That is too much size to overcome.
Yep, I think mplatt got it right. A 215-pound male against any 110-pound female is going to be a rout in the male's favor unless the female is either 1) incredibly aggressive, highly trained and skilled at hitting disabling targets in sequence, and following through while under the adrenal stress of a real fight or 2) incredibly lucky and hits a couple of those targets by sheer chance, then has the presence of mind to finish it off before the opponent can recover (or pull a weapon).
That's not to say there are no 110-pound females who fit category 1, because there are (almost all come from extensive training in one of the Special Forces systems, not from any Asian martial arts). And case 2 is always a possibility, made somewhat more likely if the female in question is a martial arts expert and knows about those targets. But most people who do a martial art - even for 20 years - don't fit that first category. They expect techniques and scenario-based training to work for them. Fighting techniques don't make the fighter and don't win fights. It's an offensive mindset, total aggression, hitting first, using the adrenal response to invest more power in your attack rather than having it shut you down, fighting in a subconsious state, hitting targets which will produce a desired and hopefully incapacitating effect, and following through until the hostility is stopped ... that's what wins fights. And if you're way smaller than your attacker, you have to be extra adept at all those things, because you can't afford to screw up and give that other guy a chance. A completely untrained streetfighter is usually better at most of this than over 90% of people who learn martial arts and therefore has a big advantage in a real fight! In fact, most martial artists learn only the next-to-last concept in that list - if they learn that one. And that's an important one to learn if you want to get the upper hand on the streetfighter, but if you don't learn and apply the other concepts, you're taken out of the fight before you can ever hit the streetfighter anyway.
So if you're going to fight somebody - even if you know they are a martial arts expert and possibly a very skilled sport fighter - you must attack and dominate, never giving them a chance to fight at all. Make them go defensive in fear, because that will not stop your aggression. If you outweigh somebody by over 100 pounds and you take it to them from the start, their only chances are those two that I gave above, even if they're highly skilled in a martial art. Believe me, a 215-pound man charging with murder in his eyes and projecting that he will not give up until he's stomped his opponent's head into raspberry jam is going to terrify a 110-pound woman who has never had to face that kind of real attack! If you have to fight, use that to your advantage and don't think about what might happen!
Another word about grappling - good grapplers who can also punch and kick adequately are almost always the best one-on-one fighters. MMA competitions have shown that. So tackling, wrapping up and throwing down works in real fights and can beat or at least neutralize superior punching and kicking skills. Therefore, if you have a huge size advantage, even if you don't know how to fight, just attacking without warning and taking your opponent to the ground and pounding him before he can fight back will often be all you'll need. That's all you should do, in fact, because you don't have any "skills." This works especially well if the "him" is a "her" who's only 110 pounds. But remember - in the street, if you have to face more than one person or if anyone has weapons, staying on the ground longer than about 1.5 seconds instantly becomes the worst thing you can do. So if you're one of those BJJ guys or wrestlers and you can totally outclass a guy one-on-one, knock your man out ASAP and get off the ground. You don't know if his buddies will appear from behind a building with crowbars and you don't want to be caught showing off how effective your arm bar is when they do.
So yes, size does matter. If it's 215 pounds vs. 110 pounds, just charge in there and dominate. The smaller person would have to be nearly world class or just stupidly lucky to have a chance.
