While it is not known if these Personas grant powers or are simply cosmetic, both Reala and NiGHTS own a personal Persona they are intended to wear at all times. Reala's is always present but NiGHTS' shown only a few times.Reala's Persona is gold with a "vine" like pattern and a pink jewel in the center, the edges are trimmed with black feathers. Three spikes poke up from above the jewel (see the right side of the image above next to NiGHTS).
The Persona we can assume is NiGHTS' personal Persona is also gold but with a red gem in the center and two blue feathers sticking up in the center above the jewel (see the left side of the image above next to Reala). NiGHTS is seen in this Persona only a few times:
- When showing off for Helen in the "world of glass"; this is the only time NiGHTS puts it on voluntarily.
- Placed on their face after being captured by Wizeman, in all endings.
Certain Persona Masks can grant NiGHTS the ability to transform, giving them shapes beyond their natural shape-shifting powers.
Gained after each child's first Nightopia, this persona gives NiGHTS the ability to swim in the shape of a dolphin.
Gained after the second Nightopia, this persona allows NiGHTS to blast off at full speed in the shape of a rocket. This is also effective during the second fight with Cerberus to reach the middle head quickly.
Gained after the third Nightopia, it allows NiGHTS to resist wind and keeps them from floating down when idle as a long-bodied dragon.
- In early 2007, there were rumors that NiGHTS: Journey of Dreams would get ported to the Xbox360 and Ps3 or that a new game tittled NiGHTS - Twilight Adventure would be developed for the later consoles, the game would feature three exclusive masks called "Cloud", "Eagle" and "Magnet", however, the the rumor came from the beggining of the game's development and more news about it never came, meaning it could be either false or the idea was disconsidered. 
- The name of the Persona Masks comes from the word "persona"
