Jet Nice Guy (ジェットナイスガイ, Jetto Naisu Gai; Jet Niceguy) is a B-Class Rank 50 professional hero for the Hero Association.


Jet Nice Guy is a cyborg. He wears sunglasses, round shoulder and knee pads and has the letter 'J' printed on the right pectoral of his shirt. He also wears boxing gloves.


When J-City was attacked by the Seafolk, Jet Nice Guy hid inside the evacuation shelter. However when the Deep Sea King attacked said shelter, he was one of the first heroes who stepped up to protect the general public. Such behavior indicates that despite being frightened he was willing to risk his life to protect the people. He also respects his superiors, stating that he was glad to have an A-Class hero help him fight the Sea King.

History Edit

Jet Nice Guy won the lottery and he used his winnings to pay someone to turn him into a cyborg. Unfortunately, the person responsible for turning him into cyborg was not as good as Kuseno, making him massively weaker than Genos. He joined the Hero Association sometime afterwards.[1]


Hero Association SagaEdit

Sea Monster ArcEdit

When J-City was invaded by the Seafolk, Jet Nice Guy hid inside the evacuation shelter along with other citizens. When the Deep Sea King attacks the shelter he, along with All Back-Man, Bunbunman and Sneck try to defend the common citizenry.[2] However, they are easily defeated.[3]

Human Monster Saga Edit

Monster Association Arc Edit

He returns, rebuilt and upgraded for the coming battle.

Abilities and PowersEdit

As a mid ranked B-Class hero, it can be assumed that Jet Nice Guy is a fairly skilled combatant, but, like the other heroes, he hid in the shelter, only to come out to stand against the Deep Sea King after someone else stood their ground. Judging by his appearance and his performance against the Sea King, it can be assumed his cybernetic components are a good deal less advanced than Genos'.
