I’ve had this idea for a few years now, one involving Ben 10 and related characters as part of the DC Comics Universe. It never seemed like a stretch to me to have him suddenly appear or to introduce him into the fold as it were. Ben 10 is a Cartoon Network property, Cartoon Network being a Warner Brothers property just as DC Comics is. Meshing the two together hardly seems difficult.
Ben is, what seems to me, a perfect combination of some of my favorite DC Comics heroes.
He has the body changing / swapping of Captain Marvel (Shazam), the Alien tech of Jaime Reyes’ Blue Beetle (before it was retconned as being magical once again), bentonite potential to be just as strong,smart, or fast as any number of heroes, and the youth and rambunctious attitude of any one of the members of the Teen Titans.
Introducing Ben into the DCCU also allows for two very cool things; One, it allows for the unique alien species featured in the original series and all following spinoffs to be introduced into the DCCU, and Two, it opens the door for Ben to access new aliens that exist within the comics. Just a few examples being Bolovaxians(Killowag), Starro, the Reach(Blue Beetle), Tamaranias(Starfire), or KRYPTONIAN.
These are only the bonuses revolving around Ben alone. Introducing Gwen and her magic gives opportunity for many crossovers with The DC Dark characters and more in depth look into Gwens powers.
Grandpa Max and the Plumbers being this super secret organization that knows everything but nobody knows of opens doors for interesting storylines in the future. How does Batman of all people not know of the Plumbers? Is this another Court of Owls situation? Only time and investigation would tell.
The thought, to me, of Ben, Gwen, or even both joining the Teen Titans roster at some point or heck being apart of an entirely new super team is extremely exciting to me!
Not to mention all the villains and side characters to pepper into the comics like Vilgax, Charmcaster, Kevin, or Dr Animo
At the time of writing this, I am not aware of any plans between DC/Cartoon Network/ WB to collaborate with one another on any project like this but I would be shocked if it hadn’t been suggested before in some capacity.
I’ll probably post some art I drew for this idea sometime soon
