The Pirate of Legend

(Ties into Arrow/Amazon story and Deku in central City as well).

Ray palmer used to be known as Captain Marvellous a brilliant, smart space pirate. After his team were killed by Zangyack, he wanted revenge and went after them, but wasn't able to defeat them.

So he decides to go to Earth (see his team where looking for the Greatest Treasure, but the Zangyack where on their tail), but Zangyack catch him and shoot down the Gokai Galleon and he has to survive on his own. He decides to create the identity of Ray Palmer and becomes CEO of Palmer technologies. After his apparent death, he realises no one truly cared and goes back to being a pirate and left Star City after fixing his ship, but decided to use it as it's over option, a normal Pirate ship instead of an Airship.

He doesn't care about Earth, but when RIP not only gives him a chance to steal literally anything he wanted, but also defeat Zangyack so he can make his wish to bring back his team after finding the Greatest Treasure in the Universe.

Whilst doing that he also has to not fall for most of his crew (minus rip and Stein. Jax is aged up and Mick is the same age as Leonard)) as they fall for him. He also has to remember that he's no hero and is just doing this for his old crew.
