Hehe. That is funny; didn't know Snake was ranked. Actually, I guess I did see the RPGP once - I remember Snake vs. Terra, which I assumed was at GameFAQs or something. One of the rare matches where Snake clearly loses even given concealment, thanks to Merton/Ultima hype. (Snake vs. Celes? Celes Vanishes... Snake puts on Thermal Goggles and snipes her out anyway.) I see some familiar commenters poo-poohing Snake in the comments... (though DarkHolyElf apparently hypes Jet as having an instant death attack? Maybe he was referring to someone else...)
Rozalia: Snake HP hype?! Since we're already in the realm of "it makes sense to me," Snake is either average HP (take cast averages seriously) or pathetic OHKO bait (semi-realistic character vs. wholly unrealistic characters). Of course, Snake's HP doesn't matter that much, as his dueling worth ENTIRELY depends on whether you see the arena as a mostly empty dueling ground, or some kind of messy facility or jungle with plenty of places to hide.
I will say that as far as not-really-RPG characters who might be fun in Not Ranked... Super Metroid's Samus. She's got a smidge more than average PC HP (PCHP + Reserve Tanks), and arguably her power suit gives her ridiculous defense that quarters most incoming damage (not if you average defense too, but Samus does feel very "tanky" in game). She's got a beam attack that is arguably ITD (wave goes through walls? Though the ITD would be factored into damage averages and actually be a liability against low-defense people) and optionally ice elemental, and can be charged. She also has a Xorn-like Death Knell lite game by dropping Super Bombs to set up big damage two turns or so later (followed by a bevy of Super Missiles or Charged Shots). Plus, she gets one shot of full healing from the super-bomb healing trick if she doesn't already have a super bomb out. Probably Low Godlike; not a fast blitzer and status bait, but a good tank.
