Is that how it works? I volunteer as midboss!

Final boss is Vin Diesel. You can't beat him without becoming the final boss yourself, but he puts you in a headlock and argues that you're valid until you accept that the highest expression of masculinity is acceptance of all facets of oneself. Afterwards you share a bro hug and he DMs a session of D&D for you along with all the men you defeated along the way as your adventuring party
