Brother Voodoo and Plastic Man

The fact that these two have so little in common is what would make this an interesting team up to me.  I'm glad that Brother Voodoo has been confirmed as a character in Doctor Strange and the Multiverse of Madness, after his introduction was set up in the first film when his brother was killed. there was talk a while back about a Plastic Man movie being pitched, but I haven't heard or read anything on that front in ages.  I know that Ben Schwartz expressed interest in playing him.

The Demon Vs. Deadpool

I had always liked The Demon, but his appearances in the Alan Moore-written issues of Swamp Thing really made me a big fan.  Moore really had fun with Etrigan speaking in rhyme, and I loved reading his dialogue.  Artists Steve Bissette and John Totleben depicted him perfectly as well, they kept his design but made him appear truly demonic with sharp teeth and claws - he never looked better to me.
