A Ultimate X is just like an organoid but it isn't. A Ultimate X is a Zoid with a permanent bonded organoid, That lets it learn as it battle. It learns as it wins and as it is defeated. By analyzing all combat data from the previous battles that it has either been defeated or has won, the Ultimate X zoid can predict the move of the warrior. The one disadvantage of this organoid is that it can not switch zoids it has to always stay in that one zoid. There aren't many zoids which have permanant attached organoid systems, there are only four or five zoids that appear in all three series: Deathsaur, Death Stinger, Liger Zero and Beserk Fury.
