Alright. I'm back, and I'm gonna settle a few things. This is to everyone who replied recently.
1) Pikachu cannot use TM moves unless he has used them in anime/manga (i.e: He can use Flash, but not Wish.)
2) You two, please stop downplaying Pikachu. The reason that it's so inconsistent is the reason we can rate his durability at town, as we have no other way to do it at his best, which is perfectly even with latios, and tanking both, Dragonair and Dragonite. He's town on this site, so don't argue otherwise. I can't argue star level SPC for that reason. And manga Pikachu has feats against Mewtwo, who in turn has feats against Deoxys, who wrecks Snake in AP, Dura, and Speed. Don't go there with the non canon Solar Gun and such, which won't affect Pikachu with his durability...
3)Double team would be a viable option, and the defence isn't a thing. It was retconned later, with it never being proven since. Even then, it's not like Snake will be capable of telling the difference. Alakazam, which was a good point by the way, was fooled
4) The guy who can shoot lightning out of the air. That just means he has that reaction speed and his weapon is lightning speed. Most weapons won't be capable of deterring Pikachu.
5) Composite Pikachu is the one on this site so ALL MOVES ANY PIKACHU HAS USED OR CAN LEARN W/OUT TMS OR BREEDING CAN BE USED. I had no idea Electric Terrain was a thing, so I didn't argue it prior. Electric Terrain is a viable solution. Besides, Cosplay is PIS. How can changing a costume change one's moves.
6) Snake's basic weapons won't even pierce Pikachu. Just thought about that. This includes the tranq.
7) Pikachu, or any pokemon is capable of using all proven moves on most if not all battle forums. Do not aruge against this, not because I don't want you to, but it is a fruitless effort.
8) Pikachu being capable of buffing his speed would definitely put him above Snake
9) Pikachu doesn't have nanomachines. The dolls won't work. Nice try.
10) Pokemon paralysis (at least from electric types is much more effective than a taser. Why would you even compare them? Plus, Snake's page has nothing on him being resistant to electricity.
11) Blinding him would work long enough for a MHS character to drown him with Surf, omni attack with thunder wave, find and kill him closely with iron tail, etc.
12) Nanomachines can logically be short circuited.
There's more, but I have to re-read through the thread to remember.
