Bullfrogs

"There is no antidote for our ire!"- Battle cry of the Bullfrogs

The Bullfrogs are a Salamanders successor chapter created during the 21st "Cursed" Founding. They were created to support the forces of the Imperium in the Celestionic Sector. However, they were cursed with a mutation thanks to their magos creators. This mutation is in the Bletchers Gland, which makes it secrete the toxins onto the skin of the Astartes, creating a film of acidic mucous. As a result, they have modified their armor to protect against being corroded by the mucous and their relations have deteriorated with the locals thanks to the mucous slowly eating away at their skin, creating a smell of death and decay.

They are considered the leading experts in chemicals within the Celestionic Sector thanks to their mutation. They suffer from shortages of neophytes thanks to the mutations in their gene-seed killing most. They are fleet based, as they don't want their acid to infect others in an outbreak.

Founding
As with many chapters of their founding, they are very unfortunate. They are cursed with a mutation of their Bletchers Gland, which secretes a acidic mucous onto their skin, creating a film of acid. Their first suits of armor were quickly corroded due to the acid and they were forced to modify their armor to cope with the mutation. They seem to have avoided the 'bad luck' that many chapters of the 21st founding seem to have.

Brazili
When they were sent to the Celestionic Sector, they arrived with their ships in tatters. The Astartes corroded and disintegrated their ships with every touch. As such, they were forced down on a planet called Brazili, a planet completely covered by a dense rain-forest and home to all forms of deadly insects, animals, and a small human population.

The humans from this planet are considered to be the toughest in the sector for being able to survive the horrid conditions they endure. They at once saw the Astartes and believed them to be the mythical saviors from their hell on that planet. They at once went to help them as much as they could, giving them food, water and helping to modify their armor, weapons, vehicles, and ships to be resistant to their acidic touch. Soon after they were repaired, the soon-to-be Bullfrogs decided to recruit from this planet. The locals believed that they were taking them to be free from their hellish existence. But they were just condemning them to their own hell.

Naming
The chapter was told tales of the mighty Giant Bullfrogs that roam Brazili. Carnivorous beasts, they spit their toxic acid to disable their prey. Touching them is fatal, as the acid coats their body, killing anything that touches it. The chapter saw themselves in that animal and named themselves the Bullfrogs. They painted themselves the colors of the Giant Bullfrog to commemorate the link with Brazili.
