Lugia Hydro

Lugia Hydro is a major antagonist in the anime, Spirit Chi Warriors!. He is a childhood friend of both Laxus Kanari and Naskudo Kanari, as well as being the arch-rival of the former. Due to the loneliness of having no family, and being born to a rare breed of humans without Sacred Marks, Lugia developes an intense jealousy for Laxus, which eventually grows into pure hatred, which leads him to insanity. Longing for a family to take care of him, as well as to not be discriminated by society, Lugia has made it his goal to get even with Laxus, with the intent on stealing his Spirit Beast, and killing him for good. He is also a major rival of both Kai Szasazu and Yugi Typhoon, respecting the latter as an adversary, viewing him as the most honorable person he has ever met. Up until his death, Lugia has been considered apart of the regular cast of the main characters due to his overall importance to the plot, and how frequently he is around the Spirit Chi Warriors. After his reform, Lugia grows a close friendship to both Laxus and Ryuga Kaiser, who eventually becomes his best friend. Lugia is the founder of the Time-Space Element.

Shadou Luugia/Possessed Lugia
Shadou Luugia/Shadou Lūgia (シャドウ ルギア) is a possessed-state or form of Lugia Hydro. This isn't another entity or spirit like in the cases with Yugi and Ryuga. This form is created from Lugia's own insanity, creating a more psychotic and maniacal state of his own true person.
