Amazo from young justice; •Black Canary. •Captain Atom. •Flash. •Green Lantern. •Wonder Woman. •Martian Manhunter (no mind control, mind rape or any other powers using his mind) •Red Tornado. •Superman. They are the tv show version of this charectores not the comic version. Nova is not from the tv show. Amazo can't copy nova's powers. To death. Nova has the entire nova force. Takes place in empty earth.
@dondave: Not sure, I don't know much about Amazo
His ability is to copy others by looking at them (that might just be from the Justice League cartoon, however). In all media, he has the capabilities of most, if not all, of the main Justice League members within him. Sometime he can use all his powers at once, other times he can only use one person's abilities at once. Young Justice is a case of the latter.
I see Amazo winning.
@MorganFreeman: Whats to stop Nova opening a black hole in his head?
I don't think Amazo would allow it to happen easily what with his great speed with the various quicksters in his skillset. Though if it did happen, Amazo is probably done for.
The JY Amazo don´t really has any feats and most of the JLA member that apear in the show have neither so it´s very hard to determine if he is powerful enough to compete with a heavy hitter like Nova, when he has the whole Nova force and worldmind. Because of this doubts i give it to Nova.
Rider ROFLstomps Young-Justice!A.M.A.Z.O. by sheer overpower. That AMAZO is shown to be very mechanical and simulated "copied" powers with stuff like wires and servomotors. Now JL-Nano-AMAZO is a completely different beast, and maybe he couldn't flat out take on Rider's powers (as the entire force is within him), he's still unrelenting, self-regenerating machine of grey goo...
