Well these are my dark side's designs (which looks better)

Eclipsa in her warrior form (it's like the evil queen from ever after high)

Eclipsa making a deal with someone (like Ursula from the little mermaid)

Eclipsa up close

Eclipsa taking control of me (like midnight sparkle from MLP)

Eclipsa in an evil look

Eclipsa being defeated

This is Eclipsa in human form her name is Nissa nightly

So what do you think?
