In the DC Universe, who are your 5 favorite supporting characters? They can be villains, superheroes, family members, or any character that is not the main character of their book. Only catch, supporting characters that have appeared on the printed page! No TV show versions or characters that have only appeared in a movie.
Eddie Fyers in the Connor Hawke Green Arrow series
Madame Xanadu in The Spectre
Jade in Kyle Rayner’s Green Lantern title
Martin Stein in Firestorm
Linda Park in Wally West’s Flash
Mera
Linda Park
Jay Garrick
Carol Ferris
Steve Trevor
I would mention Batfamily members, but I view a lot of their interactions more as teamups nowadays. Although I would say Alfred if anyone on my list gets bumped from the ‘supporting character’ definition.
