@SMXLR8: This have to do with the meteor-cutting feat?
I'd say wait and see what else the shikai can do before jumping the gun on assumptions. Kenny could equal Berserker in raw strength with that feat, but God Hand's still an issue.
@othus12: There was never an upper limit shown to his strength within the series. Of what is shown, the pressure of just a casual swing he exerts from his sword can level several buildings around him all at once and he was capable of deflecting a weak Excaliblast from Saber with raw strength. The Servants within the Holy Grail War could be easily killed in one hit if he inflicted a direct hit on them, which includes even those as strong as Saber whose armor is city-level durability at its maximum output of power. Even if one is successful at blocking Berserker's blows, the raw power exerted from them is enough to drive back his foes dozens of feet away.
Also considering Berserker is Hercules, it's possible to assume that he retains whatever physical capabilities he had during his time alive in the myths. During one of his Twelve Labors, Hercules was shown to hold up the world while he was awaiting Atlas to give him the apples of the Hesperides.
