E-101 Beta (Ｅ－１０１ "ベータ" E - 101 "Bēta"?) is a character that appears in the anime series Sonic X. It is a robot created by Dr. Eggman, and the first unit in the Doctor's E-100 Series. Beta, along with its brethren, were created during the Chaos incident to aid the doctor. After failing its first mission, Beta was rebuilt into E-101 "Kai".
E-101 Beta was a humanoid robot colored in black and white. It possessed no neck, its head and torso coming together in an almost ellipsoid shape. Its torso was black with a wide and white vertical stribe down the middle, and possessed a head light with a hexagonal gray frame on the right side. It also had gray mufflers surrounding the pelvis area, and had the number "101" painted in white on the right of its large vertical stripe and the left side of its rear. Its head meanwhile was small and platform-like with a yellow shade and green cylindrical eyes. It also had a hexagon-shaped disk hovering behind its neck.
Beta's shoulders were black vertical cylinders. Attached to each of them were Beta's arms, which were long and designed with two joints; each of Beta's forearms were designed as black gun barrels. Also, Beta's upper arms were black, while the parts between its upper arms and forearms were gray. Beta also possessed two long and inverted legs with five points of articulation and large, black feet with two sharp toes and roller wheels on the heels. The upper sections of its legs in particular were black while the rest of them were gray, except from its calves, which were thick and black.
E-101 Beta, along with Gamma, Delta, Epsilon and Zeta, were created by Dr. Eggman as a part of the Doctor's new line of E-Series robots; The E-100 Series. Each of these four used small animals as batteries (Beta himself received a gray bird). Upon its activation, Beta was given a shooting-range test, which it passed with flying colors, before being given its codename.
Beta and the rest of its brethren were soon after assigned by Eggman to find a frog with a tail, which was essential to Eggman's plans. After departing, Beta found what it thought to he the frog Eggman sought, and returned to the Egg Carrier. Back onboard with the crew however, it was revealed that Beta had gotten the wrong frog, much to the anger of Eggman. When it turned out that only Gamma had gotten the right frog, Eggman had Beta, Delta and Epsilon discarded as punishment for their incompetence. Beta himself was quickly relegated to an Egg Carrier robotics lab. There, Beta underwent a torturous remodeling operation into the more powerful E-101 "Kai" where it was physically dismembered and its old limbs were discarded on the floor while mechanical arms worked on it. In the midst of this process, Gamma stumbled into the lab and saw the operations on Beta. This horrible sight served as the breaking point for Gamma that set him on the road to apostasy, eventually making him betray Dr. Eggman and delete him from his master registration.
E-101 "Kai" would be completed after the Egg Carrier crashed. While onboard the abandoned ship, E-101 "Kai" came across Gamma, who was now on a crusade to "rescue" his brethren from Eggman's control by shutting them down, and attacked him. During their death match, Beta and Gamma took each other out at the same time, resulting in the release of their bird batteries.
Lacking in overall autonomy but possessing a degree of emotional capacity, Beta was best defined by its loyalty to Dr. Eggman, whom it only sought to serve, as per its directive. As such, it followed Eggman's orders without question. However, it was also shown to fear Eggman's wrath.
Beta was not necessarily very bright, easily believing the first frog it found to be the one Dr. Eggman searched for.
Powers and abilities
Beta was equipped with twin missile launchers and possessed excellent marksmanship skills. It was also equipped with a hover disk on its back that granted it the ability to fly.
- Like the other E-100 Series robots in Sonic X, Beta's voice was very high-pitched and, according to fans, unenthusiastic, as opposed to in Sonic Adventure where the robots spoke in a manner that, while still being slightly robotic, was very intelligent and much more human than drone-like.
