What if Sym attached to El Toro instead? - Anonymous

Has El toro ever fought crime or wrestled with a musclegut? - Anonymous

I love being able to answer multiple questions at once! Anyway, if Sym had bonded to Jose instead of Keith, Jose would have become the super shiny superhero El Galvo. He could use aircraft carriers as baseball bats! Stop errant doomsday comets by punching them into space dust! Put galactic planet-eating near-gods with funny headresses into submission holds until they tap out and swear never to come back again! And he can use his bicep as his own personal mirror.

Also, shortly after bonding with Jose, Sym would discover the amazing culinary delight that is Mama bravado's cooking. Sym would insist that Jose sample more of her meals than he usually would 'for science', giving Jose a thicker middle. Of course, Jose wouldn't really mind because of aforementioned comet-punching and god-wrestling.
