Ruby Rose & Yang Xiao Long vs Sans & Papyrus - Human siblings that hunt monsters vs Monster siblings that hunt humans, also Yang and Sans both make puns a lot

Ben 10 vs Beast Boy - Transforming superheroes associated with the color green (also arguable that they once had really good shows that went down the shitter with subsequent series/reboots)
