Remember Supergirl season 2 when both Kara and Mon-el when through a portal to another planet while visiting a doctor. Kara was unable to use her powers because there was no yellow sun. Luckily Alex and her DEO team came to the rescue. Alex released a yellow sun grenade which enabled Kara to use her superpowers.
