Characters
Seth Hyperson - Seth is a kid that knows right from wrong, and he uses the Omnitrix to help people (and sometimes to help himself).

Mandy Hyperson - Mandy is Seth's brother. They sometimes get along, sometimes they don't. Sometimes Seth considers her the voice of reason.

Henry Hyperson - Henry is Mandy and Seth's father and tries to keep their alien mother a secret from them. Once Seth found the Omnitrix he knew they had to use it for good and he is sometimes angered when Seth uses it for his own "games".

Liax - Liax is a Transylian who thinks Seth doesn't have the responsiblity to weild the Omnitrix so he constantly tries to destroy him so he can weild it for himself (to get power of course). He is the main villian.
