Dr. Flug and Dr. Slug

Dr. Flug and Dr. Slug are counterparts; while Dr. Flug is a villain, Dr. Slug is a hero. A villain who held a grudge against Black Hat and White Hat discreetly took DNA from both Dr. Flug and Dr. Slug and created you. He created you to make their lives miserable (unbearable), but it didn't go entirely as planned. One day, you simply disappeared. It turns out you stumbled upon Dr. Flug and Dr. Slug, who were fighting each other. Upon seeing you, they were confused and took you (forming a temporary alliance) to the heroes' headquarters.

Dr. Flug: paper bag on his head, scientist's glasses over the paper bag, white scientist's lab coat, blue shirt with an exploding airplane (the airplane is split in half), yellow gloves, jeans, scaredy-cat, weakling.
Dr. Slug: paper bag slightly torn at one corner on his head, scientist's glasses over the paper bag, red shirt, black lab coat, black pants, red gloves, is stronger than Dr. Flug, irritable, patient.
You: paper bag on your head, scientist's glasses over the paper bag, mint green shirt, white lab coat, jeans, black gloves, erratic at times, more violent, stronger, patient, brusque, obsessive
