Profile, Abilities and Weaknesses description from The Transformers G1 series by Marvel Comics.

Profile: This merciless, polluting parasite is so foul that even his fellow Seacons do their best to avoid him. A peculiarity of his circulatory system permits small amounts of lubricant and other chemicals to bubble to his surface through joints and welds.
making Skalor the malodorous menace that he is. As a result, he leaves-a disgusting trail of grease and toxic chemicals wherever he goes. Although often advised that this condition can be easily corrected with a few minor adjustments, (particularly by those who have to work with him), Skalor chooses to continue just the way he is. The smell doesn't bother him. He feels that if the smell bothers others, that's their problem, not his. But this argument obscures the real reason for Skalor's foul scent: He just doesn't care about personal hygiene. And the fact that his odor occasionally keeps his enemies at bay is a bonus that he uses to defend his slovenly lifestyle. 

Abilities: In creature mode, Skalor operates equally well on land or at sea. He can clamp his vacuum-suction mouth onto most ships and, by piercing their hulls with his diamond-tipped teeth, suck the fuel from them. A snap of his turbo-powered jaws can cut through any substance. His maximum swimming speed is 35 knots. His underwater range is 4,000 miles. His heavy armor allows him to function at any depth. In creature and robot modes he wields two crustation rifles, which encase and immobilize anything they hit with a stream of hard, sticky scales. One rifle shoots the scales, the other shoots a viscous adhesive that glues the scales to their target. In weapons mode, Skalor transforms into a twin-barrelled corrosive slime-shooter. He combines with his fellow Seacons to form the super-robot Piranacon.

Weaknesses: As a result of his leakage problems and generally poor self maintenance. Skalor is prone to minor but frequent breakdowns. All are the result of low internal fluid levels. He sometimes overheats, suffers from locked joints and strips his own gears, for example. Occasionally he becomes immobilized at the bottom of a deep ocean and must be fished out by his fellow Seacons.
