I found a guy called EnemyBird(a guy who thinks Snake is no better than any character in fiction) saying, Connor would wreck TTS Snake(a superhuman version of Snake) just because he hates Snake and saying that Snake would lose to Daniel and Dre from Karate Kid.
So... I decided to make this fight on this forum.
Round 1: They are hunting each other in Firenze.
Snake only has his SOCOM and Connor has every weapon from the game.
They starts against each other from 1km.
Round 2: Snake is unarmed and Connor has a Tomahawk.
Final Round: Pure H2H.
Round 2 and the final takes place inside of a Roman Colosseum.
I've seen Enemybird on Comicvine, nice guy but a bit a ridiculous sometimes
Snake would win here without too much trouble, Twin Snake's Snake was consistently pulling off showings above Connor's level.
He wins round 2 and 3, Round 1 I usually give the AC characters because of Eagle Vision but considering this version of Snake dodged the PSG1 that his normal counter part was unable to, Connor can't tag him with any of his weapons even if he does get the drop on him. Snake wins the first round as well.
