Indigo Asteroid

The Indigo Asteroid is a transformation used by Sonic the Hedgehog in both the Wii U and Nintendo 3DS versions of Sonic Lost World. It is the Color Power Sonic gains when absorbing an Indigo Wisp and its Hyper-go-on energy. While in this form, Sonic can turn himself into a miniature celestial body with a strong gravitational pull.

Physical Appearance
As the Indigo Asteroid, Sonic's entire body turns into a perfectly shaped orb, which is not much larger than Sonic's full height, that is covered entirely in a striped indigo skin. On the surface of this form, Sonic's eyes and ears can be seen, forming a face, though his eyes have lost their pupils and have turned yellow, and his ear canals have disappeared. He also gains a wide lavender ring, similar to a planetary ring, encircling him around his equator.

Powers and Abilities
As the Indigo Asteroid, Sonic essential becomes a miniature planet with a strong gravitational field, allowing him to create a gravitational pull around himself, strong enough to tear objects and even Eggman's robots to pieces. With his gravitational pull in this form, Sonic can as well pick up the resulting rubble created by this form off the ground through his gravity, and pull it into an orbit around him. Sonic can the use the mass from the rubble to increase the strength of his gravitational pull in this form, allowing him to affect objects even further away.

The Indigo Asteroid also grants Sonic the power of levitation, allowing him to move through midair.

Gameplay
In gameplay, the Indigo Asteroid allows the player to devastate any object or enemy that are touched and collect the rubble to enlarge the ring which orbits the player, increasing the range of the Indigo Asteroid's effect.

Trivia

 * The Indigo Asteroid's powers are very similar to the Violet Void in the DS version of Sonic Colors, in that it pulls in objects and grows in strength with each piece collected. The difference is that the Violet Void destroys everything it consumes, while the Indigo Asteroid appears to break the scenery down and pick it up.
