This was an interesting idea for a story. Two monsters against each other...thumbs up!

Just got into Monster recently, and this is certainly a fascinating idea.

I'd probably be putting my money on Johan to win such a fight, though. Aside from what you've mentioned, Light also has a well-established tendency to strike back against challenges, rather than pull back and use discretion. Exactly the kind of thing that Johan is capable of exploiting.

Still, could go either way, right?

Excellent as always, DB - and I agree, Johan would probably win since he's nowhere near as erratic as Light.

Creepy!

A crossover with Death Note and Monster? Is it my birthday already?

Keep going, this is amazing.
