I have been binge watching it
and I can’t help but make InuYasha comparisons
Naraku and Rumpelstiltskin
Look at Rumple’s outfit when his in the past or in season 3 in his ‘Dark One clothes’ those clothes remind me so much of later season - Final Act Naraku’s wardrobe.
There is of course the obsession with power and losing everything to keep it, but that’s a theme with most bad guys
You also have Regina’s mother who likes being evil and a bad person and see’s love as a weakness, so what is her grand plan? Removing her own heart so she can’t be in love. Where have we seen this plot before?
That heart and those feelings result in her death and wind up in her undoing.
I also have a weird Captain Hook and Miroku comparison going on
Both men who make perverted comments and have issues with their hand
