the line had LT.Stone in it.when i first saw lt comming to s6.it was like mabe it was a door to opining Extreme . but both joes had nothing of the same backround.

Shoot, you got me...yeah, Batman was a hit...but that's was due in part to the movies and cartoon, after Kenner got the license back from Toy Biz.
Still, it counts.

Even if the line was 99% Batman figures, none of which ever so much as had a knee joint.
