Orange the hedgehog shares the speed of sonic ,the intelligence of tails, the strength of knuckles, and the anger of shadow (sometimes)
Orange the hedgehog was made by ivo robotnik to be better than shadow and his other creatsons,but was a failed project because he had a more anger side towards him,so ivo robotnik decided to kick him off the spaceship in a capsule,towards earth
Orange the hedgehog could defeat eggman alone,he had to think of a plan that used all of his abilities, the speed, the strength, the anger, and the intelligence,the speed was for out running eggman's attacks, the strength was to defeat eggman faster than sonic would, the anger would motivate him to do it for revenge, and the intelligence was to be able to calculate how long it would be for eggman to attack again.
