- The XL-4 processor is a technological marvel of modern computing from the Transformers Animated continuity family.
The Tutor Bot has an XL-4 processor processor for a brain. Though primitive by Cybertronian standards, it is still quite advanced for Human created technology. Tutor Bot claims that it is more advanced than the brain of a dinosaur.
This claim is somewhat debatable, as it does not contain any self-preservation programming.
