Mimic

Mimic walks back in the room, wearing a broad smile. He laughs as he sits behind his desk and says, "Oh, that was b-e-a-utiful. You guys should have seen your faces. 'Twas priceless, simply priceless." He stands once again and continues, "I'll make this quick so we can get started. My name is Mr. Rankin , or Mimic if you'd rather call me that. My class is to help each of you develop your respective powers and aliases. What you do with my training once you leave the school is up to you. Now, I want all of you to state your real name, desired alias, and why you chose that alias."

Ben 
Ben walks in right as Mimic finishes his question and answers, "Ben Parker. Thanatos. Simply put, I finish what I start."

Anthony

Anthony shrugs and speaks with a confident voice as eyes return to their normal hue, "My name is Anthony Luthor, and if I must pick a moniker, I chose Domitor. It's a Latin word that can mean either tamer or vanquisher. If I can't tame my rivals and enemies, then I'll vanquish them."
