His most prominent appearance prior to Duke Nukem Forever being released was in Duke Nukem: Advance and his role in this game was probably inspired by his planned role during 3D Realms ongoing development of Duke Nukem Forever; Duke Nukem Advance was the first game to be released where he was given a larger role.
In the 1999 build of Duke Nukem Forever he was probably a commander of Earth Defense Forces (EDF). The General is also in the final version of Duke Nukem Forever, where he is voiced by Bruce DuBose and he also appears in the Doctor Who Cloned me DLC. Another game he features in is Duke Nukem: Critical Mass.
Graves was the man who taught Duke Nukem everything he knows and was his trainer when Duke was in the U.S Army. A good point of this is in Duke Nukem Forever a picture of Duke Nukem in U.S Army Gear is seen in Duke Nukem's Lady Killer Casino.
Also Graves admires and knows Duke better than anyone else and Duke is Graves' number 1 choice when all else fails.
Duke Nukem 3D: Atomic EditionEdit
General Graves makes his first appearance in the intro of the fourth and final episode, "The Birth". He is seen showing Duke the footage of aliens breeding the human-alien hybrid, Alien Queen, and sending him on a new mission to destroy it despite Duke's current vacation after killing Cycloid Emperor.
In this instance General Graves is voiced by Jon St. John.
Duke Nukem ForeverEdit
In Duke Nukem Forever, the General wears a blue uniform, in contrast to the green one he wear in past games. General Graves and the President both contact Duke in the Duke Cave about the new alien presence. At first, Graves agrees with the President that the aliens may be peaceful, but they quickly prove him to be wrong. Throughout the game, Graves turns down the President's orders and engage hostile aliens in battle with the EDF forces. Graves sends Duke on two missions: save the chicks from the Duke Dome, and later put an end to the invasion in Hoover Dam. General Graves personally appear to give Duke the orders in Lady Killer casino, and later saves him after the Cycloid Emperor is killed.
In this game he has a dark rectangle under his right eye. This is similar in placement and size to the bar codes seen under the eyes of EDF soldiers in some earlier versions of the game's development. The significance of this mark remains a mystery.
Duke Nukem AdvanceEdit
He was Duke's commander in Duke Nukem Advance, as he briefs and debriefs Duke throughout the game. In addition to giving Duke instructions he also commands soldiers in the Earth Defence Force. He often gives Duke Nukem advice throughout the levels and often states the best course of action in a specific situation; in particular he informed Duke Nukem about the shields surrounding the Alien Controller that he and the Earth Defence Forces were detecting; without being told that information it's most likely that Duke Nukem wouldn't have known about his weapons having no effect and would've been overrun due to Duke himself not possessing technology to detect the shields since General Graves and the Earth Defence Forces would have the necessary technology from their base of operations.
On occasion he can also intercept alien transmissions and analyze the area Duke Nukem is operating in and then pass the vital information on to Duke Nukem. Despite this there have been occasions where Duke Nukem has to tell the General about his current status as the General and the Earth Defence Forces will not always be aware of the situation Duke Nukem is currently in such as the temple about to collapse in Eygpt; in addition Duke Nukem sometimes has to find his own way to best deal with a situation; for instance though the General informed him about the Shields protecting the Alien Controller Duke Nukem was the one that thought about using the large crusher to defeat the Alien Controller.
Duke Nukem: Critical MassEdit
General Graves is, again, the mission commander. The game begins with the scene where Graves sends Duke into the future, to discover what strange menace claims the lives of his time-traveling agents.
- In an old 1999 trailer and screenshot for Duke Nukem Forever; the General in it also appears to be called General Graves.
- In the Duke Nukem "Balls of Steel" edition artbook it is revealed General Graves' first name is Phil. It also confirms this is meant as a pun on fill Graves as the general fills graves.
- Graves is also known to be married since he remarks that "Mrs Graves" will be happy to know he's alright.
