Don't forget the future. Kamandi...The Leg--No! I mustn't allow myself to hope for that one....
Yeah, the Legion is one I'm hoping against hope for. I saw a comment from one big wig that said they weren't going to be introducing a shit ton of DC characters on these shows....but I also recall Geoff Johns saying that he wanted to do as many live action versions of as many DC characters as he could.
My top picks of characters I would love to see in the Arrowverse would be:
1. Starman. Don't care if it's a modern day Jack Knight, or a cool retro costumed Ted Knight.
2. The Legion Of Super Heroes.
3. Adam Strange. Time to see DC's cosmic side.
4. Doctor Fate. Also time to see DC's magic side.
5. The New Gods. Though I have a feeling that won't happen because they'll want to use Darkseid in a JLA or Superman movie at some point.
6. The JSA and not in a WW2 setting as the older I get, the more I hate that they've been associated with it to the extent they have.
7. The Golden Age Green Lantern because he's my favorite
Also, I'm really disappointed in how Jay's been used this season. I would've preferred a two part "Flash Of Two Worlds" where Jay was powered up, and he and Barry went up against a cool villain and then Jay went home. That we got an episode using that classic title, but with a depowered Jay was a huuuuuge let down.. We were also told that Jay would be like a big brother to Barry, and this implied that he had been the Flash for long enough to have the kind of experience he could pass on. But that only lasted for one episode before we find out he's only been The Flash for maybe a year longer than Barry. Then Wells pretty much says that Barry is faster and a better Flash than Jay was and the show doesn't do anything to dispel that.
So the whole "Jay as big brother" thing has been a bust and now Jay's reduced to the odd "hey, remember me?" type cameo's where Jay just shows up for a brief moment to remind us all that he's still around. I'm really hoping that they power him up for the finale, and that it does justice to the original Flash. I'd also like to see an annual team up episode between the two in the tradition of the old JLA \ JSA team ups.
