Frankly, the limits of his powers have never been made clear enough for my liking. Could he acquire the flexibility of a contortionist just by watching one? To what extent is exercise necessary for him?
My geek opinion-he needs to exercise for things like physical strength, stamina and flexibility. He can copy the punching technique of any boxer. But if he wants to throw a punch with any force, he’s got to work out like the rest of us and build up some muscle mass.
Re-His Ranking
It is clear that the TaskMaster can not copy any action or ability requiring superhuman or mystical capabilities. He could perfectly copy the intricate gestures and postures of Dr Strange, but without Strange’s occult power TM couldn’t reproduce the magical effects.
From the Task Master Series TM watches lots of action movies. He is the equal of Chan, Li, or even Bruce himself. But, while plannning a particularly difficult job, TM realizes something. If he watches the films at high speed, he can perform the moves at high speed. TM has a normal human body, however. He can only move at high speed for brief periods before he begins to seriously damage his body and especially his heart.
Thus, the Task Master could not copy the chi abilities of Iron Fist.
Other than that, I’d put TM in the #1 spot. If he can watch Shang Chai, Elektra, or any of the others, he has the same moves they do. More, he can copy the action instantly after watching it. TM learns any move an opponent uses. If one of the other martial artists is better than he is, he just has to hold out. After a few rounds, he’ll be just as good as they are.
Non Spoiler-One of the things I liked in the series was that TM studied not just a person’s individual moves, but their entire strategy. AFAIK TaskMaster is the only villian to realize that Spidey routinely outfights opponents much more powerful by getting them angry and off balance. So TM does the same thing when faced with similiar odds.
TM won't simply copy Elektra's kicks or punches. He can copy the combinations she uses them in and her entire fighting style.
Sam Hell, unless the person you'd rank as the top martial artist in the Marvel universe fights with mystic or superhuman abilities Task Master only has to watch enough film of that person to be every bit as good.
