User blog comment:Eobard95/Legion of Doom as villains for next crossover?/@comment-27167599-20170323004019

I think Damien Darhk and Eobard Thawne will probably find a way to exist in the legion even after there Dead in the timeline through time remnants or something. And I think  Damien Darhk Will get his magic back somehow. Apart from them the only villains I'd add to the list are Grodd and Lisa Snart.

I think It would be interesting having Killer Frost and the Reverse Flash on the same team. If Eobard Thawne knew what would happen to Caitlin since  she started working at Star labs the shock of that revelation  would push her further to the dark Side. I'd also love to see more Firestorm and Killer Frost. As for your idea about Ronnie I think  it would be easy for the legends to bring back Ronnie since his body was thrown through A portal like the one the wave rider travels through. But I've been hoping for Ronnie’s return for years now and I don't think it's going to happen.
