Caesar is a scientist with immense scientific and chemical expertise, as he was Vegapunk's second-in-command and caused a chemical weapon explosion that rendered Punk Hazard a barren wasteland. He was able to turn normal humans into giants, a feat that even Vegapunk could not accomplish, though Caesar has resorted to illegal and inhumane methods that Vegapunk considers unacceptable (by forcing vast amounts of dangerous drugs down their systems), and the fact that the children used would expire within five years from the continuous experiments,[17] which led the Marines to refuse to acknowledge him to be superior to the head scientist.[10] He also uses the highly restricted drug NHC10, though his authorization on its usage is illegal, as he is a criminal, and he used it as for its addictive means instead of medicinal purposes. He is also in the possession of another unnamed drug, that relaxes muscles and makes it unable for the person, who the drug has been injected into, to talk or stand.[11] All this earned him recognition as the world's leading expert on weapons of mass destruction.
