The Strange
Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch! ~Through the Looking-Glass by Lewis Carroll
Overhearing the burbling jabber of three quarrelsome siblings is unpleasant at best. At worst, it could portend the imminent appearance of the jabberwock. Given how disagreeable such a meeting would likely be, one's best option in that situation is to run.
Due to the creature's frumious manner, no one alive can claim to be an expert on its habits, demeanor, and nature. That doesn't stop people from trying to figure out why the three heads—one named Jabberwock (for which the whole creature is known), one named Jubjub, and the last named Bandersnatch—are always so angry with each other. At least one thing's clear: if someone wanted to slay the beast by cutting off its head, the task would require three decapitations, not one.
Motive: Unknown
Environment (Wonderland | Magic): In the wabe
Health 32
Damage Inflicted: Moderate wound (7 points)
Armor: 4, 15 against fire
Movement: Short; long while flying
Modifications: Speed defense as level 5 due to size.
Combat: Each of the jabberwock's three heads can attack a different target with a bite within a single action. Alternatively, the jabberwock can spend its action to make two claw attacks, and either deal damage or catch the prey in its grip. On subsequent rounds, the jabberwock automatically bites prey caught in its front claws (leaving one or two heads free to bite other foes that are not yet caught). The only physical action a human-sized victim caught in a jabberwock's claw can take is to attempt a Might-based or Speed-based roll to escape the creature's clutches.
Once every other round, the jabberwock can breathe heat (or cold), inflicting damage on up to ten targets within short range of each other and within long range of the jabberwock. Even on a successful Speed defense roll, targets still take 1 point of fire (or cold) damage.
Interaction: A jabberwock usually puts aside the quarrels among its heads to eat prey, but crafty interaction could turn the jabberwock on itself, at least for a time.
Use: The jabberwock's lair contains a trove of amazing items, and perhaps the PCs need one in particular.
Loot: 1d100 x 10 gold coins, 1d6+3 cyphers, possibly a Wonderland artifact.
GM Intrusion: When the PC hits the jabberwock, it roars with newfound rage! The rage provides it with renewed vigor (and restores 15 points of health to the jabberwock).
And as in uffish thought he stood, The Jabberwock, with eyes of flame, Came whiffling through the tulgey wood, And burbled as it came! ~Through the Looking Glass by Lewis Carroll
