In an episode of Batman Beyond, an older Superman was recruiting Terry as a member of the Justice League. The episode was ok but nothing special, especially since there were so many legal problems that they had different voices for people and for instance couldn't even use Wonder Woman, and had to replace her with BARDA for god's sake.
The Justice League Unlimited episode that Batman Beyond is a part of is "Epilogue", which is one of the finest JLU episodes out there in my opinion. Without spoiling anything, I can just say that it definitely wraps up a lot of things and in a very cool manner.
That whole show was too scifi. "A human hero who got where he was through skill and dedication? Ha! What we need is a guy in super-powered combat armor!"
They should have gotten the rights to make an Iron Man series and left Batman alone, in my opinion.

But that Terrific Trio group SUCKED, they were basically the Fantastic Four. A stretchy guy and leader, a huge rocky strong guy (who was also firey) and I can't remember the 3rd one... ethey were even astronauts harmed by cosmic radiation and had a tower home!
