Yep from the new Teen Titan Go! series. This show's been getting a lot of hate, but as a man who goes to the movie theatres for comedies, i've been enjoying it quite nicely. I'm hoping there have been others as well, because the Teen titans are getting a few boost from the show as well as having their newly found Toon force.
Super Robin(With Both Trigon's and Raven's extra powers)
Beast Boy(Ability to change into anything ala Trigon Power Boost)
Computer Cyborg(One with the Titan Tower computer system)
Raven and Starfire have their normal levels of power.
Battle takes place at Titan Tower
Essentially the challenege isn't to outright demolish the Teen Titans, but to make a fair fight for them. I've been racking my brain for days, but this is pretty powerful group(Super Robin by himself is faster than comicbook Wally West) right here, yet not more powerful than anyone to extreme like LT. You can use anyone you want(from any media), and can make teams(up to 5), but the battle has to be fair as deemed by myself(I'm a pretty lenient dude), so if anyone is willing to accept the hardest challenge in comicvine history, then begin!
