Superarrow

Superarrow is the het ship between Oliver Queen and Kara Zor-El from the Arrow and Supergirl series.

Canon
Oliver and Kara are introduced by Barry in 2016, when Barry recruits Kara to help fight the dominators. Oliver is overwhelmed by the thought of aliens, after having to adjust to meta-humans and lashes out by closing off Kara's involvement in the mission where he's concerned. Though Barry tries to quell Kara's hurt and frustration over Oliver's behaviour, it creates friction until Oliver realises that he's in the wrong. Kara saves Oliver's life and they fight side by side. Oliver profusely apologises and they make amends, becoming good friends.

Their alliance continues in 2017 when facing off against the Nazis from Earth-X. Oliver and Kara are surprised to learn that their Earth-X Nazi counterparts are married.
