Now before anyone flips their shit over how Puck isn’t a mutant, know that John Byrne did not necessarily intend that to be the case. The bizarre origin story of the “magical demon inside Puck that makes him strong but also short” is a bit of a retcon. He was definitely intended to be a natural little person but the Byrne plots (the first 30 issues) didn’t quite get around to explaining how he got powers, although I’ve always thought being a mutant is a simple explanation and makes sense.
X-Rated version on my site, anti-heroes.net → members gallery → fan-boy → X-Men RemiX. Puck may be short, but his appendages most certainly are not!
