My 10 would be as follow.
1.Vixen=created in 1981 Mari deserve her own series
2.Nubia=Nubia was created in 1973 and has recently been seen in the page's of Wonder Woman
3.Bumblebee=Karen created in 1976.1 of my Fav DC heroes married to Mal Duncan
4.Black Canary=Dinah created in 1947 DC ICON long overdue for another Ongoing.
5.Troia=My poor Donna.DC has done you so much misjustice.u deserve a Ongoing.TV Show.Movie.Animated Series 4 everything u been thru.
6.Herald=Mal Duncan DC's 1st African American Heroe created 1970 should have an Ongoing w his sonic based powers in tact n maybe Lead a Titans team w his Wife Bumblebee
7.Red Star=created 1968 every since NTT#18 I've been a fan n would love to see him on a JLI Team.
8.Captain Comet=created in 1951 i'm a fan of Telepaths/Telekinetics n besides Martain Manhunter. Adam definitely needs more spotlight time
9.Geo Force=Brion created in 1981 was excited when he going to be a member of the JLA.didn't last long thou.but would love to see more of him.
10.Black Lightning=created in 1977 besides the Outsiders.Jefferson should also have his own Ongoing again I don't think that DC has ANY African Americans Solo's at the current time n needs to put a change to that.
