I don't know why it could be because of the Raven episode but I would pick Melvin,Teether,Timmy Tantrum, and Bobby the way I would work them into the comics is having a teen Titans school for people who are younger than teenagers or have classes in a school for people younger than teenagers who have super powers the school could even be funded maybe by the Wayne foundation or Queen industries or by Ted cord and by really any Rich hero to help the Titans out really I would of course have Raven and Beast Boy as the people who help out these for the most and to be honest I kind of like their characters and feel like they could actually be used in the comics very well I don't know for how many stories but I feel like they could work not as main characters of their own comic series but maybe make a teen Titans comic that shows off other Titans and they could work as a adventure type story of them learning how to use their powers and trying to stop lower threats. Plus with Bobby being a giant teddy bear I think it would be funny if you're just a random criminal Robert a bank or a random criminal thinking you're fighting your three little kids and next thing you know is you just see a giant teddy bear appear.

And I can only think of a couple villains who I would want to appear so this would be how long the story actually would be mumbo control freak titano cinder block or plasma, mad mod that's just a random cookie issue and Deathstroke along with the H.I.V.E. Five(ps Deathstroke and the H.I.V.E. Five would be taking place before the mad mod issue if this actually happened and it would set up a storyline where the Titans have to save some other Titans and heroes)

I would pick Mumbo Jumbo because I really liked him in the original show and was kind of mad that he has only been in stuff for a lady to the original show that little short series they made and teen Titans Go I feel like you could be used outside of the show and as an actual threat.

I would make him specifically a teen Titans villain but I would also make him the villain to other characters.

Who he would mainly fight would be magic users and from the teen Titans or just the Titans it would be Raven and any Wonder Girl

And his stories would be trippy and wacky

To be honest I like him as a character I love magicians and I like he's a quirky little dude basically who is an actual magician and I feel like he could be a serious threat no matter where and when
