Usagi/Bunny Tsukino or better known as Sailor Moon has joined SSF2...as a mod, but even then she offer plenty of interesting things to offer. She can summon the other Sailor Senshi to aid her in battle and keep enemies at a distance so she can finish them off and if her damage is above 65% she can even turn into her Super Sailor Moon form. Not only that, but the mod has 10 Final Smashes, 5-5 for each form. Which can either be summoninger her allies or she herself transforming into Eternal Sailor Moon or Princess Serenity.
Put the data file into your SSF2's data folder and don't forget to make a backup.
