Height : 12"
Weight : 102
This is loving phenomenal. Assuming normal human width and depth, with this height and weight, this thing would literally have to be made of gallium.
Assuming normal human proportions (1/6th width and 1/6th depth as well as height), there is no metal in existence that gives a density ratio of 216:1 to normal human density.
In other words, this character is impossibly dense.
