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: Nizbel
Recommended Team: Crono, Ayla, and Robo
Time Period/Location:
65,000,000 BC/Reptite Lair
Hit Points:
4200
EXP/Tech Points/Gold:
500/10/0
Main Attacks
: Release Electrocution, Nizbel Charge
Major Weaknesses:
Lightning
Mini Guide
: Nizbel is a very tough opponent unless Crono has Lightning Magic ready to go.  Because Lightning will lower Nizbel's Defense (as well as killing most dinosuars), powerful physical attacks are needed so Robo should accompany Ayla and Crono.  Nizbel will occasionally release the Electrocution stored in himself, which means you will need to quickly have Robo cast Heal Beam on the party.  Nizbel will fall relatively easily as long as you follow Lightning with Physical Attacks.
