Who would win in a battle between the team of Batman/Bruce Wayne and Robin/Tim Drake vs. Ryu and Sagat?

Ok. There are two key things we'd need to be clear on before we can adjudicate this fight. 1. How powerful are Ryu and Sagat?, and 2. What's the most powerful opponent that Batman can beat? Neither of these are questions that can be answered easily.

First, how powerful are Ryu and Sagat, really? It's quite hard to say. The actual games can give you an idea of their power in relation to other characters from the same games, but what does that mean in the real world? How quickly can they move? How much damage does one of their punches do? Their fireballs? Who knows? The best one can do is try to work out their abilities from one of the animated adaptations, but their have been several, and their powers have varied wildly in each.

As I recall, Capcom has went on record as saying that the way their abilities were portrayed in the animated version of Street Fighter Alpha was close to their "real" power, so that gives us something to work with; but not much. Some fans point out the scene where Ryu dodges handgun fire in that movie, and compare his speed to Raditz from Dragonball Z, extrapolating that Akuma would be as powerful as Vegeta, from the same. Others interpret the same scene as Ryu moving to either side a split second before the gun was actually fired; this would require far less speed, putting Ryu on a roughly equivalent tier with Spiderman from Marvel Comics. Personally, I like this model better; it makes the Marvel vs. Capcom series make a lot more sense. So, let's say Ryu is roughly as powerful as Spiderman or Wolverine, okay?

That brings us to the next hard to answer question: How powerful of an opponent can Batman actually beat? This is far harder to answer. It is true that the canon contains incidents of Batman beating vastly powerful beings like Superman and the Martian Manhunter. However, there were always, always, mitigating factors. DC comics has a habit of giving it's heroes powers that verge on omnipotence, with a single crippling weakness that renders them helpless. Far Superman, it's kryptonite; for the Martian Manhunter, it's fire. Fans point to examples of Batman beating Superman, conveniently ignoring the fact that with kryptonite, anyone can beat Superman. And even when Batman fights opponents that don't fall down when you wave green rocks at them, he often wins due entirely to "plot induced stupidity"; the plot of the story called for Batman to win, so he won due to some kind of completely ridiculous Deus Ex Machina that the writer pulled from his *** at the eleventh hour. The Tower of Babel story arc is the best example of this I can find; it involved Rhas Al Ghoul defeating the entire Justice League using methods Batman planned; without getting into the specifics, it was the most retarded story I've ever read in a comic book, and the only reason that any of the strategies worked was that the writer said they did.

These two factors have led to what I call the "Time To Plan" fallacy: the belief that Batman can beat any opponent (Alexander Anderson, Spiderman, Dante Sparda, Motoko Kusanagi, God) if given enough time to plan for the battle, determine their weaknesses, and exploit them. There are two problems with this idea, though. The first is that it gives Batman an inherit advantage, in assuming that he's provided with all the relevant information about his opponent's abilities, and infinite time to plan his tactics. One wonders: "If Batman's being given knowledge of Spiderman's powers and a week to plan the fight, shouldn't Spiderman be given Batman's secret identity and the location of Wayne Manor? And shouldn't he be able to show up at Wayne Manor and kick Batman's *** before he get's done mixing up his "anti web spray?" The second problem with the "Time to Plan" fallacy is, whenever a proponent declares that Batman could beat an opponent without a single glaring weakness, they never have a valid plan for how Batman could do it. They simply assume that Batman will magically come up with a tactic that will overcome all of his opponent's powers, even if there's no logical way for it to happen. Which is exactly how it would happen in a Batman comic, by the way.

So… back to the original question. Could Batman and Robin beat Ryu and Sagat? If we base our idea of Ryu and Sagat’s power on the Street Fighter Alpha anime OVA and look at the way they fight in the games, we can get a pretty good idea of the threat they present. We can tell that both are extremely strong and agile, probably more so than any human could be in the real world; they’re able to strike an adult male hard enough to send them flying back several yards, and making standing vertical jumps of heights that exceed their own body lengths. We can also tell that they’re extremely durable, capable of being struck in the heads by full-force punches and kicks from people of strength equal to theirs a dozen times or more before being knocked unconscious. We can tell that they’re highly trained martial artists with excellent reflexes, no doubt with impressive athletic capabilities all around. Hard to say how much damage their fireballs will do, but we can guess it’s somewhere between the damage inflicted by a shotgun blast and that inflicted by a grenade exploding. More importantly, it’s something normal people can’t do, and would be a surprise to Batman and Robin when they first use them. Based on all this, my opinion is that Ryu and Sagat would have a clear advantage, and, sensibly, should win the fight.

If, however, the fight took place in a Batman comic book, or the mind of a fanboy, Batman and Robin would still win. The fight would have to take place in Gotham City, where Batman would have access to the Batcave, and he’d have to have advance notice of Ryu and Sagat’s fighting abilities; say, they’ve arrived in Gotham, they’ve been competing in an underground street fighting tournament, and Batman has video of them fighting and beating up people like Bane and Atomic Skull. Based on this, Batman would develop an “anti-ki” spray to render them incapable of throwing fireballs, and then he and Robin would just get in the Batmobile and run Ryu and Sagat over.

So to conclude: I agree with you that Ryu and Sagat should win. But you will never, ever convince a Batman fanboy of this.

Batman has "won" in stand-up fights against some of the most powerful characters in the DC universe - including Superman. Generally speaking, if he has time to prepare (not even counting how crazy-prepared he is normally), I don't think anyone has much hope to beat him. He's at olympic fitness levels, essentially unlimited material resources, comprehensive training and vast experience in fighting, a surly disposition...

In a video game? Dunno.

Batman was able to fight against scorpion and sub-zero in mortal kombat Vs. dc and
