Wolfram is a tall, bulky man with dark red hair and yellow eyes. Dark patches of skin cover his mouth, nose, and extend across his right eye, and there is also a scar on his left cheek.
Wolfram wears a large white coat with gray cuffs and trimmings. He also sports combat gear that his entire squad wears, including combat boots, dark pants and a combat vest. He covers his hands with brown gloves and sports a metallic mask that covers his scars.
Wolfram is an avaricious and manipulative Villain who will crush anything or anyone to get what he desires. He desires money and works as the leader of a troupe of thieves. They even masqueraded themselves as fake villains for hire to earn the trust of David Shield just so they could steal his invention.
Wolfram cares little for anyone other than himself. He tries to kill Sam even after the latter kept his end of their agreement. Wolfram looks down on others and enjoys taunting them. With help from All For One, Wolfram believed he could defeat the No. 1 Hero All Might. He enjoys tormenting people by mocking their heroic decisions or inflating their villainous ones.
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 bears a striking resemblance to the mutant Magneto from the X-Men comics and movies.
