Season 1: 1999Edit

This season picked up a short time after the events of the third season of Beast Wars. Four of the six main characters from the previous series/season, Optimus Primal, Rattrap, Cheetor and Blackarachnia, are on Cybertron with no memory of how they arrived there and why they are being pursued by hostile Transformers. These characters try to discover what happened to themselves and to Cybertron and what the ancient computer the Oracle has in store for the characters. There are noticeable information gaps and characters missing from the previous series that are addressed throughout the season. New characters are brought into the cast.
