E-21 Ballios (E-21 (ボリオス) E-21 (Boriosu)?) is a character that appears in the anime series Sonic X. It is a mass-produced E-Series robot created by Dr. Eggman and designed for playing baseball.


Ballios has a black metallic body reading the words "Eggs" on its chest and its shoulders bulge out resembling an American football player. It stands on its black feet with silver and purple-colored legs with yellow spots. It also has blue eyes and wears a black helmet with a yellow "E" on its silver and purple colored head.



New World Saga

A team composed of several Ballios robots were once deployed in the Diamond Stadium by Dr. Eggman to take on Sonic the Hedgehog and his friends in a game of baseball, where the winner got to claim the Chaos Emerald that had just been discovered. At first, the Ballios robots' team easily took the lead due to their abilities but the heroes had some tactics that helped them to catch up. Eventually, Eggman activated one of the Ballios' abilities to detach its head and attach it onto Sonic's head, in hopes of killing the hedgehog with its self-destruction, but Knuckles the Echidna destroyed the robot head before it could explode. The rest of the Ballios managed to escape in the ship from where they were deployed while Eggman got away with the Chaos Emerald.[2]


While usually soulless machines, the Ballios robot do possess a limited degree of autonomy, being able to express feelings like frustration or exasperation. They can even get emotionally incapacitated by things like cuteness; when Cream used her cuteness to appeal to a Ballios, it blushed so much that it could barely throw a ball.[2]

Powers and abilities

Being built for the purposes of playing baseball, Ballios is built as an athletic robot, being both excellent pitchers and batters. It is able to extend its arms and legs across long distances to their advantage when throwing or catching balls, and possesses a significant deal of super strength; it can throw accurate pitches moving at high-speeds, bat away pitches across far distances or even throw another Ballios (which each heights 120 kg) up into the air. Ballios also has the ability to detach their heads and attach themselves onto a target with retractable claws and then blow itself up.[2]


Ballios robots appear to be fragile; as seen when Amy threw and batted pitches, they break fairly easily.[2]
