The main incentive for Bubble Power She-Ra is the new 2.0 female body. Essentially this She-Ra is specifically designed to sit on Swift Wind as the Original MOTUC She-Ra simply can't. Now if you want a Filmation-esque She-Ra that rides Swift Wind you need to take the head and cape of the first She-Ra and pop into the BP body. Also Bubble Power She-Ra is a vintage toy accurate repesentation of the Original Princess of Power doll, complete vintage tiara/mask thingy, toy accurate sword, removable armoured skirt dealie and little bubble blower weapon whatsie. Personally I'm counting this as "Battle Armour" She-Ra as I've got BA He-Man riding Battle Cat and BA Skelly riding Panthor, so it just makes sense for the display. Hope that helps!
