Fairy

Fairies are a species that appears in Sonic and the Black Knight. They are a race of magical creatures from the world of Camelot and supposedly the world's equivalent to the Chao. They come in a different variety of colors and the type can be identified by the color of their glow.

In gameplay, fairies appear along the way during the majority of the missions in Sonic and the Black Knight, usually in clusters. Touching a fairy will grant the player a certain effect depending on its color, ranging from granting Rings to giving a boost in speed and so forth.

Anatomy
Fairies are very small creatures, not much larger than the size of Sonic's hand. Their body looks like the head of a neutral Chao and they have a pair of wings on each side of their body. They each glow in different colors, glowing either yellow, red, blue, green, purple or white.

Powers and Abilities
Fairies are able to fly in the air using their wings. They also possess skills in magic, which so far allows them to levitate objects.

Types of Fairies
Fairies come in six different colors which marks their type. Those that can be interacted with can grant the player an effect when touched, with the effect depending on the color of the fairy.

Yellow Fairies
Yellow fairies are the most common type of fairies, and can appear alone or in clusters. They grant the player a certain amount of Rings when touched, similar to the Super Ring, and basically replace the Rings in most of the mission. The number of Ring the yellow fairies can grant range from one, two, five, ten, fifteen and up to thirty Rings. The amount of Rings they grant depends on the size of the cluster of yellow fairies; the larger the cluster is, the more Rings it grants. After being touched once, the yellow fairies disappear.

Red Fairies
Red fairies are a type of fairies that fill up a portion of the Soul Gauge when touched, and can appear alone or in clusters. How much of the Soul Gauge they fill up depends on the size of the cluster of red fairies; the larger the cluster is, the more of the Soul Gauge it fills. After being touched once, the red fairies disappear.

Blue Fairies
Blue fairies are a type of fairies whose effects are virtually the same as the Dash Panel and the Spring. When the blue fairies are aligned along the ground, touching them give the playable character an increase in running speed, like the Dash Panel. When they are aligned into the air, however, they launch the playable character through midair, like a Spring. In gameplay, they can be homed in on with the Homing Dash. Usually, blue fairy clusters are set in different sizes of rows.

Green Fairies
Green fairies, specifically called Hidden Fairies, are a rare type of fairies which always appear alone. Unlike most other fairies, these ones do not grant a unique effect when touched. Instead, they are the primary targets during the "Hide and Seek" missions in Sonic and the Black Knight where the player's objective is to find and collect a certain number of Hidden Fairies. With the Skill Hidden Fairy Lock-On, the player can use lock-on on Hidden Fairies during Soul Surge, making it easier to collect them. After being touched once, the green fairies disappear.

Purple Fairies
Purple fairies are a type of fairies whose effect is identical to the Air Launcher from Sonic and the Secret Rings and always appear in clusters. When touching a cluster of purple fairies, the playable character is suspended within it. The player can then shoot the playable character through the air in a linear path by swinging the Wii remote when an image of the Wii Remote appears. Failing to do so will make the playable character fall out of the fairy cluster.

White Fairies
White fairies appear exclusively in Misty Lake where they fly around in the background. As such, they cannot be interacted with by the player nor do they grant a special effect.
