Heinrich is a "passive" cyborg, which means that none of his implants require a power source.
Metallic rods and plates are often surgically implanted to reenforce broken or cracked bones. Most of his bones were surgically reinforced with hypoallergenic, titanium alloy prior to any fractures. His eyes' lenses are artificial and are multipurpose filters, which alters and protects his vision.
Certain genetic mutations were spliced into his DNA postnatal. The goal was to enhance his blood, skin, skeleton, muscles, heart, senses, and nervous system.
The side effects: low body fat, higher metabolic rate, higher body temperature, robust appetite, higher density (interferes with swimming), and "normal" people seem slow.
Caffeine and ethanol are not his friends. No. They are not.
