Note that the actor that played Obie (Jesse) was originally meant to play Silas (see script). Guess who was first cast as Obie? Everyone's favorite actor: Timmy a.k.a. Odor boy.
The idea was that in the not-so-distant future, Odor boy becomes the director of the Ultrakids headquarters (with Laserboy still the primary leader). Now that he's an adult, he changes his name to Obie (O.B. Odor boy. Get it?).
But when it came down to it, Timmy wasn't available to film his scenes (which is why he has one quick cameo at the beginning and not a major role). So we quickly switched actors, erased Silas, and merged him with Obie.
One of the random facts about the movie which is completely useless information, but now that you've read it you'll never forget it. :)
