Powers
By consuming different mixtures of his transformation potion, Calvin Zabo can transform back and forth from his alter-ego of Mister Hyde. The chemical process is hormonal in nature, causing the cells of his anatomy to instantly manufacture mutated hormones that induce a physical transformation encompassing his entire figure. Miraculously, over 200 pounds of bone and muscle tissue are added to Zabo's body, and his body’s dense flesh then provides him some degree of protection and he possesses vast superhuman strength and stamina. 

Abilities
Zabo was a brilliant medical research scientist, although these skills are lost in his Hyde persona. Mister Hyde, however, is a formidable hand-to-hand combatant, though he has not had any formal training. He tends to rely on street fighting techniques that allow him to make full use of his great strength. 

Other Info
Calvin Zabo was a brilliant, but amoral, medical research scientist. One of his favorite stories was Robert Louis Stevenson's 1886 classic, Strange Case of Dr Jekyll and Mr Hyde. Believing that the experiment in the story could actually be performed, Zabo obsessed over the idea that he too could unleash the beast inside himself. Thus, he dedicated his life to finding a chemical formula to enable him to do so; however, the research for it was incredibly expensive. Therefore, Zabo systematically robbed his various employers, avoiding criminal prosecution by simply changing employers before he got caught. However, his reputation caught up with him when Zabo applied for work with a noted surgeon, Dr. Donald Blake--the secret identity of Thor. He was turned away by Dr. Blake due to his history. Afterward, Zabo vowed vengeance upon Dr. Blake. Thus, months later, when he struck upon the formula, Zabo transformed himself into a Hulk-like creature--Mister Hyde--he immediately returned to Dr. Blake's office to get his revenge. However, Blake transformed into Thor and defeated him. (To learn about Thor and/or Hulk, click on the highlighted name above. Also, Zabo before he changed into Mister Hyde is show in the third picture posted above.)

At one point, Zabo began experimenting on himself, altering his genome. During this time, he impregnated a prostitute named Jennifer Johnson who later gave birth to a daughter named Daisy Johnson. Uninvolved with his daughter, Daisy was put up for adoption after her birth. (To learn about Quake, click on the highlighted name above.)

Later, to get revenge on Thor, Mister Hyde joined forces with Cobra. They were hired by Loki to kidnap Thor's love interest, Jane Foster. However, even with Loki increasing their powers, both Mister Hyde and Cobra were eventually defeated by Thor. Over the years, the partnership of Mister Hyde and Cobra crossed paths with many different superheroes, including Daredevil and Spider-Man.

At one point, Mister Hyde briefly joined with Scorpion against Captain America and the Falcon, but ultimately failed in taking down the two heroes. (Click on the highlighted names above to learn about the different characters.)

Later on, after yet another defeat from Daredevil, Mister Hyde and Cobra ended up in Ryker’s Island prison. Tired of their repeated failures, Cobra decided to sever their partnership. Eventually, Cobra escaped from the prison; however, he took the time to taunt Hyde on his way out, leaving his partner behind. Enraged, Hyde swore vengeance on his former partner. (To learn about Ryker's Island, just click on the highlighted name above.)

Some time later, Mister Hyde was seen teamed up with Batroc the Leaper. The two had succeeded in hijacking a Roxxon Oil supertanker and capturing Captain America--whom they chained to the ship. The tanker was filled with 50,000 tons of liquefied natural gas. As it cruised through the harbor, Hyde and Batroc set it on a collision coarse with the docks of New York City. The resulting explosion of the collision would likely lead to the total destruction of the entire city. Batroc only wanted a huge ransom for the ship and Captain America; however, Hyde, wanted to go through with the plan and cared nothing for the money--just revenge against Captain America and the rest of New York City's population (particularly Cobra) dead. When Batroc realized how insane Mister Hyde was, he secretly loosened the chains holding Captain America, who freed himself and dove into the harbor. As Hyde was busy steering the ship, Batroc turned against him and attacked Mister Hyde from behind. The two then began fighting one another. As Hyde began to squeeze the life out of Batroc, Captain America boarded the ship again and attacked Mister Hyde. During the fight, Hyde broke a pipe and was hit by a high-pressure stream of liquefied gas. Covered by a thick coating of the freezing liquid, Hyde fell off the ship and sank in the harbor.

Later on, Mister Hyde appears alive and joining Baron Zemo's own incarnation of the Masters of Evil. Zemo systematically planned an attack on the the Avengers Mansion with his new team--Namor had taken a leave of absence to reclaim Atlantis; Captain Marvel was trapped in the Darkforce dimension by Blackout; Hercules had been beaten into a coma by Mister Hyde and others; and Black Knight, Captain America, and Jarvis were all captured. In addition, Blackout sent the entire Avengers Mansion in Darkforce dimension. This left Wasp as the only remaining active Avenger to retake the mansion. Meanwhile, Mister Hyde started beating Jarvis to death. Hyde almost succeeded in killing him, but Black Knight managed to free himself and Captain America. They then fought agasint Mister Hyde until a hastily-assembled squad of reserve Avengers arrived at the mansion and defeated Hyde and the rest of the Masters of Evil.

Meanwhile, Cobra had become the leader of the Serpent Society. As part of re-inventing himself for this new position, Cobra sought out the one person that he still feared: Mister Hyde. Eventually, when Hyde had escaped from the prison known as the Vault, he came face-to-face with Cobra. The two fought, but ultimately, Hyde lost to his former partner. Flushed with new confidence, Cobra renamed himself "King Cobra," and the long grudge match between the two seemed to be over. (To learn about the team above, just click on their highlighted name.

Over the next little while, Mister Hyde found himself battling many different heroes and teams including Hulk, Alpha Flight, Ghost Rider (Daniel Ketch), Daredevil, Iron Man, and Spider-Man. At one point, he even received a head injury from an attack that actually limited his ability to transform into his Hyde persona temporarily.

For a time, Zabo was held in the prison known as the Raft. However, when a prison break out was caused by Electro. Zabo emerged from the Raft in his Mister Hyde persona and fought with the New Avengers. Ultimately, however, Mister Hyde was knocked unconscious by Luke Cage and put back in prison.

Later, Calvin Zabo was seen selling a derivative of his Hyde Formula on the street as one of the various illegal substances known as Mutant Growth Hormone (a drug that gave temporary super-powers to normal humans). He distributed his drug through a number of dealers. His operation was prospering until he was tracked down by Patriot to Hyde's own headquarters. Mister Hyde captured the Patriot, but was surprised when the Young Avengers appeared--they were following Patriot. Mister Hyde was battling the Young Avengers by himself, so he eventually injected himself with his own Hormone and became even bulkier and stronger than before. Mister Hyde continued to wreak havoc on the Young Avengers until Patriot injected himself with the Hormone and used his increased strength to also attack Hyde. Noticing the effect of the Hormone had on Mister Hyde, Patriot decided to inject Hyde with an overdose of the drug. This resulted in Hyde's bulk became too much for him to handle, and he collapsed and was unable to move. (To learn about the character and/or team, just click on the highlighted names above.) 

Recently, many criminals, including Mister Hyde, joined the Hood's Gang of criminals who wanted to take advantage of the split in the superhero community (aka Civil War) caused by the Superhuman Registration Act. Mister Hyde and a few others were sent out on a mission to assassinate the Taskmaster. However, they ended up fighting the members of the Initiative. During the fight, Hyde was actually set on fire by Sunstreak, and the would-be assassins were forced to retreat. (Click on the highlighted names above to learn about the characters and/or team.)
