'Pilot' is the third main character of Romantically Apocalyptic. He is also one of the four original main characters, the others being Captain, Sniper, andEngineer. Out of all four, Pilot is the most mentally unstable one, subject to surreal fantasy and daydreams. It was revealed in a diary entry that he was once a fighter pilot.
The color associated with Pilot is green.
Pilot's obsessions include tormenting the Sniper and serving Captain. He often hallucinates, such as when he discovered a toy airplane and began to fly it around, imaginating himself as being in a terse dog-fight.
He is infatuated with Captain, and believes that Sniper wants to steal his leader from him. As such, he often devises ridiculous schemes to get rid of him, including a plot to feed him to a whale. When Pilot planned to found a "Church of Captain," he tried to convert Sniper, and was not pleased when he refused, tying him to a couch.
Snippy states in one of his journals that Pilot was once in the Army, which seems to be in keeping with his Green color motif, as Stalky, who was also in the army, has Green goggles before his 'transformation.'
Pilot also writes that he once had a "Blue Tiara", a headband civilians wore to access ANNET, but that his is broken. It still seems to get a weak signal from ANNET, and Pilot referrs to it as "A ticket to a one-way trip without a return policy," which suggests that he at least remembers it is dangerous. It is possible that Pilot's mental state is a direct result of him breaking his neural interface before ANNET was able to fully take over his mind during its' takeover.
Pilot seems to have a stuffed puffin toy, whom he calls Mr. Kittyhawk. He believes that Mr. Kittyhawk informed Cancer of his location, but this is almost certainly more of Pilot's inane fantasy.
A tag on his jacket says SG Christophorus Hatchenson, although whether this is truly his name is unknown - in fact, Pilot states that he might have killed the original owner and taken the jacket. Given his personality and mental state, this is far from unlikely.
SG could possibly be an incorrect abbreviation of "Seargent."
SG could also mean Star of Gallantry, a military decoration awarded to members of the Australian Defense force or other persons who have shown acts of great heroism or conspicuous gallantry in circumstances of great peril during action. Pilot's rank would not matter, as the SG can be awarded to any personnel.
If this is correct, it means Pilot could be Australian and has done something extremely heroic and brave in his past, or he killed such a person/found it on a dead body. It is possible that he was awarded the medal as a result of his flight to destroy Annet. If this is true, however, it must have been awarded before the mission began, as everyone would be too busy being dead to do so afterwards, unless the pilot did it himself, which, again, is far from unlikely, given his mentality.
A recent illustration has shown that pilot might be blonde, but this picture seems to be the work of a RA fan and not an official drawing of pilots real appearance.
This might perhaps contribute to understanding some of his mental instability a bit more; assuming he was relatively sane while he was in the Army. Pilot mentions in the diary entry that the "one million voices of Eureka still sing in my cranium. They ask me to stop... I know that they are all just dust now, and what has been done cannot be retracted." This refers to the fact that while wearing ANNET's headband or being in the range of one of her transmitter towers during his mission at Eureka, Pilot was actually able to perfectly hear the people he bombarded, which likely drove him insane.
The top panel in comic 62 might also refer to his discharge from the Army and his interactions with Captain, as he is holding either a picture of Captain or he is video-chatting with him. One picture refers to him possibly being arrested and later escaping his pursuers.
