8) Elongated Man
DC’s answer to Mr. Fantastic, Elongated Man is a prime example of the sort of hero the Arrowverse can highlight, seeing as the big hitters are off the table thanks to the movies. He’s not a bargain bin hero, however, as he’s actually a pretty big deal, being a frequent member of the Justice League. As such, it would be great to see the guy turn up in The Flash season three.
Elongated Man’s alter ego, Ralph Dibny, was mentioned in season one as someone who died in the particle accelerator explosion. But what does that matter? They could just have him presumed dead before he makes his return as Elongated Man in season three.
[zergpaid]On the other hand, there might not be a long-term role for the character on the show, so maybe he could just be introduced on The Flash only to hop over to Legends of Tomorrow to join the Waverider crew for that show’s second season?
Either way, we’d love to see Elongated Man join the Arrowverse, as he’d make a great addition to any of The CW’s superhero series.
