D-Fekt

D-Fekt is the primary antagonist in Sonic Boom: Fire & Ice. Originally a mining robot created by Dr. Eggman, he had a malfunction that let him to evolve beyond his intended purpose. He now seeks the defeat of Sonic the Hedgehog.

Concept and creation
D-Fekt's name is a play on the word "Defect," which is a reference to his central defect with his magnets.

Appearance
D-Fekt is similar to Orbot and Cubot (the former in particular), possessing the duo's general body shape and cyan facial features. Unlike Orbot however, D-Fekt has an orange and tan color scheme, his head is much taller with two caps on the top resembling ears, and his four-fingered hands and forearms are generally more armored. He also has a large grey slot-based screw cap on his forehead, no lower chin and two small feet.

Sonic Boom: Fire & Ice
D-Fekt was designed by Dr. Eggman to find and mine his newly-discovered Ragnium element using magnetism. While searching the mystical island of Ragna Rock for the element however, D-Fekt malfunctioned and became able to magnetize everything except Ragnium. With this capability, D-Fekt gained more power and began messing up the environment of other islands with the by-products from the mining operations.

As D-Fekt would use his powers to build himself to beat Sonic the Hedgehog, Eggman made him one of his Island Defenders in preparation for the inevitable showdown with Team Sonic.

Powers and abilities
D-Fekt is a strong Eggman robot, having been described as "unflinchingly powerful." He is equipped with powerful eco magnets which were indented to magnetize and move around Ragnium. However, a malfunction enabled him to magnetize everything other than Ragnium, from tar to dinosaur bones. This allows D-Fekt to draw the environment itself to him and form it into new objects, his most prominent use of this skill being to build himself up to form giant robotic creatures which are powered by D-Fekt himself.
