Yup, the analogy was cute. However he did have some very salient points.Furthermore, while the Sentry can fly very fast, and has a host of powers, his fight against WWH was basically quite 'interesting.' For the most part they were just trading blows.
Ask yourself this ....if you were the Sentry, and you were fighting WWH, would you fight the way Sentry did?
Most people (if they are honest) would not. Why? Because it would be stupid.
In a KMC fight any multi or omni dimensional character (e.g. Gladiator, Superman, Silver Surfer, FireStorm, Sentry, etc) will not go and trade punches with a uni-dimensional character (e.g. Hulk, Juggernaut, A-Bomb) .....and this is not PRIMARILY because they might lose (although there are risk factors involved), but primarily because it is STUPID.
It would be like me having a stapler, and you having a handgun (with bullets, and you being a great shot) .....and instead of shooting me you decide to come in close and try to pistol whip me.
Even if you might win, it would still be dumber than a frog steaming up in a hot kettle!
A writer can show the Flash being defeated by Gorilla Grodd (I am sure that has happened even). The Hulk can be written as being defeated by Jubilee. Next month you might see Thanos get handed his @$$ by Kitty Pryde. All of those could happen.
But powerset against powerset, it should not. With all parties concerned going all out it just becomes impossible.
Once again I ask, if YOU were Sentry, and you are facing WWH ....would you fight the way Sentry did? Or might you just (just) decide to use all the other faculties under your control?
Same with the Glad vs Hulk (or Supes vs Hulk).
Imagine you are the Hulk: You know there is Superman/Glad/Sentry around, but he is moving around so fast that you cannot even SEE him. That means one thing (without me having to add more to this).....you CANNOT win. It is not whether or not he can beat you, it is the fact that you cannot beat HIM. You cannot see the character, touch the character, punch the character. People like using the X/10 scale ....well, in this case it is 'You will not win 10/10.'
Whether you lose or not is another debate, but you cannot win.
Imagine you are Sentry/Glad/Superman: You are facing the Hulk, but everything he does is in super slow motion. He tries to punch and you might as well have gone to China and come back in that time frame. You are literally all around him at the same time due to your speed. You can punch the guy a multitude of times in the space it takes for him to throw one punch to you. You can heat him up with heat vision, chill him with ice breath, blur his vision with debris from hurricane force winds. Or you can simply over-saturate him with a multitude of blows from a near 360-degree arc. And in all this if he tries to punch it is as if he is moving in slow motion.
Again, in this case there is no need to debate whether or not you would win. The thing is that it is IMPOSSIBLE for you to lose. The X/10 scale in this case is that '10/10 you will not lose.'
