- This card's name is derived from the Greco-Latin word tragoedia, whence the English word "tragedy". The original Greek word τραγωδία (tragoedia, literally: "goat song") refers to the dramatic plays characterizing seriousness, sadness, and tragic heroes.
- The Chinese name (悲愴魔) literally means "tragic demon".
- This card has a lot in common with "Yubel".
- It is a Level 10 DARK Fiend with no ATK and DEF.
- Just as Yubel hospitalized Jaden's friend Osamu in the anime, Tragoedia leaves Koyo Hibiki permanently comatose as a form of Penalty Game. Both Osamu and Hibiki have influenced Jaden's passion for Dueling.
- Yubel and Tragoedia's bodies are both destroyed prior to the start of each canon, forcing both to (parasitically) depend on humans to do their bidding and recover their true forms. Furthermore, the identities of both are kept shrouded in shadows for much of their story arcs.
- This card's first effect of Special Summoning itself from its hand could be a reference to Tragoedia's creation in the manga; by the hatred of a man when he learned what happened to Kul Elna.
- This card's third effect of gaining control of opposing monsters could be a reference to its manga counterpart's ability of possessing other people.
- This card's OCG/TCG artwork is taken from Yu-Gi-Oh! GX Chapter 31: "Darkness on the Move!!", specifically from the panel where this monster fully reveals himself to the Egyptian priests.
