Alright, so... It's been a while since I've cared about this wiki, and I think that goes for most people. However, I have decided to write a blog containing links to my favorite fan stories, characters, organizations, etc. This should help with keeping better track of the best stuff for future reference, without having to sift through endless rubbish to find it.
For starters, the once uber-popular T.U.F.F. Company is definitely worthy of a mention. Although this series could be a little disjointed and all over the place, it was a labor of love for many people (especially User:KittyKatswell925), and numerous cool characters were created for the series.
Some of my favorites include: Crazy, Claire Catty200, Skipper, Agent 19, Kat, and Ralph Wolf. All characters can be found here: T.U.F.F. Company/Appearances. There was also a notable villain created for the series, Dark Viper. The Red Knight was another antagonist.
As for stories, Good-bye Company, Uncomfy Company, and A T.U.F.F. situation top the list. For a complete list, see the main article.
There was also a T.U.F.F. Company Comic. Well-worth checking out.
Another series that captured the attention (and hearts) of many people was the Kudley series by User:PoofFan93. Her lighthearted and charming stories were centered around the family lives of Dudley Puppy and Kitty Katswell, and their children. Fan favorites Mandy and Tiffany Puppy were among the six Puppy kids featured in the series.
Numerous other characters were tethered to the Kudley series as well, including the Catson sisters (Cream, Flame, and Tortie), who were friends of Kyle Puppy. Mandy and Tiffany's eventual spouses, Alexander and Mutt, are also worth mentioning.
Other individuals ventured into the Kudley realm as well. User:Anti-Cosmo Dude (who also created T.U.F.F. Puppies), had his own Kudley series. Klyde, Katy, and DeeDee Puppy were created by User:Dabutlers100, as was Jacqueline Rabbit.
I really enjoyed some of User:TurboDudley's fanfics, including Stay T.U.F.F!, Olympic Mutt, Heart of Steel, and Lab Rat. TD created some cool fan characters too, including the popular Ferenc Kiss Alsatian and Mary Vixen. Others worth mentioning are King Komodo, Mattermen, Rudolf Doberman, Joseph Wagner, and Sasha Katzlov.
Prolific T.U.F.F. Company fanfiction writer User:Crazypuppy penned Jack's Return, an 11-part series delving more deeply into the relationship of Jack Rabbit and Kitty. T.U.F.F. vs. Sponge was an entertaining crossover of TP and SpongeBob SquarePants, written by User:KittyKatswell925. The T.U.F.F. Puppy Movie by User:Jonnycade7 was also rather intriguing.
I wrote a biography of Kitty Katswell that was very well-received back in the day. I also did several fanfics, including The Final Stand and To Russia With Love.
Other fan characters worth mentioning include: Samuel "Ghost Eye" Mitchell, Captain Henry Jones, Carter Carbon, Tabby Burke, Chris Welch, Bekidding (T.U.F.F. agent), Herbert P. Bear, Private Starson Vietnam, Nathan Foxer, Roxanne "Red" Pawdale and Tony Waxor.
