Nick Chopper could be considered a tragic figure. He’s a man who, piece by piece, had all his human parts replaced with tin substitutes. A witch enchanted his axe and it chopped off his parts. A tinsmith fashioned replacements for the missing limbs. Eventually all of Nick got excised and he became a completely tin man.

In the original Oz novels Nick is pretty satisfied with that. He felt the lack of a heart for a while but the Wizard gave him a suitable substitute. There’s no tragedy to that version of Nick. He and the Scarecrow hang out, often congratulating themselves that they aren’t subject to the need to eat or sleep or breathe like ordinary meat people.

The Nick in Oz Squad? He’s had a few more bumps than the Nick in the original novels. He doesn’t seem to miss being human much more than the earlier Nick did. At least not most of the time.
