There's definitely a variety of familiar faces in the bunch, such as Bahamut, Ifrit and Ramuh for example, and a couple newbies too.

Read on for additional info.
A new infographic highlighting the 12 eidolons, or summon beasts that appear in SQUARE ENIX’s upcoming action role-playing adventure FINAL FANTASY EXPLORERS released today. The title includes a variety of unique and memorable eidolons from the FINAL FANTASY series, including Bahamut, Ifrit and Ramuh, as well as two brand-new eidolons, the flower-like Dryad and the mysterious Amaterasu.
In FINAL FANTASY EXPLORERS, adventurers can battle the 12 formidable eidolons solo or in a party of up to four players. Once players defeat an eidolon, they are granted the ability to summon them in battle while in Trance Mode, a temporary ability where players can also transform into other legendary characters from the FINAL FANTASY series.
After the main story is completed, players looking for a challenge will have the opportunity to battle aberrant versions of each eidolon which are significantly tougher in battle than their original counterparts and feature a different design.
