Bio
Anything is possible in dreams.
NiGHTS is a resident of the dream world Nightopia, where he spends time playfully flying through the air, performing acrobatics, and playing an invisible flute. He is a androgynous being whose appearance and abilities can change depending on a given situation, such as morphing into a bobsled in a snow area and a dolphin when underwater. While usually kind and chivalrous, he is also a bit of a prankster, playing jokes and startling people. He is also a 1st Level Nightmaren; a creature created by the ruler of the realm of Nightmare, Wizeman.
NiGHTS rebelled against his creator after Wizeman tried to take over Nightopia, the uptopian dreamscape that exists as a paradise for people while they are asleep. After dissent, he was imprisoned inside the Ideya Palace, a cage who's barrier can only be passed by someone who holds Ideya (colorful orbs representing aspects of human personality).
It is at this point that, in the town of Twins Seeds, two children start to have nightmares. Claris and Elliot fall alseep and imagine their worst fears before happening upon the realm of Nightopia. Both of the dreamers find NiGHTS imprisoned, and since they have retained their Ideya, can help him escape. The dreamers "dualize"( become one) with NiGHTS, regain the power of flight, and take on Wizeman and his henchman for the fate of Nightopia.
NiGHTS has a complicated relationship with the other 1st Level Nightmaren, Reala, whose abilities are nearly identical to his own. While NiGHTS is curious and playful, Reala is cold and obedient, never questioning Wizeman's orders to imprison his equal and capture Nightopia. Reala is second in command underneath Wizeman, and proves to be one of the most difficult challenges to overcome.
With the design of NiGHTS, Sonic Team deliberately made the character androgynous. According to Takashi Izuka: "He is a mirror of the child's personality, so when the children dream, they become him. So from a boy's point of view, NiGHTS will be a boy, from a girl's point of view, NiGHTS will be a girl". Assignment of gender, such as this bio, are merely reflective of the assignments a person has put on the character themselves.
