Snorflag of Lavaton, Kutterwood of Ungle, Glayciar of Eyce, Shatter of Krystal, Warter of Layquid, Lology of Fless, Gass of Vaypoor, Durst of Zand and Shift of Tyme have been recaptured, however one more alien criminal is still on the loose.

One more alien and Luke can come home. Once more alien and Mach can go home. One more alien and the Alien Hunters no longer have to protect their home.

Eyon of Metron - the Tyrant of the Metronite people, the Emperor of the Andromeda galaxy and the Warlord of the Pegasus galaxy - is still on the run. He has not been idle with his time on Earth, he's been preparing, waiting for something that's on its way to our planet...

...and it isn't friendly.
