## History

Not much is known about his backstory, but Master Onslaught revealed his real name was Martin Pierce and was a normal human. He used to work for the Pandora foundation, group of founded by the government around the world to stay about the multiverse and beyond and contain beings that could be a threat to humanity or other living organism (if they're evil of course). He was one of their top researcher and bio engineer, inventor, and basically one of their top scientist during the end of the Great Depression until one of his experiments were too "inhumane". He was making his own species through human and animals and other anomalous creatures by removing and replacing each of their body parts, organs, and DNA while still being alive. One of the animals belonged to his 8 year-ol daughter Madison Pierce, when she learned about what happened to her pet she was traumatized. She yelled out why he did it and his excuse was "for Science". Showing no remorse he told his daughter that she won't understand the things he'll do. He found out that he could make his new species, so he killed his own daughter and his own wife named Katie and his son named Norman. Learning on what he had done and was about to do, the foundation's leaders and had him arrested. Put on trial, he was forced to explain why he was making a new species. He told them that he wanted to create super master race as he believed humanity had their chances to involve and become the dominant species.

He was kicked out of foundation and was about to be sent to prison and receive a death sentence for his twisted science project. It wasn't until the evil entity known as Grandmaster Chaos sent him free, he was offered to join him and become powerful. To insane his own skin and to continue his idea on making a master race. He was granted cosmic powers to rival that of Malroc. He changed his name to Mastrion, and was sent to live in the Doom Realm. In the Doom Realm, he discovered the existence of a multiverse, he was fascinated by it and see that if his master race succeeded he could use them to overthrow many empires and become an all powerful being. During his time, he designed new technologies and knew ways to create poison, diseases, weapons, and other kinds of "toys" as he calls them. He helped conquer worlds for the Grandmaster, and had used one of his death plagues to cause an entire species to go extinct, he caused many cities to become uninhabitable, and used the dead bodies of fallen warriors to become one of his genetically enhanced "War Mongers". He finally made a living organism but it was a pacifist, and it wasn't very intelligent. Sick of his new creation he used it for turtler via mutating it with a horrible virus that he made.

He became so evil that Grandmaster made him the one and only champion. As a champion he conquer a whole universe and used it as his "Lab" Meaning he tested his own weapons, plagues, and diseases on the poor inhabitants of that universe. He also stated that he helped the nazis (along with Malroc who also supported the axis powers) on making the Holocaust, as he view the jews inferior showing his true nature to other ethnic groups. He meet the Sicorions who are led by Draxxus Bane, he and bane made an alliance as they are also supremacist. He continue on his creation of his "Master race", he even grew egotistical over the years, and was reviled across the omniverse giving him the attention of Aka Manah, Nekrozoth, and other evil beings. He had gained his reputation as one of the worst and reviled beings in the entire omniverse.

### Legends Online

during the Omniversal War, the planet Eldor was split into three pieces (Deva, Reva, and Neka), revealing a divine gateway holding the Devil's Sum (which is basically the Anti-Life Equation but more powerful) on the other side. All factions (Prime Omegas, Prime Alphas, Red Empire, Chaotic Elites, etc.) are now fighting for control of these little shards, called keys, which could open the gateway. Master Onslaught appears to the player and gives them a mission to accomplish an if they succeed he would reward them. Once all missions are complete, however, the player will have to fight against Onslaught himself and his armies as a secret boss.

## Multiversal Legend Film

Master Onslaught is the main antagonist of the 2020 sci fi adventure film Spark. He is a traitorous mad scientist turned multiversal conqueror who seek to capture Jack Spark so he transfer his body into Jack's body and become immortal. He also seek to become the most intelligent and powerful being in existence.

## Personality

Martin was a strange, almost ominous fellow from the beginning. During his year as a scientist and a bio engineer, he done some twisted mess up experiments that even Aka Manah was disgusted about it. He is callous, twisted, misanthropic, and completely heartless. He shown that he is truly a complete monster as he caused an entire species to go extinct, killed his whole family so that he can "continue his experiments", and enslaved an entire universe and made it as his Lab. Meaning he tested his own weapons, plagues, and diseases on the poor inhabitants of that universe.

He is sadistic, vile, and genocide as he view the Sparxians inferior and an example of why he wanted to make a better master species. He is even egoistical as he believed that the omniverse belongs to him and his new master species. He is Torturous, Megalomaniacal, cruel, inhumane, arrogant, ruthless and psychopathic individual who craves ultimate power and knowledge. He is fully aware of his diabolical nature and takes pride in his evil, embracing his destructive ways as he believed that his new Master race and himself are the one ones that should rule the omniverse. He is as narcissistic and even as intelligent as Malroc as they both are embodiments of destruction and can be very vicious as they please as shown when he butchered an entire city of innocent humans from an alternate earth. He is one of the people that killed jack Spark's races known as Sparxians to extinction (along with Nekrozoth and Malroc) as he was ordered by Nekrozoth during his time working with him by using his new disease called the "Silent death" and had mixed it with Malroc's army to spreads it.

He is so sick that he tortures his own creation via infecting it with a strange disease that horribly mutated it, If this was not bad enough master Onslaught experimented on many, many beings across time and space, seeking to perfect a virus that would wipe out all life-making him a would-be-universal destroyer. Since he took a perverse fascination in agonizing ways to mutate and harm others, needless to say he was among the most brutal and dangerous threats to the heroes.

Though he tries to justify his means by saying it was for science, he actually did the horrible things because he find it enjoying and see that everyone in the omniverse serve no purpose as he believed himself to be of superior blood. he can be sarcastic and does possess a sense of humor of his own but rarely shows his comedic. He see his enemies as more than test subjects to test his new creations on and doesn't seem to take his enemies seriously as he can underestimate his foes but not too much for him to defeat him or foil his plans.

## Trivia

* He said that it was his idea of creating the atomic bomb.

* His physical design draws inspiration to The Maker, AKA Reed Richards from the Ultimate Marvel universe.
* He is shown to be a foil to Jack Spark (along with Chernobog) similar to how Nekrozoth and Malroc are a foil to Legend. like Jack who is pure good and believes in equality, Master Onslaught believes in supremacy and is a complete monster. Jack has friend like Master Onslaught who uses his so called "friends" as pawns or even worse, his victims for his twisted experiments. Jack (along with Hyperiel) is the protector of all living things while Master onslaught is one of the great enemies to life itself.
