D-Fekt

D-Fekt, originally named RagnaBot, is the primary antagonist in Sonic Boom: Fire & Ice. Originally a mining mech created by Dr. Eggman, he had a malfunction that granted him powers beyond his intended purpose. Eager to prove himself, D-Fekt sought the defeat of Sonic the Hedgehog, but wound up in Sticks the Badger's care.

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

Appearance
A rather small robot, D-Fekt is similar to Orbot and Cubot in terms of facial features, possessing the duo's general face design (except for a lower jaw), cyan mouths and cyan eyes. Other than that, D-Fekt has an orange, black and tan color scheme, a tall head and a rather small humanoid body by comparison. His four-fingered hands and forearms are overall more armored than the rest of him. He also has round shoulder pads, simple and small legs, two caps on his head resembling ears, and a grey slot-based screw cap on his forehead.

Sonic Boom: Fire & Ice
Created as "RagnaBot" by Dr. Eggman in Eggman's Lair, D-Fekt was designed to extract Ragnium from Ragna Rock for Eggman's EggBot Racers using magnetism. Hearing Eggman's premature praise of him upon his activation, RagnaBot was smitten with affection for the doctor. However, RagnaBot failed his testrun when his malfunctioning magnets could not attract Ragnium, prompting Eggman to rename him "D-Fekt" in contempt. However, D-Fekt secretly learned he could magnetize everything else to gain more power, and so sought to defeat Sonic to regain Eggman's love.

Although D-Fekt was but a failure in Eggman's eyes, he was made one of Eggman's Island Defenders tasked to keep fissures open so the by-products from Eggman's operations on Ragna Rock could piped through them, lest Ragna Rock would explode from the pressure. In an attempt to keep Sonic and Amy from sealing fissures, D-Fekt got the attention of Team Sonic. While D-Fekt would escape the heroes, his failed attempts to stop them earned him more criticism from Eggman.

D-Fekt would subsequently travel to other islands' fissures, with Team Sonic hot on his heels and sealing the fissures he protected. Along the way, he met Sticks the Badger and the two would develop an affection for one another. D-Fekt was eventually captured by Team Sonic for tests, and though he escaped, Team Sonic got him to wear a tracker which they used to follow D-Fekt to Ragna Rock. There, D-Fekt showed his powers before Eggman when following the doctor's orders to destroy Team Sonic when they arrived. However, D-Fekt went overboard and ended up destroying Eggman's Ragnium mine before he was defeated by Sonic and Sticks. Afterwards, D-Fekt was given to Sticks by Eggman in reluctant gratitude towards Team Sonic for saving his life in the mines, and Tails reprogramed D-Fekt into a harmless mech.

Personality
A silent and diminutive robot, D-Fekt is fiercely dedicated to his assignments and his goal of defeating Sonic. However, he is very clumsy and when he finds himself in a pinch, he will not hesitate to run away.

Powers and abilities
D-Fekt is the most powerful mech ever created by Dr. Eggman, having been described as "unflinchingly powerful." Supposedly, not even opponents of Knuckles' caliber is a match for him alone. D-Fekt is equipped with powerful eco-magnets which were intended to magnetize and move around Ragnium. However, a malfunction enabled him to magnetize everything other than Ragnium, from artificial structures to substances of organic origin. 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 with enormous raw strength and durability. These constructs also possess destructive powers depending on the material used in their construction, from generation of organic substances to channeling of pure elemental forces of nature.
