Reala ( (リアラ Riara) is the secondary antagonist of the NiGHTS series. Reala, like NiGHTS, is a First-level Nightmaren. Unlike their older sibling, Reala chose to remain loyal to their creator Wizman the Wicked, serving as his right-hand man and NiGHTS' rival/nemesis.

Reala like all Nightmaren is a genderless being, but unlike NiGHTS who has been referred to by male and female pronouns, Reala has almost exclusively always been referred to by masculine pronouns.

Reala has a very similar shape and appearance to NiGHTS. He has a thin, humanoid form, gray skin and large blue eyes with vertical slit pupils. Reala's hands and head are not connected to a visible body, with their body seemingly made only apparent by their clothes. Their outfit consists of a grey unitard. They also wear a red jacket accented with white buttons and black trim, with on his chest is a diamond pattern in blue, purple, and red. A small he wears a blue ruffled collar. Their boots are like their jacket are striped red and black. Atop their head is a red and black, two-horned jester cowl. Unlike, NiGHTS, Reala's cap is slightly longer and more angular. He also wears red and black bracers on his forearms and wears yellow claw like gloves.

In NiGHTS Journey of Dreams, Reala's design is slightly updated. His design is made to be even more similar to NiGHTS with a uniform palette consisting of shades of red for his cowl and boots. Fingerless black gloves instead of the yellow claws. His vest now has black feathers protruding from the sides and he wears a black undershirt wears gold necklace with a red gemstone. He also now wears a belt and shin guards. The most notable change now is that Reala wears a gold mask on face known as a Persona, which is a symbol of undying loyalty to his father Master Wizeman.

Reala has more or less all the same moves as NiGHTS, he can fly through the air, perform a drill dash, shapeshift into various objects/vehicles/creatures, and para-loops to create a black hole effect. He also has the ability to send Visitors to the other Dream Worlds within Nightopia and summon large and explosive meteors to hurl at his opponents in a duel. He can also construct his own Dreamworld consisting of various braziers, a throne, and his seal in the sky. Said world is entirely black and red.

Reala takes on a similar role and relationship to NiGHTS as Shadow the Hedgehog to Sonic the Hedgehog and Jeanne D'Arc to Bayonetta.
