Uncertain; proposed parallelisms include "darken" (to tarnish; make dim; cast a gloom upon; deprive of moral quality; become evil), "Draconian" (a radically stringent Athenian legislator who believed crime was indivisible, and commanded execution for almost all), "Dracula" (the vampiric icon from the Bram Stoker novel which has since penetrated pop and gothic culture), "dragon" (the savage reptile of Teutonic mythology), and a generic extension of "Drake," which is derived from "Dragon." All proposed analyses are phonetic analyses. To borrow from Dementor logic, "darken" would most sensibly apply, Drakken being a doctor of darkening, whereas he cannot be a doctor of dragoning, or drakeing, and only tenuously (the) Draconian. As inutile trivia, Dr. Drakken, originally, was to be titled "Ubel Drakken," the word "ubel" of which is Germanic for "evil." As noted by fan member The Jabberwocky, "Drakken," in some Germanic languages, can translate to "dragon," which is a plausible motivation. This hypothesis is furthered by the fact that, in the episode "Sick Day," Ron misconstrued Kim as having said "dragon" instead of the proper "Drakken;" an allusion, perhaps? As further trivia, the names "(Dr. Dr)akken" and "(Dr. Dr)ew," Drakken's pseudonym and real name, share the first four letters, as indicated.
