Patalliro's bodyguards are known as the "Tamanegi". The term "tamanegi" means "onion", due to the onion-shaped helmets the guards wear.
This was the first anime to prominently feature homosexuality. Even though the story is primarily a comedy, it contains themes of "shonen-ai" ("boys' love" or relationships between males) with the main focus on Bancoran and Maraich (Maraich is definitely a man, but behaves like a woman and has a feminine voice actor).
The "Cock Robin" routine was so popular that it became a song appearing in the closing credits.
Voice actress Toshiko Fujita originally tried out a more masculine voice for Maraich, but decided to keep it naturally feminine.
