Indigo Asteroid

"Unleash the Cosmos!"

- Sonic Lost World - Colors Trailer

The Indigo Asteroid (インディゴ・アステロイド) is a transformation for multiple users which first appeared in both the Wii U and Nintendo 3DS versions of Sonic Lost World. It is a Color Power gained by absorbing an Indigo Wisp and its Hyper-go-on, which turns the user into an iron ball into a miniature, but dense celestial body.

Appearance
As the Indigo Asteroid, the user turns into a orb-shaped body with striped indigo skin and a matching planetary ring encircling their middle. In Sonic's case, his version of the Indigo Asteroid has his eyes on the front, which have turned yellow and lost their pupils, and his ears on top, which are without his ear canals.

Powers and abilities
As the Indigo Asteroid, the user essentially becomes a miniature planet with a strong gravitational field. The use can create a powerful gravitational pull around themselves which is strong enough to tear all kinds of objects to pieces and pull them into its Asteroid Ring, thereby using the gained mass to increase the strength of the gravitational pull. The Indigo Asteroid also grants the user the ability to levitate, allowing them to move through midair.

Gameplay
In both versions of Sonic Lost World, the player can only use the Indigo Asteroid while Sonic is in possession of an Indigo Wisp. However, transforming into the Indigo Asteroid will cause the Wisp Gauge to start depleting, and once it runs out, Sonic will revert back to normal.

When transformed into the Indigo Asteroid, any enemies and smaller parts of the environment the player touches are broken down into rubble which is added to the Indigo Asteroid's Asteroid Ring. This increases its size and enlarges the area of the Indigo Asteroid's effect, enabling the player to break down objects and enemies that are further away and as well jump higher. Certain obstacles, usually of greater size and weight, requires though that the Asteroid Ring has reached a certain size before it can affect them.

When jumping as the Indigo Asteroid, the player can perform an additional action to float in midair, allowing the player to either drift across bottomless pits, slow down their fall or fly across a large area of the level.

Sonic Lost World
In Sonic Lost World, the Indigo Asteroid appears in both versions of the game. On the Wii U version of the game, the player can exclusively access hidden areas with secret items in the Zones as the Indigo Asteroid by moving into purple orb-like voids. In these areas, the Indigo Asteroid's Wisp Gauge is frozen in place until the player leaves or collects the items.

On the Wii U version of the game, the Indigo Asteroid is first used in Windy Hill Zone 1. The player can transform into the Indigo Asteroid by tapping the icon of the Indigo Wisp on the top right corner of the GamePad screen. The player can move the Indigo Asteroid around by tilting the Wii U GamePad or by using the Left Stick, jump by pressing / and float by pressing/holding these buttons again during a jump.

On the Nintendo 3DS version of the game, the player can transform into the Indigo Asteroid by tapping the icon of the Indigo Wisp on the touchscreen. The player can also touch the lower screen to transform back to normal, though at the cost of losing the Indigo Asteroid. The player can jump by pressing / and float by pressing/holding these buttons again during a jump, and as well press the R button to move faster.

Sonic Runners
In Sonic Runners, the Indigo Asteroid is an Equippable Item which the player can use in the stages. When using the Indigo Asteroid in this game, the player can float by touching it on the screen in addition to breaking down obstacles and enemies on the path.

Trivia

 * The Indigo Asteroid's powers are very similar to the Violet Void in the Nintendo 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 breaks the scenery down and picks it up.
 * It's also similar to a Luiginary Work from Mario & Luigi: Dream Team where Luigi can manipulate gravity and allow Mario to move around within the field.
 * This is the only new Color Power in Sonic Lost World that appears in both the Wii U and Nintendo 3DS versions.
 * Originally, the Indigo Asteroid could only be controlled with the gyroscope controls. However, a patch was later released which let the players control it with the analog stick too.
