I've been thinking of the "Can Granny Weatherwax beat Bugs Bunny" question and this is my full take for Discworld characters:
Vimes - Cares too much, too easy to piss off. Has the innate chase instinct that makes characters run into walls with realistic tunnels painted on them. Might get to arrest Bugs Bunny but the beast will just slip out of the handcuffs to help him lock them, then walk out of the jail cell to have a union mandated coffee break.
Ridcully - Classic hunting season scenario, but has enough charisma to probably still get a few good shots off before the inevitable.
Rest of the wizards - No survivors, only Bugs.
Carrot - The intense near-magical narrative aura of well meaning innocence should make him immune, Bugs will likely be forced to be the villain of the episode.
Lord Vetinari - Flattened by a comically large anvil in the first few minutes of the episode, unclear if it was all a part of his long term strategy or not.
Moist - Has the 'lovable trickster getting away with it' energy, but nowhere near Bugs level. Already fell for the "old lady who swallowed a fly" scenario with the stamp slugs once, won't fare any better here.
Death - Definitely one of those "character is trying to avoid death" episodes, would go back and forth. Might actually get to end Bugs but his spirit will reappear in Death's domain and ruin his garden.
Nanny Ogg - The ultimate in anti-Bugs technology, a gleefully annoying old lady who doesn't give a fuck and definitely won't be the first to instigate the plot bearing conflict. This is a full sweep, he's the episode antagonist.
Granny Weatherwax - Too win-motivated to not lose. Would have to break the story to have any chance. Might do it.
Magrat - Will have sappy ideas about helping the poor animal which honestly has the 50:50 chance of either getting slapsticked or Bugs ending in a ye olde stroller&pacifier gag.
Colon&Nobby - Designed in a lab to be totaled by Bugs Bunny.
Tiffany Aching - A child that also has a large pan that is the perfect thing to hit someone over the head with and make a BOIOIOINGGG sound, so great odds.
The thing about Granny Weatherwax is that she understands the plot structure of the story she's in. And with Bugs Bunny, understanding the plot structure is the key to victory. She just has to bait him into making the first move against her, turning him into the antagonist. I think I already said this on another similar post, but if Granny bakes a pie and puts it on the windowsill, it's all over for Bugs.
