Villains who obsess over something remarkable, which stands out besides obsessing about power (because obsession with power typically counts as a power-hungry villain or a megalomaniac due to egotism), or greed (because it counts as the obsession over money or treasure). Many obsessed villains are also mentally ill, though some are merely eccentric since they tend to lose control over their feelings in regards to what they are highly interested or worried about.

These type of villains are usually particularly obsessed with the hero themselves.
