In "The Batman's Last Christmas!", from March 1982, Batman teams up with Earth-2's Huntress, Helena Wayne. Batman is shaken by evidence suggesting his father, Thomas Wayne, secretly bankrolled a crimelord. This discovery leads Batman to question his entire crusade. With Huntress's help, he uncovers a deception, restoring his faith in his father's legacy. This issue is notable for its poignant holiday theme and the rare, impactful team-up between these two Bat-family members, exploring a profound emotional challenge for the Dark Knight.
