Your highest is not 212. Zamus' B-Up is a terrible strategy. Just stop.
On topic, I believe that you said that the bet was that in a year, you
could have 999 KO's? Then allow me to present a step-by-step itinerary for winning this bet:
1. Mess around for a year. Personally, I prefer
the air to mess around while eating lots of cake. Delicious, delicious cake.
2. Explain to your cousin the
Many Worlds Theory, where literally ****ing EVERYTHING is happening in some version of this world, somewhere. Meaning in some world, your left arm just turned into a snake while reading this sentence. Meaning in a bunch of these worlds, you got 999 kills in Cruel Brawl.
Meaning you
can get 999 kills in Cruel Brawl, it's just luck of the draw which world you're in. Your world, you didn't get 999 kills, but the bet isn't whether or not you
did, it's whether or not you
could. Savvy?
and if that doesn't work...
3. Explain to your cousin the
Quantum Entanglement Theory, where the existence of an object is entirely dependent on a counterpart, which is spatially separate, yet the same object. Since they are the same object, just in two different places on a quantum level, whatever happens to one, happens to the other. (Simplified)
We can continue up our fun little logic tree to deduce that, since your copy of Brawl and the copy of Brawl in the Many Worlds that has 999 kills are actually the same object in two different spatial areas, whatever happens in one, happens to the other. So although you have not actively achieved 999 kills in Cruel Brawl, there are 999 kills ON Cruel Brawl, he just isn't experiencing a high enough level of concsiousness to perceive it. Same idea with you: you and your Many Worlds counterpart are the same object. So you've actually gotten 999 kills already on Cruel Brawl, using Ridley, playing with your feet. But your puny little human mind won't let you experience the realm of eternal possibility.
Then, while his head is spinning trying to understand all the science flying around, poke him in the eyes, kick him in the shins, grab his money and run like hell.
