All the characters are the same but with different looks; there is a new character called Laura though that helps jeremy in the lab. The characters are meant to be the same, but the real actors are not the same as the animated ones. Animation is so...perfect...real life on the other hand is not perfect. That's why there are noticable changes, but for Aelita's Mom--Really MoonScoop? MoonScoop could have found an actress that would willingly dye her hair and would reasonably meet a height requirement. Their attitude is not acceptable toward this show.
