So according to a report from Siliconera, Final Fantasy Explorers has a feature called Trance that lets your character transform for a limited time into a classic FF hero, in this case the article reveals Cloud Strife will be one of character you can transform into and use his Omnislash Limit Break in your battles. More characters will be available though Square-Enix will most likely reveal them in future updates along with more summons and job classes.
For those who don't know Final Fantasy Explorers is a Nintendo 3DS title that feels like a spiritual successor to Crystal Chronicles where a series of warriors battle the famous FF summons over the crystals they protect. Ifrit and Shiva have already been showcased and the Knight, Black Mage, White Mage, Monk, Ranger, and recently Dark Knight and Dragoon have been confirmed job classes the player can use. The game is meant to be a multiplayer title with the job roles working most effectively in well built teams, for instance Dark Knights take extra damage and use Soul Eater which siphons health and Black Mages are forced to stand still when casting magic leaving both classes vulnerable without a Knight or White mage to heal and tank for them.
