I guess Spoilers ahead for anyone who hasnt seen the series but I doubt anyone reading this hasnt seen the classic series but putting it here anyway so turn back if you havent?
So im rewatching the classic series and I know the Omnitrix is meant to scan alien forms and store their DNA in the Omnitrix (as seen with the wolf alien later in the series) so im just wondering why it hasnt been scanning all of the aliens Ben has encountered thus far? Like the small electric aliens (im bad with names lol) in the small town (they were stored in the rubber band ball until Ben broke them out with Four Arms) or in the episode ive just watched, the Alien God dude in the Mayan Temple, or even some of the Aliens when Ben and Kevin got sent to the entertainment ship and were forced to fight together?
