Masterminds are considered geniuses among geniuses; in other words, they are among the most intelligent beings in existence and are characterized by a personality in which they will plan things to amazing lengths and always have a backup plan. They are often extremely difficult to catch or defeat due to their incredibly complex schemes and forethought, but they are not impossible to thwart as many heroes have done so.

Pure Evil masterminds are exceptionally dangerous since they use their intelligence to commit and get away with heinous acts, no matter how common or uncommon it is. Especially if they started as an average citizen and for whatever reason achieved their mass intelligence.
