Aquaman Shrine, and I just had to laugh. What a mashup! The Superman/He-Man one at least made sense considering the early MOTU comics, and the Lex Luthor Skeletor one was a natural extension of that, but this is silly.
The truly ironic thing is that of the two sets I am more likely to buy the Aquaman/Mer-Man one -- I already have the Hawkman toy, and Mer-Man is a favorite of mine! Go figure! Of course if they had packed Hawkman with the super-awesome Buzz-Off instead of Stratos, I'd be all over that like a frog on a lily pad.
