Super Mario Bros

Ah the world of turtles, shrooms, and plumbers. A colorful land with power ups a plenty. Well, you'll be giving the girls of this universe a power up they won't forget.

As always there is Princess Peach a gentle ruler and lovely woman..., only to get kidnapped most the time. Still, she was the head of the kingdom, and her powers usually had a negative effect on Bower's plans so it was a good idea to remove her from the board, so why not follow the same path as those set before you? Her blonde hair and pink color choice would make for an excellent color combo for a uniform. The Toads, Mario and of course Bower might take issue, but you'd have a whole kingdom of resources and power ups to use.

Or you could go for Princess Daisy, a far more tomboyish princess who loves sports and playing hard. She'd be more likely to accept and thrive under your banner, and you do like spunky girls anyway. Just some issues. Daisy would be easy to sneak away, because her Kingdom isn't really ruled by her much these days, it's far more self sufficient. Her Desert Kingdom is also well a desert, and the resources gained would be sparse. And Daisy has shown skills and abilities but magical wise she seems weaker than Peach. A choice of 'Easier recruitment' vs 'Resources gained' between the two.

Rosalina is another choice, giving you access to the galaxy side of the Mario universe along with a new base. Though you wonder how her little star helpers will react to a new 'momma'. And her powers are somewhat unknown compared to the other two. Along with her far more gentle nature(Peach could be a right bitch in Mario Party and Brawls), you're unsure as to what sort of reaction she would have.

Or you could go the way of the 'meme'. You feel in love or at least like the idea of Bowsette. A powerful, strong willed, muscular woman made you weak in the knees, even if it was just Humanized Bower. However she was never actually Canon, though you're confident you could either find a world where she did exist, or just convert a version of Bowers to her. All the resources of his..., her kingdom would be yours, and an army ready to convert.

There are still others you could go for. King Boo perhaps? Go for the Brothers themselves? Some of their allies?
