Duck Avenger has been modified during the years, both from his original character of dark masked avenger and from the type of his stories. There have been three main versions of Duck Avenger of course each with some various due to different writers and story types.

We can analize the typical characteristic of these three Duck Avenger versions and their positive and negative aspects.

Duck Avenger, the devilish avenger (Guido Martina, partially reproposed by Fabio Michelini, Francesco Artibani, Carlo Panaro)

Character type: Mysterious self-avenger, heir of the gentleman thief Fantomallard, enterprising and active, very skilled in the disguise. He is very keen and smart to unmask his enemies or rivals which he often punishes in a light sadistic way.

Positive aspects: He is the protagonist of long and charming stories. He is the original Duck Avenger who takes reference from the classical dark and worrying characters of literature such as Fantomas, Arsene Lupin, Diabolik etc... He looks credible as Donald's alter-ego.

Negative aspects: His first stories are now considered a little bit out of the Walt Disney "politically correct" rules. He acts sometimes at the border (and sometimes even out) of the law and in some stories he also becomes Scrooge McDuck's personal avenger-mercenary.
In almost all of his adventures he fights against the same adversary: Rockerduck, Gladstone, the Beagle Boys and Scrooge.

Duck Avenger, the hero law enforcer (Concina, Pezzin, Chierchini, Sarda ecc..)

Character type: Idealist with no spot on his reputation, champion of the oppressed people, goodness avenger who serves the community, he is sensible to the social problem. He has good will but sometimes he is goofy and clumsy.

Positive aspects: He can be easily placed in several stories types refering of social justice helping awareness in the younger generations.

Negative aspects: Most of his stories are banal and boring. He is too often grotesque and ridiculous, in the archaeological version he looks silly and out of place while, in exotic countries, he explores jungles and ancient temples wearing his black costume during the day! In the superheroic variant he doesn't look credible as Donald's alter ego.

PK, Futuristic sci-fi super hero (various authors)

Character type: Super hero human being and galaxy defender, hyperactive and skillful user of the most technological advanced devices.

Positive aspects: His stories are well made with a charming computer-graphic (even if the second and third series PK2 and PK are considered to be of less quality than the first one PKNA). This is an innovative comic respect to the classical Disney production and it is read by a widespread public audience. The character is indicated for the realisation of gadgets, toys and videogames.

Negative aspects: He is Donald who acts who knows why or when in a completely different universe from the Disney classical adventure one. Even if he doesn't have storical continuity with the classical Paperinik he uses the same costume and in the beginning the same name.
His image is nevertheless to much related to the original Donald who obviously reminds of the classical Disney universe. Having a dedicated comic serie PK, once the fashion of the cyber-futur-superhero is gone, the character could be bypassed ( as already happend to the comic Mickey Mouse MM and the first two series of PK: PK New Adventures and PK2), by more innovative and in fashion series like the recent Italian Disney comic Witch.
