Formerly an elite psychiatrist, Cannibal now believes that eating human flesh gives him supernatural powers.  Perhaps so.  Regardless, he is a force of madness, not only brilliantly intelligent but also highly unpredictable and intensely fatally charismatic.  He employs an eclectic group of weird tech devices whose origin is unknown (although he makes some of them, though others he does not.)  It is said he has the Devil’s Luck, where the more terrible things he does, the more favor goes his way.  Others say that his primary ability is to draw people into his insanity.  He has been called “depravity incarnate.”  Even other supervillains fear him and what he might do to them.  He has reputedly been killed a dozen times.

1. Psychological Manipulation:
- As a former elite psychiatrist, he understands the human mind like no other. He can exploit weaknesses, phobias, and traumas, manipulating individuals into doing his bidding or driving them to the edge of sanity.

2. Devil's Luck:
- The uncanny way events seem to conspire in his favor. Whether this is due to meticulous planning, adaptability, or simply luck is uncertain.

3. Techno-Mastery:
- While he personally creates some of his devices, the true potential of his gadgets remains a mystery. They can range from tools that emit frequencies that cause unease or paranoia, to devices that can temporarily paralyze or incapacitate foes.

4. Fatal Charisma:
- His charisma is his weapon. People, even those who fear or hate him, find themselves compelled to listen to him, and many are swayed by his arguments, or at least distracted by them.

5. Master Tactician:
- With his brilliance, he can predict many steps ahead, setting traps for adversaries and using his surroundings and circumstances to his advantage.

6. Emotional Intelligence:
- Cannibal can read people with uncanny accuracy, picking up on micro-expressions, body language, and voice fluctuations. This skill aids in manipulation, deception, and in predicting an individual's next move.

7. Resilience:
- While not superhuman, he has an uncanny ability to survive situations most would not. Whether due to preparation, luck, or sheer determination, he's tough to put down permanently.

8. Fear Aura:
- Without any supernatural element, his mere presence can induce a palpable sense of dread. Stories of his deeds precede him, and the weight of his reputation amplifies the fear.

9. Crafting Nightmarish Scenarios:
- Using his understanding of the psyche, he can craft situations or encounters that play on individual or collective fears, causing chaos and panic.

10. Deductive Reasoning:
- His intelligence is razor-sharp, allowing him to piece together information quickly and use it to his advantage.

The horror of Cannibal isn't in overt supernatural powers but in the depths of human depravity, manipulation, and intelligence harnessed for malevolent intent. His devices, his intellect, and his unpredictability make him a formidable and terrifying opponent.
