>>8394464>The inner shoulders look like separate piecesI think you are reading too much into this, the inner shoulders look like seperate pieces to allow the upper arms more range of movement upward.
The shoulders on true transforming Zetas in gunpla, the recent HGUC 2.0 and the MG 2.0, have a different shoulder design, the outer shoulder has to fold up into itself in order to transform, I don see that on the Ka Signature in
>>8394254The only way you could make a Wave Rider at that point is to do a partsformer like the first HGUC Zeta in 2003, you had to pop off parts and reassemble them. I don't know why they would go back to 2003 for this new Zeta.
