Powers and abilities
http://batman.wikia.com/wiki/Solomon_Grundy
Superhuman Strength: Solomon Grundy possesses tremendous strength and stamina, the level of which varies with his different incarnations. Sometimes he can be held by a group of normal humans, on other occasions, even Superman has not been able to defeat him.
Superhuman Stamina: Superhuman; Grundy can perform physically strenuous tasks for an indeterminate period of time before tiring.
Mystical Invulnerability: The weird elemental energy that imbues his form with pseudo-life makes him virtually indestructible - he is impervious to bullets, fire, and extreme cold, and can survive indefinitely without food, water, or oxygen. The only thing that has ever been able to hurt him, was the Mist's special toxins, developed to take out Grundy's plant tissue body.
Resurrection: Even when he is destroyed, he has always been reborn sooner or later. The soul of Cyrus Gold enjoys his pseudo-life through Grundy, even though Gold's whole personality is never present in Grundy's "life". Grundy's personality differs from incarnation to incarnation, but he seems to retain some memories of his experiences from one time to the next.
Energy Absorption/Manipulation: Grundy has also proven to be able to absorb certain forms of energy and manipulate them at will. This ability has always been subconscious to the point of being accidental, though, but it would suggest that Grundy is even more powerful that he has the intelligence to realize.
Plant Control: The version of Grundy that ended up on the blue planet gained normal human intelligence, and made contact with the Green, thereby being able to control the planet's plant life.
Strength level
Assumed to be on par with Superman's or even surpassing him in strength. Grundy's upper strength levels have fluctuated depending upon his present incarnation.
Weaknesses
Grundy's below average intellect makes him easy to fool and manipulate. In addition, in Arkham City, he needs electricity funneling devices to continue to function, meaning if his electricity is denied, he will end up being weakened and eventually knocked unconscious. In addition, in the same game, his heart is also his weakness, destroying it would result in him shutting down for good.
Powers and abilities
http://bleach.wikia.com/wiki/Kenpachi_Zaraki
Kenpachi did not attend the Shinō Academy. He is also the only captain that does not know the name of his Zanpakutō. Because of this, he cannot use his Bankai. In addition, he has no apparent skill (or at least interest) in Kidō and Shunpo. However, he more than makes up for his faults with his sheer power and endurance, easily making him one of the strongest Shinigami in Soul Society.
Master Swordsmanship Specialist: Kenpachi's skill with his sword was honed to a masterful level, due to the lawlessness of Zaraki district, letting him strike multiple times with changes of attack type (from slash to pierce) without any difficulty. His unpolished skills and strength with his sword make it so he always fights with one hand free. He only uses both hands when faced against opponents he feels will beat him otherwise, as shown with Nnoitra and momentarily Ichigo. His extreme cutting strength is also evident as he is capable of easily cutting through an Espada's Hierro, which is harder than steel, as well as slicing apart a skyscraper with a mere flick of the wrist. As the Captain of the 11th Division, which specializes in sword fighting, he is one of the most, if not the most, proficient swordsmen in all of Soul Society.
Kendō: Kenpachi has also displayed considerable knowledge and skill in Kendō (a requirement Yamamoto put Kenpachi through before officially joining the Gotei 13), though Kenpachi despises using skills and techniques learned from another source.
Ryōdan (両断, "Bisection"): A technique that Kenpachi uses when he is gripping his sword with two hands. It allows one to split an opponent down the middle.
Hakuda Expert: While preferring to use his blade in battle, Kenpachi has demonstrated several times to be very dangerous barehanded as well. He can easily catch an opponent's attack with a single hand, perform powerful kicks and take-downs, and has demonstrated superb skill with throwing weapons.
Vast Spiritual Power: Even by a captain's standards, his Spiritual Pressure is absolutely monstrous. In fact, it is so great that Kenpachi can fight on par with two other captain-level opponents without using his full power, even when he is wearing his energy-sealing eye patch and his opponents release their Zanpakutō's Bankai. His spiritual energy has been shown to be powerful enough to affect entire areas to the point of disrupting energy attacks from enemies, and cause others from seemingly miles away to enter a state of paralysis and confusion. Similar to Ichigo, when unleashing a strong enough surge of energy, it becomes visible and yellow in color, sometimes with the appearance of a skull.
Damage Resistance: He can also use it as a sort of armor, making it impossible for him to be harmed by nothing less than the most skilled or powerful opponents. This is first demonstrated when Ichigo tries to cut Kenpachi at the start of their fight. Kenpachi allows Ichigo to strike him, yet not only does he fail to cut him, but Ichigo's hands start to bleed because of it. This is comparable to an Arrancar's Hierro.
Shock Wave: He has also demonstrated enough control to focus and unleash his spiritual pressure in the form of a powerful shock wave. When using both hands, his shock wave can cause a huge radius of destruction.
Highly Perceptive Combatant: Despite his seeming disregard for any strategy in his fights and his self-admitted aversion to thinking during battle, Kenpachi is a very insightful man, regularly showing more understanding than one would expect. Even Byakuya was impressed by Kenpachi's ability to understand things he has no personal experience with. He is very adept at finding and exploiting weaknesses in his opponents' techniques, such as in his battle with Kaname Tōsen, where he subdued the latter's Bankai while armed only with a Zanpakutō and the one sense that was left accessible by Tōsen's Bankai at the time - that of touch. He is also adept at adjusting to his opponent's attack patterns and battle methods to better counter them. While he admits to having no sanity or common sense, Kenpachi is actually very perceptive and notices traits in people that others wouldn't notice and sees what drives a person's actions. For example, he correctly singles out Kaname Tōsen and Gin Ichimaru as the only captains who are afraid to die. He has also demonstrated keenly sharp intuition to incoming danger, as shown from being able to repeatedly dodge Tōsen's assault while still affected by his Bankai.
Kenpachi using his strength to hold back Nnoitra's blade one-handed.
Immense Strength: Perhaps due to years of combat experience and time on the battlefield, Kenpachi has a very large degree of physical strength, most commonly displayed by his ability to fight back his opponent's attacks with a single arm. Repeatedly, he has shown clear evidenced of his strength from acts like kicking Tōsen through a building and slamming Komamura over his shoulder with one hand in their battle, as well as when he grabbed Ichigo's giant sword barehanded and reeled both him and the sword in for an attack. He also demonstrated his strength when he rammed through a building fighting Ichigo. With just his bare hand, Kenpachi was also able deflect the fifth Espada, Nnoitra Gilga's Cero. His sword attacks are also powerful enough to cut through Yammy Llargo's released state Hierro to remove his limbs in a single strike and knock the giant Arrancar off his feet. He is even able to fend off an opponent's gigantic sword with a single hand.
Immense Speed: While he possesses no known skill for Shunpo, Kenpachi has shown to be deceptively fast for his size and build. However, in the Anime, Kenpachi's sudden bursts of speed have occasionally worked like what appeared to be Shunpo.He is also seen using Shunpo in his fight against Yammy. Thanks to his tremendous raw power, Kenpachi's leg strength allows him to more than make up for his lack of Shunpo, allowing him to move fast enough to instantly close a huge gap of space between him and the opponent and even seemingly disappear from sight. In battle he is able to strike with incredible speed in rapid succession, making it highly difficult for his opponents to find an opening and counterattack.
Immense Endurance: His physical strength is matched by his resilience. Kenpachi has been shown to easily ignore most of the injuries he's sustained in battle (much like a berserker), not suffering any debilitation despite having multiple slash wounds in his body. He even allowed himself to be stabbed during his fight with Tōsen, just to grab Tōsen's blade in-order to break his Bankai's effect. During his battle with Nnoitra he suffered numerous slash wounds and was even impaled with no visual impairment of his fighting abilities despite the Espada noting that most people would have already been dead at that point.
Immense Durability: As resilient as Kenpachi is, he is as hard to damage. During his battle against Yammy, while focusing his attention on Ichigo, Yammy delivered a powerful blow with his massive fist, launching Kenpachi several meters and smashing into a large pillar. Despite the impact, Kenpachi quickly emerges unfazed, claiming it
Zanpakuto
Kenpachi's unnamed Zanpakutō.
Kenpachi does not know the name of his Zanpakutō, and is the only captain of the Gotei 13 who cannot perform Bankai. It appears that after his fight with Ichigo, Kenpachi wishes to learn more about his Zanpakutō because he wants to become stronger. He can also identify with the pain of not having a name to be called by, however he is not yet capable of communicating with his Zanpakutō, and it is implied that he continually tries to learn from it so that he can just achieve a new level of power. Zangetsu notes that Kenpachi's disharmony with his sword causes the two to damage each other's powers and that he cannot hear the cry of his sword because of that. As it is revealed in the Hueco Mundo Arc, he has at least communicated with his Zanpakutō on some level after his loss to Ichigo. During his fight against Nnoitra, he refers to his Zanpakutō as "him".
Shikai: Despite not knowing its name, his Zanpakutō is in a constant release state much like Ichigo's Zangetsu. The blade is much longer than that of a standard Zanpakutō, roughly the size of a nodachi with a guard that extends inward from its center similar to a shinai. The hilt is white although most of it is wrapped in bandages, as is his sword's sheath. Despite constantly being in its Shikai state, Kenpachi’s Zanpakutō does not grant him any additional abilities due to their lack of communication.
A further consequence of their disharmony is that it leaves the Zanpakutō with little spiritual energy and becomes easier to damage, ironically making its appearance a reflection of Kenpachi's own practice of weakening himself to fight others on an even level: it is a chipped and seemingly worn-down blade. Despite its appearance, it is easily capable of cutting through most objects. This is demonstrated when he stabs straight through Ichigo's Zanpakutō and later slices a building in half with careless effort after releasing the full force of his spiritual power.
Shikai Special Ability: Unknown
Bankai: Not Achieved.
