Wolfram is a tall man with very dark, red hair. His face has dark patches of skin, which cover his mouth, nose, eyes, and part of his forehead. He also has a scar on his left cheek. He wears a very large white coat, with light gray cuffs and lining, along with gray combat boots, baggy sweatpants, and a combat vest. He also wears dark brown gloves.
Wolfram is a cunning person, being able to manipulate people into doing what he wants. It's also been shown that he shows little emotion for close to anything, and only strives to overturn the hero society.
Not much is known about Wolfram's background prior to the events of The Two Heroes.
Wolfram and his men posed as actors who hired by David and Sam to aid them in orchestrating the villain attack on I-Island in order to steal back their greatest invention - a headset that maximizes the power of its user's quirk. Whereas David, who conflicted with the plan, simply wanted to retake the headset so All Might can maintain his status as a hero and keeping the world save with it (as unknown to him, the hero has passed his quirk to his apprentice Izuku Midoriya and only have fewer ember of his former powers), Sam intended to sell the invention to the villains so he can achieve fame and fortune both he and David denied of. Unknown to either of them however, Wolfram himself is an actual villain who genuinely sought to kidnap David and forced him to mass-produce the said invention for his own purposes.
Whem Wolfram and his men making preparations for the extortion, he received a contact from All For One, who intrigued by his scheme as it also involved his nemesis All Might. Since they have a common enemy, the Symbol of Peace, Wolfram agreed to have One for All endowed him a quirk which enable him to amplify his muscles, and thus counteracted his weakness at close range when manipulating metal.
Metal Manipulation (金属操作 Kinzoku Sōsa?): Wolfram's Quirk allows him to manipulate metallic material by making contact with an iron surface. It can be used for offensive and defensive purposes by creating flexible iron pillars to crush his targets and create tall, sturdy walls to defend himself and trap his opponents in.
Muscle Augmentation (筋肉増強 Kin'niku Zōkyō?): This Quirk was given to him by All For One, and allows Wolfram to increase his muscle mass and physical strength, as well as alter his appearance, evidenced by his hair protruding, similar to All Might. This Quirk is very similar to One For All, but not as powerful.
- Handgun: Wolfram carries a loaded handgun with him.
- ”Wolfram” is the German name for Tungsten, which is a reference to his metal-based Quirk.
- The nature of Wolfram's Metal Manipulation Quirk heavily resembles the mutant Magneto from the X-Men comics and movies.
