Synopsis for "A Taste of Madness!"
In an elaborate scheme of the Skrulls and their mysterious Masterlord, Super-Skrull and Kl'rt, Rick Jones is framed for the murder of Dr. Benjamin Savannah and brought to a run-down police precinct. Using Super-Skrulls invisibility as well as other Skrull technology, Mar-Vell and Rick are led to believe that many of his long-time friends and foes have returned and are attacking him. Rick and Mar-Vell identify the ruse, and Mar-Vell attacks the Skrulls. The building collapses in the battle and the Skrulls escape. To be continued...
