Grimm D. Reaper (Earth-616)

Grimm is the current Death's biggest rival ever and older brother. He was born far before his younger brother Death and got his hands on the first twin demon death scythes called Dust and Despair.

History
Grimm was the older and much more powerful of the two original Death's and one half of the reason there are two names for Death; Death and the Grim Reaper. Grimm's type of "madness" is rage and when he is around even the slightest amount of "madness" he becomes extremely enraged and is liable to attack allies as well as his enemies which makes him an extremely high level double edged sword when fighting Kishin. Though he never killed anyone and lived to regret it, but he has killed many people some would consider innocent.

Physical Capabilities
Physically he is easily the most powerful being in the Soul Eater Universe. Compared to other Universes such as the Dragon Ball or Asura's Wrath Universes he is stronger than any of the characters in either by quite a lot.

Soul Capabilities
His Soul is by far the most powerful of all beings in the Universe. He can fly using his Soul Wavelength and can also use various Soul Wavelength based techniques. When using his Death Orb he has unlimited power over the universe.

Powers
Body of a Shinigami: Grimm's body is that of a Shinigami, so many things that affect the human body are trivial to him. He is unaffected by most weather conditions such as the UV Rays the sun emits which can be harmful to the average person. He is also unaffected by poisons, has very fast healing, etc., etc., etc. Death Orb: It should be noted that the Death Orb is an invincible relic that grants the person that possesses it enormous power. It should also be noted that the Death Orb cannot be simply taken or stolen. It has to be given.
 * Reaper Form: Due to Grimm having such immense power as a Shinigami he has ascended that of a Reaper_Form_with_Death_Wings_and_Harvester.jpgar Shinigami. In this form he resemble the common depiction of the Grim Reaper. He gains immense physical capabilities able to easily destroy people of Goku's caliber. If he's hurt or even destroyed he can completely reform from a single memory, he is virtually impossible to defeat because he can regenerate almost instantly.
 * Superhuman Strength: Grimm has almost limitless strength which is in the planetary level, regularly but when in his Reaper Form it's truly unlimited.

 * Space Warping: It allows Grimm to warp space in any method he sees fit.
 * Existence Erasing: It allows Grimm to erase a person, place, or thing from existence.
 * Black Cosmic Energy: Black Cosmic Energy is a type of energy that allows Grimm to create and control Black Holes. Since they are made by the Death Orb they are far more powerful and larger than regular Black Holes. The fact that one of these artificially created Black Holes is capable of destroying whole Galaxies is incredible... other abilities include cosmic storms such as gamma bursts, super and hyper novas, meteor showers.
 * Death Sense: It allows Grimm to immediately sense when a friend is going to die and how, in-order to avoid it.

Offensive

 * Quasar: Can create a super massive black hole with a frontal absorption. It is capable of destroying up to a whole galaxy.

Abilities
Master Scythe Meister: Grimm is definitely the single absolute greatest scythe meister ever, he is a legend

among legends.

Near-Perfect Strategist and Tactician: Grimm is almost completely perfect strategist and tactician.

Perfect Acrobat: Grimm can do any acrobatic maneuver with no difficulty what so ever.

Death Scythes
Dust: Dust at her base form is extremely powerful even without her meister, Grimm. Her base form allows her to sever body parts like a normal scythe but the difference is when Dust severs a body part it turns into smaller than molecule sized dust that cannot grow back with any supernatural healing or regeneration capabilities. Despair: When Despair cuts anyone it fills their mind, body, and soul with extremely deep feeling of despair, regret, and fear, (which can create a variety of effects like massively weakening any that get cut) this effect will affect anyone even if the said person doesn't or even can't normally feel this way. It should be noted that Despair looks exactly like Dust in all four variations.
 * Witch Hunter Ability (Dust Blast): When Dust uses her Witch Hunter Ability she gains flaming red ancient Grim Reaper symbols and lauches up to 100 blasts (all expanding with distance) of dust which is so dry it turns anyone caught in it into smaller than molecule sized dust. Anything destroyed by this technique cannot grow back with any supernatural healing or regeneration capabilities. It can reach up to 100 meters with absolute minimal effort but can go much further the more effort put into the technique.
 * Genie Hunter Ability (Dust Wave): When Dust uses her Genie Hunter Ability her blade turns black and Dust_Wave.png still has flaming red ancient Grim Reaper symbols and launches a huge wave of dust which is still so dry it turns anyone caught in it into smaller than molecule sized dust. Anything destroyed by this technique cannot grow back with any supernatural healing or regeneration capabilities. It can reach up to 10 km with absolute minimal effort but can go up to one whole solar system range and it can reach that distance almost instantly.
 * Dust_Storm.pngKishin Hunter Ability (Dust Storm and Wave Combo): When Dust uses her Kishin Hunter Ability she becomes entirely black except for the still flaming red ancient Grim Reaper symbols while the attack is active. It creates a huge storm of dust that is so dry it turns anyone caught in it into smaller than molecule sized dust. It is essentially a settup technique because it's made to block an opponent from exiting (should be noted the attack has a core without dust made for battle without any interruptions). It can be used in conjunction with a huge wave of dust that is again so dry it turns anyone aught in it into dust (this conjunction technique is undodgeable due to it covering the entire empty core of the storm). Anything destroyed by this technique cannot grow back with any supernatural healing or regeneration capabilities.
 * Witch Hunter Ability (Aura): When Despair uses her Witch Hunter Ability she gains an aura around herself (reaching around 100 meters) that has the same effect as Despair's basic cutting ability except this one specifically target enemies to Grimm which is known through Grimm's ability to sense killer intent and any negative emotions (should be noted that when this aura affects anyone they also become a vessel for this aura which enhances the range by another 100 meters).
 * Genie Hunter Ability (Super Aura): This technique is essentially a bigger variation than Despair's regular aura (reach up to 500 meters) with the same effect.
 * Kishin Hunter Ability (Grimm Aura): This technique is again essentially a bigger variation of Despair's super aura (reaching up to 1 000 km's) except the only difference is that this version not only fills their mind, body, and soul with an extremely deep feeling of despair, regret, and fear, the effect is so severe that the affected people either kill themselves or instantly retreat or forfeit depending on the willpower of the affected person.

Fusion
Harvester (a fusion of Dust and Despair): After Grimm learned the Fusion Dance from Goku, he immediately taught it to Dust and Despair. When the learned it Harvester was born because she's a weapon he can stay fused for only 15 minutes but in that time she have unrivaled power. She can use all techniques of Dust and Despair but they are much worse. Harvester being made of both Dust and Despair goes through the exact same changes in all four variations. It should be noted that comparing Harvester to Dust and Despair is like trying to compare Videl and Hercule with Goku in GT while in Super Saiyan 4.

Random Abilities
Death Wings: Both Weapons and their fusion form can grow 2 skeletal wings from Grimm's back that allows them to fly and move much faster as well as jump higher. These wing also attack and defend as their meister does. The fact that they are near indestructible and constantly age things that come into contact with them makes them excellent at both.

Weapon Manifestation: Both Weapons and their fusion form can manifest weapons anywhere on their body and can use their abilities without the need of a meister making them very deadly.
