Spider-Man Origins Doctor Octopus tentacle pincers.
Marvel Legends Sinister Six boxset Doctor Octopus tentacles.
The hardest part here was definitely dealing with the tentacles. These things were a bit of a chore to make to be honest. The Marvel Legends Doc Ock comes with 3 pincers per tentacle, but Lady has 4. So I had to get a couple of Doc Ocks to get enough pincers. Also, Carolyn has a pointed end to her pincers rather than Otto's gripping style, so those needed replacing.
The Marvel Legends Doc Ock also had those more modern sucker-designs along his arms, so to keep with Carolyn's more classic look, I used the plainer tentacles from the Sinister Six Doc Ock.
Attaching these into the body was also a pain as I had to be careful not to drill through any of the internal joints that would've hindered her articulation.
