History
The Kaiju Formula was the result of Project: Troubleshooter's attempt at recreating Abraham Erskine's Super-Soldier Serum. Due to the difficulty of recreating said formula, most of the knowledge gaps were filled with hacked and reverse-engineered versions of a dozen of other transformative substances. The final result included Gamma enhancements, Mutant Growth Hormone, Pym Particles, and the Connors Formula.
The first and only known subject injected with the Kaiju Formula was Corporal Todd Ziller, who was turned into a giant reptilian monster.[1]
Following Ziller's depowerement, the lingering traces of the Kaiju Formula in his body were used by Victor Vandoom to improve his monster serum.[2]
