5. Red XIII & Cait Sith (Final Fantasy VII)
A slightly unusual combination this one, but one that could potentially prove fruitful in practice. Red XIII and Cait Sith appear in Final Fantasy VII; the former is a wise, brave and powerful member of the party, while the latter is a little cat that rides atop a huge mog, and is pretty much the complete opposite of Red XII personality-wise. In the sequel movie Advent Children, the mog is nowhere to be seen and Cait Sith stations himself on Red XIII's back, an arrangement reminiscent of The Legend of Zelda: Twilight Princess. With Cait Sith operating as a guide of sorts and perhaps providing special attacks and abilities, maybe a Zelda-esque game could really work here. Starring Red XIII as a guardian of Cosmo Canyon, it could easily be set shortly after the original game, and even around the time of AC since both characters essentially make cameo appearances. Of course, all the old towns and villages could feature as the protagonists venture all over the globe to thwart the ShinRa, The Turks or some new threat.
