In both animes the female costars are scientific products very important. In Votoms Fyana is the deadly killing machine (first Melkian Perfect Soldier) while inMei Ou Project Zeorymer Miku is a cyborg necessary for final weapons Zeorymer.
Both women have a love affair with actors.
Both are creations of Toshiki Hirano. The character designs are the same, so also the wicks. I especially love them.
Dangaioh also have a similar story as in Zeorymer. Masato is part of an experiment as are Mia Alice, Roll Kran, Lamba Nom and Pai Thunder. The experiments do differ, because in Dangaioh has a characteristic more of fantasy by the subject of the superpowers.
Furthermore both Dangaoih, like Zeorymer are top experiment robots .
These two shows are both on the darker side of the super robot genre, focussing on the flaws of the hero and the thoroughly broken characters surrounding him. Ayato is distinctly more likeable than the protagonist of Zeorymer, but no less disturbed.
