Atlantean are not metagene, it's magical. I think only black canary, flash (the accident probably triggered his metagene), and captain atom, and possibly icon, rocket, and black lighting have a metagene. The rest are magic, divine powers (yes, Cap Marvel's are divinely imbued), come from an object (ex. lantern ring), or are natural physical abilities in a species (hawkman, hawkwoman, manhunter, superman, etc.). And the rest of the league is just normal people (green arrow and batman).
