The Pink Spikes, also known as the Spike form, is a transformation for potentially multiple users which appears in the Sonic the Hedgehog series. It is the Color Power gained by absorbing a Pink Wisp and its Hyper-go-on, which turns the user into a spiky ball.

The Pink Spikes made its first appearance in the Wii version of Sonic Colors. In this game, it can first be used in Planet Wisp Act 2. In gameplay, while transformed into the Pink Spikes, the player will automatically stick to walls and ceilings when they make physical contact with them, thus allowing them to travel along any surface. To get off a surface, the player has to jump off it and steer away from said surface. The Pink Spikes can likewise instantly destroy any enemy or Black Mound it touches and use the Spin Dash on any surface. In addition, the playable character can use both the Double Jump and the Homing Attack while transformed into the Pink Spikes. This form also makes the playable character invulnerable to damage, thus allowing the player to move over dangerous obstacles, such as spikes, without harm. However, there are sometimes bumper-like obstacle on the surfaces that can instantly knock the Pink Spikes off said surfaces if touched. Also, after utilizing the Pink Spikes for a few moments, the player will be awarded with 3,500 Color Bonus points for each second the Pink Spikes is active.
