Frank Castle vs Apokolips
Frank Castle vs Apokolips. Frank Castle gets a GL ring and is taught for 100 years by an experienced (not the very best but a good GL) Green Lantern. He then gets taught by Big G on the construction and maintenance of the punisher robots, Frank then becomes an expert specfically in this area. Frank Castle is then given 10 Punisher robots.
Frank gets a map of the DCU and Apokolips, the map only gives basic information. He is teleporeted to an isolated area of the DCU and has two years to construct a plan to conquer Apokolips. 1 year to gain resources and tech (uses DCU map but not Apokolips). 1 year to apply the resources to the actual attack (then gains the Apokolips map).
Darkseid is informed 1 day before Frank attacks. Frank has been told if he suceeds he gets his family back.
P.S. Robots are immune to defeat via matter manipluation, or trapster substance in internal circuirty.
