Cloak and Dagger and Nightwing

I'm trying to remember if Cloak & Dagger have made any appearances on Marvel's various animated shows.  The 90's Spider-Man series had lots of guest stars, but I don't think these two ever made the cut, unless it was a quick cameo that I have missed.  I haven't seen all of the current Spidey series, which also is guest star-heavy,  so I don't know if they have made an appearance there.  At any rate, I hope they make the leap somewhere soon because they would be perfect for animation.
