I was told Sticks was exclusive to the TV series. Can someone please enlighten me on her?

As to the "Bowser the main villain of the last two Mario & Luigi", they handled Dream Team well, much better than Sticker Star, because there was another main villain along with him, Antasma. And because Antasma looks like the villains of the previous three Mario & Luigi's, who all overshadowed Bowser, you're waiting for Antasma to betray Bowser, so it comes as a twist when Bowser betrays Antasma instead and leaves him to be killed by the Mario Bros. before becoming the final boss

Paper Jam is the first Mario & Luigi to not have an original main villain, but I think what they were going for there was to pair the Bowsers of the Mario & Luigi universe and the Paper Mario universe.
