Supergirl Season 2: 8 Easter Eggs & References You Might've Missed In 'The Adventures Of Supergirl'
2. Mon-El
Considering that it was the big cliffhanger of season one, it is surprising that the inhabitant of the mysterious pod that crashed into National City is so small a part of this episode. All we know right now is that he is a Kryptonian-like individual. Well, actually, comic fans - and those keeping up with Supergirl casting announcements - know a lot more than that. Look away now if you don’t want potential spoilers.
It has been confirmed that the stranger (as played by Chris Wood) is Mon-El, a Daxamite with similar powers to a Kryptonian. He’s got Superman’s surname, by the way, because Kal-El considers him an honorary member of his family. The red, high-collared outfit Mon is wearing here is a nod to his fairly Superman-like outfit from the comics.
When the DEO get Mon back to HQ they find out that he’s alien by the way a needle breaks on his skin. This is the exact same way that Superman’s extra-terrestrial nature was shown in Action Comics #1, his first ever appearance.
