I could accept Raiden to an because he was partly mechanical at that point, but nothing involving Vamp fully explained his superhuman abilities and his complete disregard of physics.
Well actually it was passed off as being
the nanomachines in his blood which I can understand to a degree (the whole point of them is to help humans repair tissue and enhance basic abilities) but, and this goes back to what GZ was saying (but a smaller degree) it really ruined his character.
Here's my beef with Vamp and Raiden; Vamp was supposed to be one of the major villains in MGS2. He had an air of mystery and magic surrounding him; was he really a vampire? Who knows, who cares, he was a menace and pretty dispacable, you shot him in the head it should have been over there. By reintroducing him, they turned him into a 2-bit lackey with superpowers. Running on water, dodging bullets, that can be explained as special monk training or predicting where shots will be fired or something. I can believe that in a science fiction setting.
But Vamp was dancing around and leaping 30 feat in the air and Raiden, get this,
WAS BREAK DANCING TWO GECKOS ATTACHED TO A CORD. Slicing a GECKO's legs and running fast I can believe, but Raiden had the strength to literally pick up 10 tons of robots with his legs and SPIN AROUND ON HIS HANDS yet that same strength didn't completely
obliterate Vamp when he stepped on the guy's chest??? Raiden was even pulling off Dead or Alive moves with his SWORD-IN-BOOT spinning around and quadruple sword spinning somersaults.
Those two characters are the only ones that drew me out of the story and left an awful taste in my mouth. Vamp and Raiden have the combined power to kill Ocelot in a heartbeat but they spend it in a cheesy fight that was basically a spit in the face to the series' events. I'm pretty sure there were people MASTURBATING to the scene because, in all honesty, it was very well done fight scene but it had absolutely no place in the game. Any writer worth his salt will tell you that if a scene doesn't advance the story or connect to the theme, it should be cut but this scene was clearly masturbatory and quite possibly the hugest fanservice I've ever seen in a video game. Period.
So everything else I can easily understand being in a fictional universe. Frank Jagger and Olga as the robot Ninja is believable. Nanomachines healing wounds and causing you to go insane is believable. Mechanical suits that enhance human abilities is believable. A guy breakdancing robots and a dude that heals instaneously belongs in Naruto or something. Once again, fanservice, but thankfully it just one scene and the game moves ahead quickly.
