We are all familiar with The Hulk and his ever increasing strength, but where does this power ultimately come from?  Is it somehow tied to his psyche?  Is there an altered biological reason for this transformation?  In this episode we take a look into mind of Dr. Banner to see if it holds the key to The Hulk.  We also compare this duo to the most famous doctor/monster combo of all time: Dr. Jekyll & Mr. Hyde!  The parallels (and power source) are surprisingly similar.
