Ghostdiva got there first, she wins.
Unfortunately, there's no prize.
Yeah, I couldn't help myself. I guess it's the last name they gave him.
Of course, I had to put my own spin on the matter:
IDW Egon is a caricature of Harold Ramis, and IDW Roger is the EGB Egon character design. Well, since Ectozone Egon is basically RGB Egon with whitening hair, Ectozone Roger picks up more of a Ramis look--though since I didn't use EGB Egon, Ectozone Roger keeps some of the haircut. I did take the ironic touch of giving him basically the same aging cue as Egon--the whitening of the hair in the back.
Does this mean I'm going to have a GBOT version of Roger appear? Not necessarily. I'd like to see him developed a little more in IDW's narrative before making a final decision.
And even if he does
show up in Ectozone fan fic, he certainly won't have the same role as he has in IDW's story: Janine Melnitz Spengler is a very happily married woman in our universe, thank you. I may give him a love interest named "Janine Burnham" though...
No, more likely, if a GBOT Roger appears, it'll probably be through having the same last name as this guy
(thus the slightly reddish tint to his hair, matching that guy).
