I've got a burning question in my mind about Koizumi (oh yes he is mysterious). In the animation of Sigh IV,

Spoiler for Sigh IV Koizumi:

Kyon gets so mad at Haruhi that he raises his fist to hit her (righteousness 1, chivalry 0). Koizumi then rushes forward to grab his wrist, thus preventing him from punching Haruhi. My question is this; how on Earth can he move so darn fast? He was on the left of Kyon, tending to a drunk Mikuru, then in an instant was standing on the right of Kyon, and grabbing his wrist. Does he actually has more power than he lets on? Athleticism is one thing, but superhuman power is another. He's strong enough to hold back Kyon with one hand nonchalantly when Kyon's using his full force to try and sock Haruhi, and he's fast enough to see Kyon raising his fist, and subsequently determine to run to Kyon's side and grab his wrist while it's moving in the air.

This just seems to me that other than his Closed Space powers, he has enhanced intellect, speed, senses and strength. Then again, probably Kyon is just weak.
