The Karate KidEdit

The Science Police assigned Hart Druiter to a special unit that was dedicated to capturing Grimbor.

When most of the Legion ended up hit by a weapon that removed their powers, only Karate Kid was left to fight him. Karate Kid managed to defeat him when one of Grimbor's chains got caught in a shaft and Grimbor was seemingly destroyed when Karate Kid triggered an explosive device on his belt.
