Final Countdown is an alien from Tech 10: Star Spirit.
Final Countdown's abilities include:
Final Countdown is a gold and purple humanoid alien with a somewhat armored, robotic appearance. Tubes and nozzles are set in his shoulders, legs, torso, and head, and he has two metal orbs at the end of each fist. There is a gold star between each set of metal orbs, and he wears the symbol of an unknown Omnitrix on his chest. He has no mouth, and three thin rings are vertically attached to the top of his head.
Final Countdown's temporal and spatial abilities aren't nearly as powerful as TyMR's or SPAse's, respectively.
In Not Yours, it is stated he can only stop time for an upper limit of five seconds.
Planet and Species Information
Final Countdown is a genetically modified Kronis from the Temporal Nebula.
Natural members of the species demonstrate an extreme version of sexual dimorphism, with the males and female having very different appearances and abilities. Final Countdown appears to be a merging of this dimorphism, granting him unique abilities.
Only a few Kronis ever came into being, each one eventually leaving the nebula for other parts of the galaxy. Seeing a Kronis is extremely rare, and only a few people in existence have ever laid eyes on one.
Compared to the other major Chronokinetic alien in Star Spirit, Clockwork, Final Countdown's chronokinetic abilities are rather poor, only being able to control time in a rather limited fashion. He makes up for this with his other abilities, which make him more suitable for direct combat.
