'Titans' Season 2: Superboy and Starfire are far too powerful to be on the same team together for long
While it's definitely fun for the fans to see these characters fighting side by side, the problem is that there really aren't any villains on the show who are powerful enough to give them a real challenge.
Though quite a few of the Titans don't have powers as such, the ones that do are spectacularly overpowered. Rachel Roth / Raven (Teagan Croft), Gar Logan / Beast Boy (Ryan Potter), and Kory Anders / Starfire (Anna Diop) are all quite OP in their own way and, as if having a demon child, a shapeshifter, and an alien who's basically a living sun wasn't enough, the team now has another powerhouse added to their ranks.
With Conner Kent / Superboy (Joshua Orpin) having been brought to the Titans Tower, the team now have the world's deadliest infant in their corner and there are not too many villains who can stand up to that kind of firepower. Individually, both Conner and Kory have the power to take down entire armies on their own but put together, they're truly an unstoppable force. As a clone of Superman, Conner draws his powers from the sun and that means that so long as he's with Kory, who has the power to store and release massive amounts of solar energy, Superboy is practically invincible.
We saw an example of this in 'Titans' Season 2's seventh episode where Kory managed to cure Conner of Kryptonite poisoning by blasting his body with the power of the sun. As any Superman fan (and even most laypeople) would know, Kryptonite is the one thing that can stop people like the Man of Steel and by putting Conner on the same team as Kory, the show has effectively removed that weakness altogether.
Right now, Conner is still a child, his mind barely more developed than an infant's, so he's not yet at his full potential. However, Kory is the most level-headed of the Titans and she could become a guiding influence on Conner, shaping him into a true hero.
While it's definitely fun for the fans to see these OP characters fighting side by side, the problem is that there really aren't any villains on the show who are powerful enough to give them a real challenge. Even Deathstroke (Esai Morales), whose very name strikes fear into the hearts of veteran heroes like Dick Grayson (Brenton Thwaites) and Donna Troy (Conor Leslie), would be completely out of his depth if faced with the combined might of Starfire and Superboy, which is why it's unlikely that the two heroes will remain together on the show for more than a season.
It's very likely that either one of the characters will take off on their own by the end of Season 2, possibly to star in their own spin-off show, or perhaps they may even get killed, though we're not quite sure what threat would be able to kill either of these powerhouses. If the writers do intend to keep Conner and Kory around for the foreseeable future, they really need to bring in more powerful villains who can actually give them a challenge because otherwise, this story is going to get very stale, very quickly.
'Titans' Season 2 Episode 9 'Atonement' will arrive on DC Universe November 1.
