Ruby Halbird is an enemy in Blue Dragon.
Description[]
These pinkish variants of the Hawk Eye appear within the Mural Valley East and fight alongside their other half in order to use their Jump Attack move. Take out whatever there is less of first, or the Hawk Eyes as they are weaker, to disable them using their special attack. Also note that they can use a Sonic Boom attack as well as use Dizzy to give you the Dizzy status.
Monster Record Entry[]
"These elite warriors of bird-kind are proud of their glittering golden halberd. They use a Jump Attack when with a Hawk Eye. Fond of shiny things, like most bird-kind."
