But, of course, I do still recognize the different seasons telling their own self-contained story, other than Chibiusa appearing at the end of Season 1, and the bell being heard at the end of Season 3 foreshadowing Pegasus.
Season 1: Dark Kingdom (Queen Metalia)
Season 2: Black Moon (Wiseman)
Season 3: Death Busters (Pharaoh 90)
Eternal: Dead Moon (Queen Nehelenia)
Cosmos: Shadow Galactica, was it called? And Chaos revealed
So, when listing the MVD's, I'd list them in this style. And in this case will include Cosmos.
- Queen Metalia - Destroyed by Sailor Moon blasting her weak point with the Moon Stick. (Season 1)
- Wiseman - Destroyed by Sailor Moon and Sailor Chibi Moon with Moon Princess Halation. (Season 2)
- Pharaoh 90 - Slowly destroyed by Sailor Saturn with the power of the Silence Glaive. (Season 3)
- Queen Nehelenia - Destroyed by Sailor Moon with Starlight Honeymoon Therapy Kiss. (Eternal)
- Sailor Galaxia - Turned to dust when her bracelets shattered on realizing that Sailor Moon embraced and believed in the distant future. (Cosmos)
- Chaos - Destroyed by Sailor Moon with Silver Moon Crystal Eternal Power. Will reincarnate as Sailor Chaos in the distant future. (Overarching antagonist)
But still consider them the same show, just with different seasons and films telling their own story in continuity with each other.
