There was a discussion a few months ago about Lotor’s hands how they go from regular to having claws in some scenes. We see it again up close in season 4
In the scene where he wake up from being stunned, we see that his hands clearly don’t have any claw-like features. Specifically looking at his thumb. But in a next shot only seconds later, he suddenly has the sharp claws:
This can’t be an animation mistake since it’s happened before when they did close ups on his hands. My theory is that maybe, just like some animals, Lotor’s claws only show up when he feels threatened? I feel like it may be emotions that trigger this change or actually, it could be a conscious effort to make himself even more capable of defending himself if the situation comes to it.
We know Haggar has those claws but Alteans don’t have any sharp nails. But we see this in the 3rd episode:
Her hands are the only thing that seem to be consciously changed to have a Galran appearance. It seems to me that the claws are a signature Galran aspect of one’s appaerance and maybe Lotor is able to chameleon himself like his mother? Maybe the claw thing is a conscious change when the situation calls for it?
