The Legend of Zelda: Hyrule Warriors

[TomGuycott]

Point taken, but it would be a neat idea of some of the baddies are unlockable playable characters.

This is why I liked the DW Gundam series. Everything down to the simple machines like Ball and Zakus were playable. The main exceptions were giant mechs, which tended to only be bosses, or to be summons.
