I see what you mean. Maybe this issue can be worked around? I remember being in another Superhero RP that wasn't supposed to be related to Marvel or DC in any way, yet I still went in and used a symbiote character. Other than references to other superheroes from Marvel, there wasn't anything else besides the symbiote. Everything from then on went rather smoothly.

I won't use the Red Lantern if you don't want though. I have another character that I made for another RP meant to resemble a Red Lantern by having the same napalm blood thing going on
