Basically out of all the monsters in the series which would you find the toughest to beat. I would say the Last Buddha monster with all the arms. It had tons of weapons; lazers, healing powers, swords, acid/something that burns. It killed many people and no monster even compared. In second I'd say the last Dinosaur. It was fast and stuff but it could have easily been beaten. I was dissapointed in Kurono with the Shorty Alien, he killed all but one because he was too sissy to blast it's ass. And then it goes back and kills all his friends (which he denied them as his friends until they passed).
