User blog comment:Spirits of nature/Possible Legend for the season 3/@comment-3221148-20170223193457

In the comics, Legends of Tomorrow contained Firestorm, Metal Men, Metamorpho, Sugar and Spike.

I think Metamorpho is certainly a good candidate.

Rip Hunter also led these teams in the comics: http://dc.wikia.com/wiki/Forgotten_Heroes http://dc.wikia.com/wiki/Time_Masters http://dc.wikia.com/wiki/Linear_Men

(we've got the Waverider, Time Masters and Eve Baxter from those)
