Back from the Dead: He somehow came back to life 5 years after his 'death'.

Ax-Crazy: When told that the Tachyon cannon he absorbed could kill humans within a hundred miles, Malware states that he considers that 'a bonus'.

The Assimilator: His ultimate goal is to assimilate Galvan Prime and become a living planet.

Arm Cannon: His right hand became one after he absorbed the Tachyon Cannon.

Eventually, he was the one whom Ben needed to stop.

Arc Villain: Of the first two story arcs, having recruited Khyber to collect the DNA required to complete the Nemetrix.

He notably retains an air of dread and fear around him that makes him stand out in Omniverse compared to many others. Killing Feedback, more or less, for half a decade is a very personal blow and Malware of one of a very few number who Ben has shown to be afraid of.

Arch-Enemy: While only appearing in one series Malware's many battles with 11 and 16 year old Ben and the level of terror, dread, and disdain between the two gives Malware a claim to the title.

However, once he got upgraded, he became a straight villain.

Anti-Villain: He started out as a very twisted Type II.

Had the series continued after arc 8, he would have been featured as a potential member of the new Negative 10.

Aborted Arc: The end of 'Malgax Attacks' hinted that turning him into a suit for Vilgax may have brought him back to life, but this was the last time he made any sort of appearance before the series ended.

Somehow, he survived and returned to menace Ben years later.

After destroying Ben's Feedback form, he was seemingly killed when Ben overloaded him with the Omnitrix. After that, he vowed to absorb the Omnitrix in order to gain its abilities. Azmuth spent years developing a new Helix in order to cure him, but Malware eventually lost patience and stole it from him, using it to upgrade himself into a form that apparently eliminated his need for energy while retaining his old abilities. As a result, Malware was born corrupted, with the ability to absorb technology and gain its ability instead of upgrading it. He was an incomplete Galvanic Mechamorph created accidentally by Azmuth during the development of Galvan B by shutting down the Helix (the device that created the original Galvanic Mechamorphs) right while he was being produced. Malware is a psychotic Galvanic Mechomorph who serves as the main antagonist in the first 2 arcs of Omniverse.

I do not upgrade others' creations THEY UPGRADE ME! And I will upgrade myself with Azmuth's greatest creation!' mimic and manipulate what others have created. It's all the rest that are inferior! They bend and stretch. VISIONARY! I feel power building inside me! I see a world that only I can create! It was Azmuth who thought me flawed! He gave me the name Malware.
