Steven Universe - starring pearl as Dib and amethyst as Gaz

Peridot is essentially a magnificent fusion of Zim and Jack Spicer. We just need the robonoids to be minions that attack the Gems, and we'll be set!

And if Pearl's Dib and Amethyst is Gaz, that must mean Garnet's Membrane. "Not now, Pearl! I'm making…. Fusion!!"

Oh, and Lapis can be Tak! Yeah!
