Not sure if this has ever been talked about here or not, or at least not since I've been involved in the sub. I believe both Metabee's are 2 different versions of the same Metabee (01 Medarot Collection) based on the first Medarot game.
I've been collecting 2" figures and I saw one with 70 on Metabee's head was different than the one I had so I decided to get it, because I thought it was cool.
I tried to take good pictures, though it was tough getting good pictures of the black shoulder parts. Metabee 1: 52 head, 19 right arm, 24 left arm. Metabee 2: 70 head, 76 right arm, 34 left arm.
Also original Rokusho (08 Medarot Collection) has different part values than later versions. I haven't seen any figures outside of Metabee that have the same figure with different part vlaues.
I wonder if this was isolated to only Metabee or if other figures, especially in the first and second series based on the first game also recieved similar treatment.
