Some of Suparna's standard Roc abilities are replaced by stronger versions - Dread Dive replaces Gliding Spike, Blind Vortex replaces Scratch, and Giga Scream replaces Triple Attack. The only differences are an increase in damage dealt, although Dread Dive no longer inflicts Stun. Suparna also has access to the Bard songs Horde Lullaby, Massacre Elegy, and Magic Finale.
Suparna is one of many names attributed to Garuda. Garuda is a large, birdlike creature that appears in both Hinduism and Buddhism. It serves as Lord Vishnu's mount and is the Hindu name for the constellation Aquila. Contemporary representations of Garuda are the brahminy kite and phoenix.
