How strong would Guts (Berserk) be in the world of Kenichi?

I know they're completely different worlds, I know that very well.

But seeing certain references to Berserk, an idea came to me: What if Guts (or a character based on him) were in Kenichi's world and for some reason appeared in Ryozanpaku? not necessarily as an enemy.

How strong would he be? Who could he fight? Without the Berserker armor, just his Dragon Slayer and other abilities. The truth is, I've been thinking about several scenarios.

I'd like to know what you think! No hate, please. Lately, people get offended by everything.
