Alright, let's try to do this properly then (I am a fnaf fan, and lack knowledge about Dexter outside his profile, so feel free to correct me if I am wrong on anything regarding him since I am purely basing it on the profile.
- Dexter is too weak to damage Michael.
- Dexter has a faster overall speed than Michael, but Michael has an extreme speed advantage in attack speed with Tazar
- Dexter has the Striking strength and AP advantage (Duh, Micheal is a skinsuit)
So Neither should be capable of Physical harming the other (So basically a tie), now let's get into hax
* Michael has a row of Semi useful hax that can flip the advantage into his favour, mainly his stealth, RE, and the immortalities gained from Remnant.
(Note Remannt is weak to fire)
* Dexter seems to have all his hax from mental gymnastics (his IQ), and is extremely good in combat with or without weapons, but nothing completely unrealistic.
So Michael has the advantage in hax, Now let's get into intelligence.
* It's not even funny how outclassed Micheall is in this category...
yeah, Dexter takes this category without a doubt.
So yeah, I think this match will be decided solely by Dexter's first actions, If he goes into close combat or not. If he does he will most likely get Speed blitzed eventually since he would be unable to cause any real or permanent damage to him, so it's only a matter of time before he gets hit by a Tazar and its GG. If he decides to do something else, he still needs to be careful when engaging, due to the reasons mentioned already but would love it if a more knowledgeable member could write a likely scenario here.
So does Dexter have any real wincons for this fight? yeah, By SBA, he can win by either incapping his opponent or killing him, and should be possible since I fail to see how Dexter would not be able to cause a fire in a fnaf location...
Now, what are Michael's winconditions? Simple, he wins if he can hit Dexter with a Tazar ones, then it's GG.
So yeah, both have wincons, but Michael has a better chance of achieving his, but depending on Dexter's actions, it can also be likely to be an incon.
So yeah I am for now voting incon, but leaning towards Michael win.
