserve subject's damaged body. The scaled shell is also pressure-resistant, enabling him to dive up to 30,000 feet in liquid as dense as mercury. He wields an armor-piercing, jet-powered harpoon and a rifle that fires blasts of viscous slime capable of trapping and stunning its targets. Subject transforms into a high-speed hovercraft with an advanced scanning suite, including long range sonar. He is incredibly strong, intelligent, and highly experienced in naval tactics.

Weaknesses: Subject can't be parted from shell for more than 36 breems before his body starts to succumb to disease again. His body becomes progressively weaker and more susceptible to damage the longer he's separated from the shell.
