Dennis

NAME'S DENNIS! I'VE BEEN HIRED TO EXTERMINATE YOU.

the dennis

dennis is a sadistic, homicidal and ruthless bounty hunter five times as dangerous as Nack the shitter who was first seen being hired by Zigra to stop the Science Special Search Party and Hero from interfering with the construction of the Troll star, he is the secondary antagonist of the troll star arc

He managed to succeed in defeating hero and the SSSP in a matter of seconds but was later defeated after the troll star was destroyed

The only people he truly fears is Rick, Kine and Coo because they kicked his ass and tore open a new one on his 6 pack.
