Gnarly is a tech used in Chrono Cross. Learned after acquiring 19 boss stars, Doc uses his chiropractic knowledge offensively to deal damage to a single foe.
Etymology[]
Gnarly is slang for something extreme (used in bad and good cases). The word was popularized by surfers, which Doc strongly resembles both in attitude, fashion, and origin -- since he hails from Guldove, an island that prides on aquatic transportation.
