53 a cosmic call
if you mean leave earth then it is 52 chris stopped him from entering the gate in 51
Episode 67.
when he gets really mad because the metarex captured cosmo and chris. This happens in episode 67 of sonic x. by mf842 :)
I believe that in episode 51, Sonic and Chris were hving lunch at a diner. There, they had a hamburger and coke. In episode 10, Sonic had an apple with his dinner.
Chris assumingly went back to his home planet.
sonic did cry ,around in episode 50 or 51 i dont remember, in sonic x when sonic was about to return to his world and when he was taking chris out for his last run with him, you could see some tear drops splashing onto chris' face and it is coming from sonic's eyes and the chris starts crying too.
None of them! Sonic x has NO ghosts in the show.It would just be out of place.
in sonic x you can find it write sonic x episode 18.
In Sonic X episode (around) 32 Sonic defeats perfect Chaos as Super Sonic, and Chaos and Tikal disappear into the sky, after that Chaos is not seen again in the TV show.
Sonic cries in Sonic X episode 52.
If you are talking about the episode of Sonic X where they are filming at a castle, the Episode is "Season 1, Episode 19: Sonic's Scream Test"
Episode 67 Of Sonic X (It's Called Teasing Time.)
