Did You Know?


Before the Japanese trailer was released at the World Hobby Fair (January 2003), there was already a three-minute teaser existing that was created sometime during early 2002, as the collaboration preview between SONICTEAM and TMS Entertainment. Cream the Rabbit was stated as a new character (due to the trailer being released before her video game debut, Sonic Advance 2 (2002), was completed) and Cheese is plainly referred to as "CHAO." This trailer was narrated in English, probably done most to market in some TV network sales pitching. Scenes from the two trailers have been used for the anime's first opening. See more »


Knuckles the Echidna: You're late, slow-poke.
Sonic the Hedgehog: Yeah, well, I stopped to admire the scenery. This planet is pretty cool. You'd like this place too if you weren't such a party pooper.
Knuckles the Echidna: Enough talk. Let's go.
Sonic the Hedgehog: Relax. We got all afternoon to duke it out, buddy boy.
Knuckles the Echidna: I'm not your buddy and don't you forget it, smart aleck! Now put 'em up! I didn't come here to sniff the flowers!
Sonic the Hedgehog: That's your loss. You don't know what you're missing. But if you'd rather get clobbered by me...

Too much Chris, not enough Sonic
3 May 2010 | by (United Kingdom) – See all my reviews

I haven't played the games for a while, but I do remember them being fun, exciting and just great in general. I will say I am a huge fan of Sonic the Hedgehog SatAM, it was very well animated, well written and the stories were always done in a unique, faithful and mature way. Plus you have Jim Cummings as Dr Robotnik, he was amazing as always. However, I was really disappointed in Sonic X.

It started off brilliantly, with a wonderful first couple of episodes, good music with exception of the theme tune and a great concept, and then it all went downhill just like that.

My first major problem with Sonic X is that the characters are not well-developed. That is with the exception of Chris, but the thing is there is too much of him, and not enough of Sonic and everyone else. Sonic in the SatAM series had a personality, and a unique one at that, but that personality doesn't come across here. And later Chris gets really annoying and obnoxious. Secondly, the animation quality is uneven, in the first episode it was fine, but as the series progressed it became jerky, rushed and lacking in crispness and vibrancy. Thirdly, the story lines are not as well thought out or as gripping, some of the episodes here are poorly structured and even have major contradictions to the games. Fourthly, while I liked the incidental music, the theme tune I did not like, I for one didn't find it catchy or memorable and later it even got annoying. Fifthly, the writing lacks intelligence and verve, the villain Dr.Eggman(or shall I say Dr Robotnik) especially has some lame dialogue that didn't make sense. Finally, I didn't find the English dub voice work that great, the actors try their best with superficial material but with the characters so underdeveloped nobody stands out.

Overall, disappointing, started off great, but as the show progressed the flaws became increasingly abundant. 3/10 Bethany Cox
