The G-Man

"'My... motives are not necessary, Dr. Smith. What, is, necessary, is that you fulfill your end of the... agreement, hm?'" The G-Man is an enigmatic figure. Nothing is really known about who he is, his goals, or why he does what he does. All that is known is some of his abilities, and that he knows something everyone else doesn't. He is shown to have no particular side, stepping in to help whoever whenever, although likely for his own benefit and not out of any form of generosity.

Appearance
The G-Man has black hair with a widow's peak, luminous green eyes and pale white skin. He always wears a grey-blue suit with purple tie and black shoes. He carries a briefcase in his right hand. His face is wrinkled. Strangely enough, his suit always appears neat and clean, almost as if it was just made merely minutes ago.

Personality
The G-Man is a complete enigma. He has a calm, almost uninterested and uncaring demeanour. He'll often be seen straightening his tie or brushing his suit, even if the situation around him is hectic and anarchistic. He is rarely agitated - but if he ever becomes so, he maintains his calm personality, albeit with a fair bit of strain. He has also demonstrated a sense of humour, even if very dry."'...I see that he is not... alone, hm? A... companion.'"He does seem to care about the well-being of others, though whether or not this is genuine is unknown. He seems disappointed - even concerned - at Dr. John Smith's drinking and smoking habits, stating that "It would be a shame, if [he] let [his] work go alongside [himself]". He demonstrates some form of compassion during the Resonance Cascade, offering to resurrect Smith, and later offering to ressurect Chloe Aines during the visit to Revdenstam Hospital.

Visits to Dr. Smith
The G-Man has made frequent visits to Dr. John Smith. These would typically involve him chastising Smith about his alcoholism, stating numerous times that his 'employers' want Smith in good condition. He also has mentioned that after his 'work' is complete, "[he] will be... rewarded" by either the G-Man himself, or by his employers. During these visits, he would also interact with Mia, stating his employer's gratitudes for "keeping, Dr. Smith... alive." and informing her that he had been authorised to "nudge things in a certain direction" to her liking. Whilst she did not initially accept, later this offer proved useful.

Reviving Dr. Smith
After Dr. Smith tragically passed away in the Resonance Cascade, the G-Man appeared to Mia again, this time with the added effect of time slowing to a crawl. He offered again to "nudge things", to which Mia accepted, asking for the whole event to be prevented. The G-Man informed her that this could not be done, but that he could instead bring back Smith."Mia: 'I want this to be prevented from happening..!'"

"G-Man: 'That... would be a considerably large nudge, wouldn't you... agree? Perhaps, I could... offer, you... something else.'"When she accepted his offer, he took her to a mysterious alternative dimension, which seemed to be a twisted version of the Central District. He pointed to a green outline of where Smith had been, before instructing Mia to "Take, his soul. And... return it, to his body". When she did so, the world returned to normal and Smith was revived. Afterwards, the G-Man departed, stating he looked forward to "when [they] may co-operate again."

Revdenstam Hospital
At the times of Monty Doe 's abduction of Jessica Aines, her sister, Chloe Aines, sacrificed herself to defeat an overwhelming swarm of zombies, Alien Grunts, and Xen Controllers. Whilst Kotoko Ririko, Thomas Capaltant and "Zeke" mourned her death, the G-Man appeared to Kotoko, stating that his employers had an interest in both Kotoko and Chloe. He offered Kotoko a similar deal to Mia, which she accepted. Before he returned everything to normality, he told Chloe to tell Dr. John Smith to "prepare for unforseen consequences.".

Employing Kaitlyn Rose
After Dr. Vormitz, Kotoko, and Dr. Smith conspired to deal with Kaitlyn Rose, the G-Man showed up once again, this time to offer something to Kaitlyn."'This... person... Miss Soleil Smith. She means, something to you, yes. We have... established this. If you do, a few favours, hm? Then, I can offer you... a future, with her, perhaps.'"Kaitlyn accepted his offer, to which the G-Man was delighted. He informed Kaitlyn that he would "see [her] up ahead", alongside informing her that her first task will be briefed to her soon.

Kotoko Ririko
It was evident at this point that the G-Man had also taken interest in Kotoko. He began appearing to her - twice on prompt of her shooting herself, and once unprompted. During the prompted events, he was lured into the TARDIS by Kotoko killing herself - mainly so Thomas could figure out what he wanted from everyone. The G-Man was initially held off by "Zeke" and the TARDIS, causing him to be irritated and break his normally calm demeanour."'We'll, see... about that.'"After learning this, Kotoko was revived and Thomas told "Zeke" to leave, before trying again. This time, the G-Man was able to discuss his displeasures at her death, both from him and his "employers", stating Kotoko was a possible valuable employee. He later appeared to her on his own, informing her that the assignment that Mia had been given was to now be passed onto her, before giving her an ominous warning and leaving."'あなたが失敗した場合...あなたは苦しむでしょう. '"

Key Events - Rapture [Post-Reset]
The G-Man has yet to make his presence fully known, however he will occasionally appear in areas with large crowding, so as to not be noticed.

People aware of the G-Man

 * Dr. John Smith - The G-Man frequently talks to him, and it's almost certain that Smith is under his employment.
 * Mia - After accidentally interrupting one of his visits, the G-Man has taken an interest in Mia and her abnormal abilities.
 * Dr. Phoenix Vormitz - The G-Man has interacted with Vormitz, enquiring about the production of some unnamed projects.
 * Kotoko Ririko - The G-Man offered Kotoko a similar deal that he offered Mia - but this time, to resurrect Chloe Aines.
 * Soleil Smith - Though indirectly, Soleil is semi-aware of the G-Man, though not by appearance or name. However, she has seen his briefcase and piercing glare through visions by a sword she purchased from Rouxls Kaard.
 * Kaitlyn Rose - Feeling a watchful presence since Revdenstam, and having been told of a briefcase and piercing blue eyes by Soleil Smith, Kaitlyn would later become an employee for The G-Man, placing her in stasis in between jobs.
 * Thomas Capaltant - Whilst the G-Man has never talked to Thomas, the duo are very aware of each other.

Trivia

 * The G-Man speaks in a stunted way, almost as if he were an alien attempting to speak English for the first time. He makes long pauses between certain words, sometimes halting whilst essentially searching for the correct word.
 * The G-Man and his presence is a direct reference to the Half-Life franchise, alongside the Resonance Cascade.
 * It's entirely possible that Vormitz is, or was, under the G-Man's employment.
