Brockium

Brockium is a chemical substance that forces dragons to shapeshift into their dragon form unwillingly. It is featured in the television show American Dragon: Jake Long. It was developed by Sigmund Brockin his attempt to expose magical creatures to the world.

History
Sigmond Brock, a researcher of the Magical World, entered in a deal with a unknown party. With this parties resources, Sigmund created this substance but he didn't have a dragon to test it. After Jake caused Rotwood to be fired, Sigmund became Fillmore Middle School new principal.

He planted magical bugs on the basement, thinking that it would draw the dragon to fight against them. His plan worked as Jake, Trixie and Spud went to the basement to fight them. Brock then brought Jake to his office where he revealed his plan on expose magical creatures.

He later trapped them in a jail and pushed them to the auditorium where he planed to use the brockium. However Rotwood lied to him telling that Spud was the dragon. Sigmund used the vial on Spud who, obviously didn't shapeshift, making him look like a crazy man. A drop of the vial, however, remained and Rotwood used it to shapeshift Jake's hand, thus proving the chemical worked..
