When using the Crimson Eagle, the user turns into a crimson-colored eagle-like figure. In Sonic's case, Sonic's entire body turns into a large version of his own head which no facial features except his eyes which are now pale yellow and without pupils, his ears which are behind his head and a beak-like appendage in place of his muzzle. Additionally, his two upper quills are spread out like wings, with three pink extensions similar to a bird's primaries.
Powers and abilities
As the Crimson Eagle, the user can utilize this form's wings to achieve flight and soar through the air unhindered. The Crimson Eagle's only known weakness is that it can only be used for a few seconds and requires more Hyper-go-on from Crimson Wisps to be maintained.
The Crimson Eagle can first be used in Desert Ruins Zone 1. In gameplay, the player can only use the Crimson Eagle while in possession of a Crimson Wisp. Transforming into the Crimson Eagle will cause the Wisp Gauge to start depleting, and once it runs out, the user will revert back to normal. To extend its duration, the player has to collect more Crimson Wisps. Also, touching the ground or flying into a wall as the Crimson Eagle will also negate the transformation.
If the player is in an area not suited for the Crimson Eagle, the Crimson Wisp will go dormant (which is illustrated by its icon sleeping), thus preventing the player from becoming the Crimson Eagle.
The player can transform into the Crimson Eagle by tapping the icon of the Crimson Wisp on the top right corner of the GamePad screen, upon which Sonic will transform and take off into the air, allowing the player to pass through the Zone in midair. The player must tilt the Wii U GamePad or the Left Stick to move the Crimson Eagle left and right. The player can also tilt it upward and/or downward to make the Crimson Eagle go up or down. The Crimson Eagle can also do a forward midair dash by pressing /, though this consumes the Wisp Gauge faster. Additionally, the Crimson Eagle will attract any nearby Rings it passes by.
