Almost a year later, and it looks like Khris has grown some since appearing last year when he first showed up. But not quite an adult yet. (He is still shorter than his adopted sister Gwen)

Sporting an updated and longer shirt. He now wears long shorts.
A size comparison for both Khris and Gwen is coming sometime later today/night (as of this posting).
I will also add in some extra info, alongside previous info, about the two in that image as well
I also want to mention that, despite him being a little bigger now, comics with him will still use his younger appearance (for a time)
