Heidi (ハイジ, Haiji) is the main protagonist of the Hungry Joker manga series. He is a young scientist that was able to awaken the power of his mysterious Black Apple.To find out about his unknown past, Heidi joins the White Joker organization alongside his assistant Chitose Toriiooji.He is called Barschheit (バルシュハイト, Barushuhaito) by Nacht, his older brother, and the only person that Heidi recalls from his past's memories.

Standard Equipment: Newtonian Apple

Being a Eureka adapter, Heidi is able to use these items, and the one of them that's in his possession is the Newtonian Apple, which grants him access over the ability to manipulate gravity.The Apple takes the form of an ordinary apple with a single stem protruding at the top. One main difference is that the apple is black in color. It also has a distinct feature located at the lower half of the apple. The feature is a horizontal curve line which extends across the apple's front surface. The said line also has seven vertical lines spread across with different lengths between each others. This particular feature gives off the vibes that the apple is actually "smiling".

Intelligence: High, Heidi is a very intelligent person, managing to become a renowned and credited scientist at a so young age, working for a certain Research Institute and having a personal sponsor. He is capable of conducting several researches by performing a wide series of scientific experiments, mainly because of his strong awareness and high capacity of deduction. He managed to learn the powers of Newtonian Apple by himself, while some users had to be taught or research about how to use them, showing that Heidi has a reasoning above average. He has a quite good scientific knowledge, which helps him in his researches and to make up strategies when fighting against his opponents. His logic way of think also led him to discover many possibilities about the powers of Eureka, such as combination or multiple use.

Weaknesses: His powers have a time limit

Notable Attacks/Techniques:

  • Gravity Pull: Heidi can increase the attractive force of a certain body to make objects to be thrown at it with great force.This also makes him able to increase his own gravity to make opponents and objects to be attracted to him, prompting him to launch physical attacks.Additionally, he can intensify the gravity of the Earth to make the target(s) "heavier" and restrain them, with a force strong enough to crush the ground itself, creating a crater.
  • Gravity Intensification: Heidi is able to increase the intensity of gravity force exerted by the planet on their target(s), creating an attractive and repulsive force.The same can be done with the gravitational attraction between him and/or other bodies.
  • Gravitational Wave: Heidi was shown to be able to perform this movement only after taking two successive bites of the Apple, thus enhancing his powers. He waves his arms down and makes a wide linear area in front of him to be crushed by a strong gravity.
  • Gravity Push: Heidi is able to make objects to be repelled by him, changing the amount of gravitational force between them and himself, which effectively makes the object fly away with great force from him. It becomes useful when Heidi has his movements restrained by something like a rope.
  • Gravity Nullification: Heidi becomes able to nullify the effect of a planet's gravity to, for an example, allowing him and other objects to float.The power degree of this nullification, that is, the limit of weight that Heidi is able to annul, depends on his experience and strength, but it's known that even enormous parts of buildings can be lifted by the his power even after taking a successive bite of the Apple.
  • Flight: This ability can be used to allow him and other bodies to levitate above the ground. Once in Zero-G, Heidi is able to fly around freely, matching attractive forces to the direction where he is going to. While flying, Heidi can deliver powerful flying attacks enhanced by gravity, that were strong enough to break Killed's mask and make him bleed.
  • Wall Walking: Heidi can create a pseudo gravitational field into any objects, allowing him to attach himself and others to any surface where they can walk and stand up on it. He can do it at the same time as lifting the very object, what makes it a floating surface for Haiji.
  • Air Slicer: Heidi can even control the gravity exerted on a certain mass of air, what allows him to use it as a slicer, mainly when applying a sudden high amount of gravitational force in a smaller area. He does this by pointing his hand upwards and then swiftly waving it downwards, effectively tracing the region cut by the Slicer.
  • Gravitational Controller: Through a precise application of multiple vectors of gravitational force strategically placed on his body, Heidi is able to control his own movements by forcing them. It becomes useful for him once he's with his movements restrained.
  • Absolute Gravity Manipulation: Heidi's control of the gravity reaches to a level where even light, an electromagnetic wave whose mass is immeasurably small and only explained by Einstenian's General relativity theory is within his power's range. Such ability implies that the there are no entities that can't be trapped by his powers.
  • Black Hole: Heidi stretches his hand forward and concentrates an enormous attractive force in a single point, therefore efficiently creating a small black hole, that is impressively under his complete control, absorbing only what Heidi desires in a swirl-like pattern, including light. A quick change of the target being absorbed also can be useful for Heidi to prevent that target from running away.
