Lean, mean fighting machines can classify some of the bosses in Chrono Trigger, but all of them can be classified as tough.  HP counts are approximated because Lucca's Sightscope can't read bosses.  Besides a picture of the boss and recommended team to face it, you can find out its location, time period, HP, Main attacks, Major Weaknesses, and a mini guide for handling the boss.
Boss Name: Zombor
Recommended Team: Crono, Lucca, and Marle
Time Period/Location: 600 AD/Zenan Bridge
Hit Points: Torso- 960 , Legs- 800
EXP/Tech Points/Gold: 350/10/1500
Main Attacks: Earthquake, HP Drain
Major Weaknesses: Torso- Ice Magic, Legs- Fire and Lightning Magic
Mini Guide: Zombor doesn't have the HP of Heckran, but the Skeleton can give you problems in case you haven't healed after beating the individual skeletons earlier.  Eliminate the Legs first with Fire and Lightning Magic.  It sometimes will Drain your HP, so make sure Marle is healing the party.  After the Legs fall, hit the Torso with Ice Magic and regular attacks.  The Torso's final attack will be an MP Buster, so make sure you stay at an inn on the other side of the bridge after breaking Zombor's bones.
