Doctor Isis

Doctor Henry Isis is a supervillain and one of Dick and Johnson's greatest enemies.

How Doctor Isis became a supervillain is, as of yet, unknown, but his first encounter with Dick and Johnson was also their first official mission as part of the government. As part of that mission, Dick, Johnson, and Tallulah Mae were sent to infiltrate a secret underwater base of Doctor Isis' and disable it. After having stolen a nuclear submarine, the three decided to destroy it from the outside instead. Doctor Isis was not only outraged by the destruction of his base, but also insulted by what he viewed as a violation of some code of honor, since the attack was carried out with no subtlety or much forethought. It was this insult that made Doctor Isis swear a personal vendetta against Dick and Johnson and view them as mortal enemies. It is assumed that this promise of vengeance also extended to include Tallulah, though her fate since the mission's success is unknown.

There are also other occasions on which Dick and Johnson have not only foiled Doctor Isis' plans of conquering the world, but incurred his everlasting animosity. In an all ought battle, Dick and Johnson both questioned his power and authority, as well as disagreed with him on the artistic value of country music, as the Doctor sees the genre as worthless.

Doctor Isis will typically send his ninja nurses to do his bidding. When fighting himself, he uses a wide variety of weapons, from RPG launchers to scalpels in close combat. His outfits typically resemble surgical scrubs. Isis appears to have a large network of secret bases all over the world, all of them well hidden in remote locations such as dormant volcanoes, underwater caves, and even one on Mars. Only through the Chief's agents are these hideouts uncovered and eliminated.

It is unknown whether "Isis" is Doctor Isis' legal name or an adopted moniker, but it has been confirmed to have no relation to the terror organization ISIS. In fact, the obvious connection that is often made is something Doctor Isis resents very much and has caused him to loathe the terrorist cell.
