Crescent Grizzly

Grizzly Slash (real name: Crescent Grizzly) was a weapons dealer before the virus infected him to turn him Maverick. He dwells in his secret Weapons Facility, and has the Crystal Ball for the laser. He sends out crescent attacks and can also dig. Some walkthroughs recommend defeating him first. But if you need to fight him with a special weapon, use Spike Ball (if you're X) or Twin Dream (if you're Zero).
