No. “Glinching” is common place in GALIDOR. Anyone can swap limbs with each other, in some instances without the other party even consenting.
What makes Nick so special is that he doesn’t have to swap with anyone. Using his abundant “glinch energy” he can basically change and create new matter from scratch. Nick’s father and Allegra do not have this ability, they’re just normal humans. This is what makes Nick so important to both parties in GALIDOR. It is assumed that this ability was inherited from Nick’s mother, the queen of GALIDOR.
Gorm, on the other hand, has the ability to create illusions. Sometimes these illusions have mass, like some variants of the Boge. I’m not sure if Gorm’s illusion abilities are from the small portion of glinch energy he stole from Nick as an infant or something he could always do.
I admit the show really doesn’t do a good job explaining any of this. Perhaps intentionally to try and hook the audience with intrigue and mystery. I’m still not entirely sure about the order of events prior to Nick’s arrival to the outer dimension.
