Comparison with original Lego figure on right:
2) Scarlet Witch. The colour of the eyes is not red on the alternate face.

5) Hulkbuster Iron Man - Mark 44
[Please ignore the location of thrusters at the back the original build on right. I don't know why it's there. It's supposed to be on the 2 x 6 plate.]
