Black Hole Mobster Kingpin

Black Hole Mobster Kingpin is the resulting form of Mobster Kingpin after tightening his Gravity Bustier to such a degree that his mass increased several orders of magnitude, and his volume reduced sufficiently to allow him to fall entirely within his own Schwarzchild radius. Thanks to The Laws of Physics, in this form he appears to have become entirely invulnerable, as his mass has become too great to move by conventional means, and any attacks would simply be swallowed into his event horizon.

Taking his mass as roughly equal to Earth's, his event horizon is roughly the size of a peanut, putting into perspective the scale of the Game of Life.

Ironically, the very Laws of Physics which protect him in this form may also offer a possible weakness for this form of Mobster Kingpin. The equation defining the size of the Schwarzchild radius is

$$r_s = \frac{2Gm}{c^2}$$

relying on the speed of light c. If the speed of light were to be increased, perhaps via some weird puzzle shit to get the electric current to the giant fan faster, Black Hole Mobster Kingpin would be once again vulnerable for a time, since he would no longer fall under his (now much smaller) Schwarzchild radius.
