Rickert possesses a gentle, rational, and somewhat childishly innocent personality, a notable contrast to the typical rough demeanor of mercenaries. Observant and perceptive, he accurately assesses situations, such as attributing responsibility to Corkus for instigating a fight with Guts during the Battle of Doldrey, leading to the loss of men. Rickert's distinct character is highlighted during a celebration marking the end of the Hundred Years War, where he feels overwhelmed by the attention of admiring women who find his cuteness endearing. His initial idolization of Guts for saving him in the Band of the Falcon's early days evolves into a genuine friendship, despite Guts preventing him from joining his journey due to Rickert's inability to harbor hatred towards Griffith. Rickert forms a brotherly bond with Pippin, rarely seen without him, and extends a similar connection to other band members. Beyond his personality, Rickert's intelligence and engineering skill shine through, evident in his creation of the Cannon Arm for Guts and his role in upgrading Guts' arsenal upon his return. His apprenticeship under Godot further refines his blacksmithing abilities, showcasing Rickert's multifaceted contributions within the Band of the Falcon.
