Samurai Jack: Battle Through Time contains the final video game credit for Dead or Alive series creator Tomonobu Itagaki before his death in October 2025, where he was credited as "Supreme Advisor".

By holding X or Y while using Samurai Fist, Jack can perform two secret animations that act as references to a scene from Episode XXXVI of the original series, where Jack and two Xiaolin monks battle and notice similarities between each other's skills:

• The first animation shows Jack performing the Water Beetle martial arts style.
• The second animation shows Jack turning towards the camera and performing the principal secret sign of the Xiaolin monks (a raised index finger and suppressed thumb).
