Random Kell Concept
I had a thought while working on things (promise I'll be back soon! At least with sketches). What if Kell-El didn't like physical contact? Gotta say a lot of it would be very foreign to him being raised as a war tool. So trying to be physical isn't something that comes naturally to him. But talking (arguing, or speaking loudly) and being closer in proximity is natural because that's how he figures things out.
Kell-El, aka Superman X, and a young Superman from the second season of the Legion of Super-Heroes animated series (2006-2008).
Due to legal wrangling at the time over the ownership of Superboy (don't ask, it's too complicated for me to properly explain), the character was removed from DC Comics. Conner Kent/Kon-El, the clone of Superman who was the then-current Superboy, was killed off. Afterwards, other characters could only refer to him as Conner, never as Superboy. Heck, even DVDs of the live-action Superboy television series were pulled off the market.
Anyhoo, even though most other guys in the Legion had a name that ended in -boy or -lad, there could be no Superboy. Just young Superman. And Superman X, who was a clone just like Conner Kent, and even wore a costume very similar to Conner's.
But they were NOT Superboys.
