Wrist controller

The wrist controller is an object that appears in the Sonic Boom franchise. It is a multifunctional tool used by Dr. Eggman as his personal weapon and universal controller for his various inventions.

Appearance
The wrist controller is a magnifying glass-shaped gauntlet with a grey frame. Inside the "lens" section (the touchpad) and down inside the "handle" area is a glass-like interface. It also has two metal straps for Eggman's wrist and upper arm. Originally, its interface was orange, but it changed to blue after Eggman incorporated the device taken from Lyric.

Features and abilities
The wrist controller is manipulated via touchpad or voice command. It can fire various beams, like lasers potent enough to incinerate smaller objects, beams that encapsulate victims in force fields that can only be lowered by the wrist controller itself, and beams that teleport targets. It also has an alarm for scheduled tasks and a music player.

After equipping it with a device from Lyric the Last Ancient, the wrist controller gained technopathy abilities, enabling it to control virtually anything electronic around it as long as it is not manually controlled.

Sonic Boom: Rise of Lyric
In Sonic Boom: Rise of Lyric, Dr. Eggman wore the wrist controller throughout the escapades involving Lyric the Last Ancient. After Lyric was defeated, Eggman salvaged Lyric's technopathy device and incorporated it into his wrist controller.

TV series
The wrist controller was always worn by Dr. Eggman as a part of his standard attire. At times, Eggman used it to battle Team Sonic's members in person, commit evil or handle minor annoyances. Other times, he used it to command his various inventions and weapons, coordinating his robot forces, control the inner workings of his lair, and for more novel situations like providing music or remembering his laundry. However, there were times where Eggman could not control its technopathic function, like when the first iterations of Obliterator Bot and Giant Robot would not respond to it.

Archie Comics
The wrist controller was always worn by Dr. Eggman as a part of his standard attire (and alternate ones). However, he has of yet gotten around to use it.

Sonic Boom: Shattered Crystal
In Sonic Boom: Shattered Crystal, the wrist controller appears as a part of the toy from Q-N-C's Toy Shop that depicts Dr. Eggman. Curiously, it is depicted with a yellow interface, like when before Eggman incorporated Lyric's device into it.
