Miles "Tails" Prower (Sonic X)

Throughout most of the anime series Sonic X, tails mirrors his game role in various stories and game adaptions, though he sometimes plays a smaller role than Chris Thorndyke. He quickly befriends fellow inventor Chuck Thorndyke, who helped him build the X-Tornado jetplane.

In Series 2 (Series 3), Tails falls in love with Cosmo, the plant-like alien girl introduced in Series 3, starting in Episode 62 when they both get lost together in the underground cave of the Metarex. This is als shown in Episode 65 when Vector and the rest of the Chaotix attempt to play match-maker between the two of them. In the end Tails quotes "You're so beautiful, Cosmo," however, Cosmo remains idle and says "Yes the stars are beautiful. We should just stand here together and gaze at the stars forever, isn't that fun?" In episode 69 Cosmo is asked by Amy how things are going with them but Cosmo embarassed changed the subject to how Amy and Sonic's love relationship was going. Their love for each-other is comfirmed when they fell into a love spell trap that Amy had set up for her and Sonic. In episode 70, Tails loses his morale and Cosmo encourages him to come back after which he succeeds in saving everyone from the Metarex. The strength of Tails love is shown in Episode 73, where Shadow, in an attempt to kill Cosmo, clobbers Sonic, Chris and Knuckles, but, despite his best efforts, could not manage to get past Tails, who was determined to protect Cosmo, no matter the cost. Unfortunately, Cosmo ssacrifices herself in Episode 77, fusing herself with the Metarex planet so that Tails could destroy it with the Sonic Driver. Tails was extremely hesistant to fire, and only did so at the urging of Dr. Eggman and Cosmo herself. In Episode 78, Super Sonic and Super Shadow use "Chaos Regeneration" to try to bring Cosmo back to life, but only manage to produce a seed. When Sonic shows the seed to Tails; the fox collapses with grief. However, Sonic and Shadow succeeded; at the end of the episode, the seed begins to sprout.
