No, it does not take them into account, it is a straight arm punch in the absence of other factors, like Drag, absorption of force due to Fat Resistance Force. How much do Brass Knuckles Weigh, I can't find that anywhere. Air-Drag + Fat Resistance Force will slow down Olimar fist, even if slightly.
Plus, Olimar has no true formal combat training whatsoever, so he wouldn't be likely to think to aim for the nose or forehead. Besides, punching on IC leaves him open to attack from the other, which is the biggest weakness in your scenario where he runs up and punches one.
The fact that there are two of them and that they are a team enables them to be more situationally aware than a single fighter alone, if the other spots Olimar coming in, he/she will alert the other of the impending threat, allowing them to react or they could end up noticing Olimar themselves and react upon that. The Buddy System works wonders in a fight.
Also, we gave Mario a plunger at one point, did we not? That is an example of something the character is shown to not have on their person canonically speaking. Therefore the ICs
can have climbing equipment, which would be
required to scale mountains of any kind anyhow. Besides, even real life ice climbers have equipment suited for their craft, which is required in order to do it.
The Ice Climbers can and
must have climber equipment. Period.
Also REL, you apparently cannot read between the lines of what I was getting at with the Sumo, so I will spell it out for you.
I was using the Sumo as an example of an obese person having toned, developed muscle, the kid I showed earlier whom had all those developed muscles is an example of a kid with good muscle tone or bulk. That therefore mean that the ICs
can have that toned muscle from what they do. Ergo, the Ice Climbers
can be physically strong as well as fat. Their hammers make them even more dangerous with this.
Rest is assumed, so the idea that they can be physically strong as would be required is plausible. No ifs, ands, or buts.
EDIT: Wanted to tell you what you are saying the ICs are in height.
A Growth Chart for Boys two to twenty years of age in regard to the ICs. If Popo is 5-7 years of age and Nana is the same size as he is, you are placing them at around 3.8 to 4.3 feet tall. Their average height between the two (age 6 or so) is 4.05 or four feet. You cannot prove whether they are 5, 6, or 7 years of age specificly. So you cannot determine their true height.

That means that the length of their arms in relation to their body are anywhere from 1.8 to 2 feet in length. Their average arm length is 1.9. In other words, at 6 years of age, they are at equal height and arm length as Olimar, the reach their hammers have gives them an advantage over Olimar in reach.
They can out reach Olimar, and because of this, once Olimar comes in for a punch, the IC he is attacking, if they notice him beforehand, can catch him in the head as soon as he is in range. Once he is knocked over, he is vulnerable to a whack to the stomach or groin area, as well as his helmet.
The Pikmin won't be able to help much since at least a couple to a few of them could be killed within that time frame. Making them less of an imposing threat that you, REL, make them out to be.
The Pikmen's height are now assumed to be anywhere from 2.5 to 3 feet in height. Their arm length of 1.2 to 1.4 feet in length. Too tall to reach the faces of the Climbers. This means that the Force they exert is around this
F = M*A, therefore F = 0.4 * 0.9, 1.0 or 1.1 m/s = 0.36, 0.40 or 0.44 N
N -> Lbs F = 0.1 lbs.
In other words, the Pikmen are no threat at all to the Ice Climbers due to lacking necessary force, even if they swung, the Pikmen would be too weak to do much of anything. This means they are an arbitrary factor and are fodder for the ICs.
