they never show but they show when sonic meets tails, but you can go to Google and go to videos and write how did sonic meet Amy and mabie they show ya.
obviously SONIC THE HEDGEHOG!
I do believe that the first episode they appear in is episode 39, "Defective Detectives", when they introduce themselves. It's a good episode, it really is, at least in my opinion, because Team Chaotix is my favortie team and has Espio, the best in Sonic X. ((just in my opinion.)) You might look Defective Detectives up on Wikipedia, unless you'd rather watch it first.
Shadow first appears in episode 33 of Sonic X. Shadow makes his last appearance in episode 38 of Sonic X.
She was in the very first episode.
They are acuainted before the start of the series, as they know each other already in the first episode.
Tails use to have a girlfriend called cosmo but she died, so no he doesnt have one Cosmo wasn't his girlfriend the potion made Cosmo and Tails in love but since Cosmo died he has to move on and go with Amy since he liked her first before he met Cosmo but Cosmo liked Tails Tails really likes Cosmo as a friend the potion just made Tails "love" Cosmo, those 2 aren't really in love but Cosmo really loves Tails
