Similar to the relationship between the 20 Back and the 21 Back the 32 Back only introduced one figure, but it was an important one, Yoda. Some say Yoda was released later to keep the character secret, others say there were production issues. It is worth noting that Yoda is rather haphazardly added to the 31 Back cardback instead of looking like a planned part of the line.

Just like the 31 Backs, there are 2 versions, 32a & b with no offers related to the release. The cards are very similar to the 31 Back except for the addition of Yoda, the consolidation of trademark usage and different toy pictures.
