New Code-Names for Kon El and Tim Drake

[lemonpeace]

Rook was an old Warren comic magazine character who has been brought back more recently. (By Dark Horse I think?)

Your right there is/was (iunno if it's still going) a Dark Horse character title called The Rook but, well, Rook (chess piece names in general) aren't super uncommon so I'm not surprised. However, that character's name is THE Rook, I would advocate just for Rook and lean more on a rook as a bird aesthetically as opposed to the easy chess route. I would also make his primary color green to make him more visually distinct and I want each bat character to have a distinct color (Nightwing blue, Red Hood, Signal yellow, Orphan black/gold, etc.).

He is too old for Kid etc.

I would go with:

-Flamebird
-Steel Eagle
-Steel Titan
-Helios
-Valor (Mon-El didnt use this name anymore or?)
-Sentinel (was used by Alan Scott once)
-Steel Hammer
-Saviour
-Beast Slayer
-Doom Slayer
-Steel Phoenix

Your never too old for Kid so long as your youthful, plus It's more of an editorial name, he'd mainly just be Conner (or occasionally Kon-El). Some of the names you suggested sound pretty cool but (and mind you I'm not super in-depth with Superboy) my interpretation of Conner is all about maturity and growing out of your flashy teeny-bopper phase into a responsible adult. So in my mind what better way to demonstrate that than to have him stand tall and just be who he is. His wife and child are from a different dimension and he doesn't have an earth civilian life due to being ejected from the earth for so long. I mean, what better way to distinguish him from Superman than to have him take Clarks open face mentality as Superman and evolve it to full transparency?
