Born and raised in Boston, Canada, Tails Checkers the Fox (labeled as the Scout) is a two-tailed scrapper fox running at fast speed with a snarky 'in-your-face' attitude and a baseball bat. He is very rude, and seems to think he can handle anything. He often acts a lot tougher than he can actually prove to be, though he's definitely not weak. He is the older brother of Cream Checkers.
Being a speed-type character, Tails is one of the fastest classes in the battlefield. Unlike other speed-type classes, though, he is capable of double jumping, allowing him to reach higher places, ambush enemies from above, and most noticeably, to keep slower opponents, especially power-type characters, struggling to catch up with him. Tails carries with him a Scattergun, Pistol, and Baseball Bat, which are real ideal and strategic weapons usable for flanking, combat, and executing ambushes. Being speedy, Tails is an excellent mercenary used for sapping his opponents, due to his ability to dash in, cause damage with his weapons, and escape before being noticed, and more importantly, left vulnerable.
- Tails is the only 'offensive' class that does not manipulate a Shotgun (excluding his Scattergun).
- He is one of the three Canadian classes in the series, with the other two being his sister and Knuckles.
- Even though Tails and Cream are siblings that share with each other a strong love, Tails's personality is totally opposite in comparison with his sister's. One well-known fact is the way Tails is depicted as cocky and smart-talking, while Cream is shown as kindhearted, polite, and well-mannered. Despite this, as mentioned from the first sentence, the two of them have no hard feelings for each other and respect each other as caring as normal.
