Not good as a legacy ship. For one adaptation? Meh, sure. But it's not a thing. He's 13, she's 20-ish. Fairly sure that's illegal even on Azarath.

Potentially great in comics once Damien matures more.

I’ve probably seen more tweets about them than anyone else following the Apokolips War movie, except perhaps for the Trigon-Darkseid fight.

If Damian matures more, so does Raven. Still not half your age +7.
