Comic Book fans it's very common for someone to turn a comic book character into an animated series just look at Disney as prime examples but for every one that does get made there are a dozen or so that don't even get looked at and so i'm going to list of the comic books that I want to see turned into an animated series.
Grimm Fairy Tales
This series presents a take on classic fairy tales that is more inline with there original source material so this could make for a really exiting adult animated show heck one of the characters was so popular that she got her own Syfy show Van Helsing but just imagine if the whole Grimm universe was adapted for this series we could see Cinderella interact with Snow White and Alice and we could see Robyn Hood (that's how they spell it in this series) interact with Dorothy Gale you could do pretty much anything and it would work.
Suicide Squad
Yes I know that Harley Quinn is getting her own animated series but this one could also work as a series again the only way this could work for me is if you make it an adult series since the team is mostly made up of villains that would make the most sense and heck the recent animated movie Suicide Squad: Hell To Pay proved that the team can look good in animated form and if you wanted to tie this into the new Harley Quinn series then make this one a spin off.
Any 2000 AD Character
2000 Ad has such a great selection of characters some have already been seen in movies but none have been turned into an animated series and to me that's just wrong Judge Dredd has proven himself popular twice at the box office and you wouldn't have to stick to one genre of show Dredd could be a cop show , Slaine could a violent fantasy epic and Survival Geeks could be a Sci-Fi comedy there are so many genres you could do if these characters were adapted into an animated series.
Hellboy
Like Suicide Squad Hellboy has not only appeared in live action but also in animation and also like Suicide Squad he has never gotten an animated series despite how popular he became after the 2004 movie perhaps the reason why he's not been given his own animated series is the fact that the series does focus alot on supernatural elements but the way I see it is if Supernatural can get an anime then why can't Hellboy get his own animated series.
Vampirella
She's pretty much a vampire freaking superhero how in the hell is this not been turned into an animated series already the series pretty much writes itself and since this is a horror character you can really go all out in terms of the story and the things you can get away with all you need to do is get somebody like Adult Swim to air the show and the shows golden.
Deadpool
This was honestly one of the few things I was really excited for when it first announced and then they announced that the glover brothers were going to be behind it and I got even more excited and then they cancelled it which is a shame because Deadpool IS a cartoon character so all they had to do was put that character on the small screen that was it and yes I still believe that one day this character will get his own animated series.
Red Sonja
This character kinda got an animated film but it's really more of a motion comic but the character has never been given an animated series which is a shame because if you make the show in the vain of Xena mixed in with Game Of Thrones it could really work I really cannot be the only one who sees the potential in an animated Red Sonja series even today she's still popular this is a series that's just begging to happen.
