Toxo-Vipers are Cobra characters from the A Real American Hero series.

Being a Toxo-Viper is not what a Cobra aspires to be. In fact, it's a position meted out as punishment for the most discipline-challenged troopers. Working with hazardous substances is not an assignment anybody wants. The Toxo-Vipers' objective is to enter the battlefield and create a foul environment to cause the enemy to retreat or put them in a severe disadvantage. While the toxic weapons they wield is already a major turn off, it is their equipment that makes them most wary. It is the source for their disparaging nickname, the "Leaky Suit Brigade". While the suit is moderately airtight and resistant to most solvents, they are made cheap and only for practical purposes. Whoever designed the suits did not have protection as the highest priority in mind.
