Strong-Klez is one of the boss viruses in the game BOTS!!. It is only found in the Training-Ring sector. It is supposedly another training boss virus, commanding squad after squad of Klez and similiar relatives. Its design is exactly the same as a Cruncher's, having Surge technology and Spiker transformation similarities. Its attack style, however, is completely different from the Cruncher's. It will usually attack an opponent with a jump attack or a quick blow, and then move away quickly, then come back to attack again. It takes some strategy for a novice player to defeat, but still simple for an experienced player.
