Hello,
DESIGN:
talking about Conner, my favorite artwork regarding Costume etc. is “A Rebel Without A Cape” which you find at Deviantart.
It is really the best picture which I have ever found, because it combines the 2 Superboy Costumes and he also looks like a 20 year old guy in it.
Its simplistic cool and much better than the designs which DC is using at the moment.
PLACE:
Conner must move out of Smallville or Metropolis and go into another city. Best would be back to Hawaii, because Hawaii gives another feeling than Metropolis and he can become the hero of this place of USA again.
POWER-SET:
Full Kryptonian Powers+TTK, but stronger than during the TT Era, because he is older now.
Combined with the intelligence of Lex Luthor.
PERSONALITY:
I also hope that DC uses the TITANS TV Series Conner as inspiration and shows Conner more as combination of Lex and Superman. In the Comics Conner is at the moment to one-dimensional and boring.
I like the Idea of him as combination of the characters which influenced him:
So he is on the one hand still the fighting, unstoppable character of the Johns TT Era, but on the other hand he is more mature, has developed an interest in technology, biology and reading and has became a more mature character who can also lead the Titans and is character who is also not afraid to clash with Batman, Superman etc.
So he is more like the Nightwing of the Superman Family-a role-model for the younger generations and I also like that he develops a father-son relationship with Lex trough their mutual interests for technology/biology etc.
I also really liked the way how DC portrayed Bart during the TT Era-showing that his favorite writer is Mark Twain and he can relate to his works etc.s
FAMILY:
I like that he develops a father-son relationship with Lex, gets back together with Cassie and become engaged to her and considers Bart,Cassie and Tim as his family.
