Calling humans "fleshy ones" and expressing a degree of pride in his "roboty parts" — which he uses to kill Fin Fang Foom — Aaron has developed a fondness for alcohol, stating "My robot brain needs beer" on regular occasions. He is not especially popular with his teammates because of his self-important attitude, and, as is learned in a flashback that after being brought to space by the Celestials at the conclusion of his previous series, he was dumped back on Earth because the space-gods considered him to be a "complete and utter ☠☠☠☠." ("☠☠☠☠" representing an unspecified, but extremely offensive, profanity throughout the Nextwave series) He appears to have a rather serious attraction to Elsa Bloodstone and stares at her chest constantly, much to her chagrin.
