SF Saiyuuki Starzinger

The two shows are very much different, but Belamis in Starzinger is basically Oscar from Versailles. In a world of space cyborgs she uses an electric sword and wields it with great dexterity. Only introduced in episode 36 of 73, she is motivated to fight for justice and prove her mettle and thus develops a complicated relationship with the heroes of the show, mostly fighting against them. Her design is obviously inspired by Oscar. 

Sci-fi anime about traveling through space to reach a goal while battling various space monsters and bad guys. They are both shows from the 80s with a cult following, and they're adaptations of classic stories made into sci-fi (Journey to the West & Homer's Odyssey). 

Combat, Drama and Adventuring - (And your occasional share of laughs) Starzinger and Macross shares these entertaining aspects and delivers them to you with their unique 70's and 80's charm that cannot be achieved by modern day anime, whether its in space or on solid ground :o)  

Quite similar drawings, both animes have interesting fights, and both have nice princess :)
