Sonic X in Japanese

Just today, I have uploaded episode 1 of Sonic X in Japanese with English subtitles, but what's the difference? I'll name 3 three things:

1. There are swear words.
2. The title is longer and different.
3. More violent and dramatic.

Here's episode 1 of Sonic X in Japanese (this is just a warm-up of what's to come later in the series):

WARNING: This episode is rated TV-PG-L for moderate language.
