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 II
Recommended Team: Crono, Ayla, and Robo
Time Period/Location:
65,000,000 BC/Tyrano Lair
Hit Points:
7000
EXP/Tech Points/Gold:
880/15/0
Main Attacks
: Release Electrocution, Nizbel Charge, Increase Defense
Major Weaknesses:
Lightning
Mini Guide
: Nizbel II is much tougher than the original Nizbel and not just because he has more HP.  Nizbel II can be weakened by Lightning and it will still lower his Defense, but now your physical attacks will raise his defense back up.  He doesn't really have any new attacks, but all of his attacks are more powerful.  Robo is recommended again because of his Heal Beam, but if you are more comfortable with Marle, go ahead with her.  Do 7000 Damage to this second generation baddie to send him, er, keep him in the stone age.
