Reptilodon

The Reptilodons were a race of reptilian humanoids known to the Judoon. They patiently established an unassuming presence on a planet, allowing one of them to install and power up a transmat gateway to enable the forces for invasion to arrive undetected on the planet when their invasion fleet were ready. (PROSE: Rory's Adventure)

An attempted invasion of Spaceport One (a leisure and shopping complex on the outskirts of Dorfnan City), led by General Mystan was thwarted when Rory Williams activated the transmat gateway too early and informed the Judoon of their arrival, (PROSE: Rory's Adventure) while Amy Pond and Paulus kept them inside the bakery the transmat gateway was located until their arrest.
