Guest strips Abrams invites other well-known webcomic artists to do the strip for a week once or twice a year, while he goes on vacation. A frequent result is a
parody of the strip itself, other webcomics, other creative works and/or artists, including
Scooby-Doo and
Ayn Rand. Clay Yount of
Rob and Elliot was guest artist several times prior to taking over Saturday duties. Abrams also has various other artists providing art for Saturdays and Sundays, most recently Stuart Taylor and Lauren Taylor of
Chain Bear.
Crossovers and references to Sluggy Freelance in webcomics Numerous other webcomics have referenced Sluggy Freelance, and various guest artists on Sluggy Freelance have included their own webcomics' characters in their guest strips, including
User Friendly who swapped
A.J. for
Torg for a week. Gwynn from
Sluggy Freelance has appeared in the webcomic
General Protection Fault, and Trudy Trueheart, a character from that webcomic, is Gwynn's cousin. The creator of
General Protection Fault said that the crossover doubled the readership of his comic overnight. There are several implicit cross-overs with
R. K. Milholland's
Something Positive, such as a comic where Aubrey was forced to sell her bunny, an aggressive Mini Lop with a love of sharp things, to "Kiki's Petstore". In the webcomic
Freefall, two rabbits are shown and the character Helix names them Kevin (presumably after Kevin Dewclaw in
Kevin and Kell) and Bun-Bun. In the game
Munchkin by
Steve Jackson Games, a monster card for players to fight against has a picture of a switchblade-wielding Bun-Bun. There is a 5 in 6 chance that the monster is a perfectly normal bunny rabbit and a 1 in 6 chance that it is "that" rabbit. Possibly also a reference to the killer rabbit in
Monty Python and the Holy Grail. In the expansion called
Munchkin Bites there is a monster card called "The Evil" which refers to a horror story in the comic. Shortly after the birth of Leah Nicole Abrams in the middle of "The Love Potion" storyline, Sluggy Freelance entered a three-week-long side story. The story involved Ki and Fooker of
General Protection Fault, Lindesfarne and Ralph of
Kevin and Kell, and Bruno and Fiona of
Bruno the Bandit attempting to play the roles of
Sluggy Freelance characters and find the original cast. Other characters, such as Gav from
Nukees, and Trudy from
General Protection Fault, made appearances. The non-comic characters from
Mystery Science Theater 3000 also appear, in their silhouetted form.
References to Sluggy Freelance in other media Science fiction author
John Ringo has included references to
Sluggy Freelance in his novels. For example, in his
Legacy of the Aldenata series, the crew of a massive mobile artillery platform in the third book are depicted as Sluggy fanatics to comedic effect (including naming their vehicle after Bun-Bun and painting a giant picture of Bun-Bun on it). In the fourth book, ''Hell's Faire
, a character is based on a friend of Pete Abrams who was the inspiration for Riff. A section of original Sluggy comics set in the alternate future world of the novels appears in the end of Hell's Faire'', and a sampler of Sluggy storylines is included on the
CD-ROM bound into this book. Pete possibly returned the favor shortly thereafter by entitling one subchapter "Hell's Unfair." Another possible Sluggy reference is in the short story "Lets Go to Prague" where one character uses the codeword Kizke. This is the common mispronunciation of the demon K'z'k. (The proper pronunciation has no vowels.) Also, the first two novels of Ringo's distant-future
Council Wars series have appearances by an irascible, treacherous, switchblade-toting, telemarketer-hating AI in a rabbit-shaped body, created by a long-dead fan of an unnamed 20th-century webcomic. In
S.M. Stirling's
Conquistador, one of the characters unleashes a self-destruct sequence with the code phrase "Override B-1 oasis". Override B-1 is a program that causes the
Sluggy character Oasis to unleash her own level of destruction.
