Their name origins are Sonic the Hedgehog's Rouge the Bat for Rouge the Gliscor, The specialized, constricted region of a chromosome that links sister chromatids for Centromere the Magnezone, The Self proclaimed King of Dreamland from Kirby for King Dedede the Empoleon, the galaxy goddess from Super Mario Galaxy for Rosalina the Staraptor, the term for a woman who lost her man likely thanks to passing for Widow the Froslass, and no reference at all for Mewtle. The name just popped into my head randomly.
