Invader KET: Ket is an Irken Female. She is known as an exiled defective.
Invader KET is a known wanted fugitive to both the Irken Government and the Earth Government. She, along with Thorn, Invader Mel, and Invader Jez, are believed to be dead by the Tallests. But, here's the thing: They never die.
Ket has the ability to transform into a dragon. Her D.N.A. sequence changes whenever she does that.
Weapons:
Like Thorn, KET enjoys using knives.
At the ends of Ket's antannae are two venomous barbs. If you get stuck with one, sooner or later you shall die. (Oh no!) However, Ket has the ability to dispense her venom at will. So does Thorn.
