4. Oliver Queen / Green Arrow
One man who seemed destined to give Sara Lance a run for her money in the “I’ve died twice” department in Crisis On Infinite Earths was none other than the Green Arrow himself.
Oliver Queen was so committed to saving the multiverse during the Arrowverse’s long-teased Crisis event that he was willing to lay down his life twice, as he delivered two heart-wrenching death sequences that left us crying our eyes out at the start of the crossover and the end of it.
With Supergirl’s Earth-38 about the succumb to the wave of anti-matter, the Emerald Archer hung back until the last moment (after The Monitor had sent all the other heroes to Earth-1 for safety) so that he could save as many lives as possible. He did that, having an emotional but powerful last stand against an unrelenting army of Shadow Demons.
He later returned when the multiverse was gone, now appearing as the supernaturally-charged being known as The Spectre, and did battle with the Anti-Monitor before ultimately rebirthing the multiverse before bidding an emotional farewell to Barry Allen and Sara Lance.
It was a heartbreaking but triumphant way for the man who started it all to bow out, and it ensured that The CW’s highly-successful shared universe of superheroes had now earned the name “Arrowverse”. The ultimate tribute to its founding father.
