Tails is the loyal sidekick to Sonic. He loves mechanics and science but is humble and innocent, the opposite of Eggman. Tails is also very intelligent and acts kindly to others. His best human friend is Chuck Thorndyke; the two create mechas together including the X Tornado. Tails has also been shown to be rather shy and he often had little confidence in the beginning of the series as he depended on the other characters such as Sonic to help him at the times of need. Due to his timidness, Tails was often overshadowed by the other characters as he can be seen often keeping quiet as the other outspoken characters got their ways in discussions. However through the series, Tails soon gained more courage and developed more leadership skills, which was especially seen in the 3rd season where he was the captain of the group (being the owner of the Blue Typhoon) and his love for Cosmo furthered his courage.
Tails can fly using his two tails in a similar way as in the games and when he was defending Cosmo from Shadow he managed to maintain against his much more powerful enemy, even to the point of being injured severely.
