Flash is confirmed to appear in another episode and I believe Green Lantern's episode is coming up soon.
No idea if we'll see them together this season though...
That would be a shame considering how much they've featured Firestorma and Plastic Man. You can't you use the the show as an excuse considering that Batman, Superman, and Wonder Woman are in Justice League and have their own movies.
They aren't ashamed of Hal. It is the "racist" John Stewart cries that are making them hesitant. They can use them both... actual armies do have many soldiers.
I get it... but man I HATE Plastic Man!
Firestorm is a clear favorite (he's the most consistent guest hero) but the creators were open about the Trinity being the only real anchors as far as the cast is concerned.
Ah, I love Plas. His episodes have been really fun .I get it... but man I HATE Plastic Man!
Parental care is way exhausting. Gained insight into what my parents went through when I was a baby. Not fun, but what ya gonna do? (Read comics, obviously.)
