Jack Black is a character that appears in the Adult VIZ comic.

Both the drawn style of the strip as well as the character are a parody of the Boy's Own -style character who is wholesome but ultimately fascistic in beliefs and actions. There is more than a hint of Enid Blyton in the Jack Black character.

Jack is effectively a young amateur detective who along with his dog Silver seems to spend an eternal summer holiday staying with his Aunt Meg. The time period ranges from anywhere between the early 1920/30s to the present day.

Jack usually ends up getting the miscreants involved arrested on trivial charges and severely punished, often at the savage hands of the community.

Examples of Jack's adventures include:

• Uncovering a Milk hoarding scam involving asylum seekers.

• Exhuming a deceased mans corpse so that he can prove that his child was born out of wedlock.

• Teaming up with a Paedophile priest to expose a teacher who is teaching safe sex to teenageers.(The teacher is then lynched by a mob), then assisting his Aunt in performing illegal abortions.

• Getting a charity worker arrested for holding a charity sale on a sunday and having his guide dog destroyed.

• Torturing a downed German fighter pilot and then betraying his aunt and his country.

• Uncovering an Al Quaida cell after finding out that their leader reads The Guardian newspaper and not the Daily Mail.
