I grew up with this comic in the early 1960's. Actually, it might have been the first comic that I ever bought. With the flood of Super-Hero comics out there, can't we have just one title made up of men and women who do not have super powers?

Id read a Sea Devils title. Hopefully DC gives them one, but I think they are too obscure. Also the post Flashpoint version of them are ecoterrorists.

I'm just wonder why they didn't link them with Aquaman more then this other group

With the upcoming writer change in the Aquaman book, it would be great if the new writer did a 7-8 issue ark with the Sea Devils as the main guest stars (like Aquaman and the Others by Johns). You can also throw in other kinda obscure silver age characters like Human Flying Fish or Fisherman and make it a great story with the latest versions of obscure characters (like Johns did with Scavenger), without having to re-use the most well known villains and supporting cast (like Black Manta or Garth).

IMO DC should embrace the more exotic and obscure elements of their continuity with their Rebirth and make them work in the current timeline (like Gail SImone with Catman and everything Johns does), but not alienate them from their original concept (like they did with Lobo for example).
