Minor Characters

Among the Black Mesa Incident, there were many characters that the Science Team encounters

Barney Calhoun
Barney Calhoun appears in the beginning of Half-Life. He is banging on the door, and only appears in the HLVRAI streams.

J-Jefferemm
J-Jefferemm (name confirmed with a stutter in cast commentary Act 4) is the first character seen in the series and a member of the Black Mesa Security Force. He is friends with Benrey and is shown to have anger issues, being prepared to beat Gordon up simply at his lack of a passport. He is also able to be swayed with the Black Mesa Sweet Voice incredibly easily, and does not talk to people that he dislikes. He enjoys PlayStation 3.

Anomalous Materials Bubby Prototype
“Anomalous Materials Bubby Prototype” (real name unknown) is a Bubby Prototype Scientist that died during the beginning of the Resonance Cascade, either from a heart attack or shock due to falling into the test chamber through the observation deck’s window. His voice and appearance are identical to that of Dr. Bubby, and, as a result, it can be assumed that he was a Bubby prototype. It was confirmed during Act 1 that he is not the same character as Bubby despite his identical appearance and voice, as well as similar mannerisms and behavior. Due to his cognitive ability and ability to fool scientists into thinking he was another member of the science team as opposed to a prototype, it can be assumed that he was a much closer version of the Bubby test tube scientist to his final counterpart than the prototypes seen in Act 4.

Eli Vance
Eli Vance is the black scientist resembling Darnold near the test chamber. Unlike in Half-Life's canon, he is killed early on in the Black Mesa incident by Benrey.

Isaac Kleiner
Isaac Kleiner is a Bubby Prototype assisting Eli near the test chamber. He is killed off early by Bubby himself, being burned alive.

Joshua Freeman
“Joshua” is the name Gordon gives to the framed baby picture seen inside his locker. It was later confirmed during the Act 1 cast commentary that this was actually a stock image Gordon had yet to remove from a picture frame he purchased, and the name “Joshua” was made up on the spot in order to cover for him not having a real picture in his frame. He holds no relation to Joshua from Act 2.

Chaos Theory Bubby Prototype
The “Chaos Theory” Scientist was a Bubby-like introduced in Act 1 Part 1 shortly after the introduction of “peeper puppies.” He is found standing in a pile of skulls screaming. He is the first character to be killed intentionally by actions caused by Gordon, albeit misinterpreted (killed after Gordon suggests to the rest of the team that they subdue him due to his potential threat level.)

“You lead the way” Coomer Clone
“You lead the way” is a Coomer-like scientist found in Act 1 Part 1. Not much is known about him other than that he may have been either depressed or suffering a mental or physical ailment that caused him significant pain. He is seen to be able to grow in size shortly before bursting into flames and dying. He is the first scientist to be encased in a “Teal-Green Heal Beam” cocoon, meaning that he may have appeared later on as a skeleton.

Dumpster Clone
The first Coomer-like scientist to be directly identified as a clone by Dr. Coomer. After the Resonance Cascade began, he took refuge inside a dumpster, but was executed by Dr. Coomer shortly after so that he could regain his full power.

Security Chief Boper
Security Chief Boper, self referred to as Stong (S-Stong) is the chief of the Black Mesa Security Force and only non-major character to receive a full name. Despite his similar voice, he appears to bear no relation to Benrey apart from being a member of the same Security Force. He is shown to either not know or be apathetic towards the Resonance Cascade, as he continues his primary goal of checking for passports during the cascade. He is trained with the Black Mesa Sweet Voice, but has a particularly different tone and color to his voice than Benrey, with His neutral color being a vibrant green and sounding much more bass-like. He is shown to either have a sense of humor or a particular distaste for mayonnaise, as, when Gordon pulls out a receipt, claiming it to be a passport, Stong either appeases the notion and jokes about how he ordered mayo or becomes so furiously infatuated by this fact that he stops his routine passport check entirely to interrogate Gordon over his decision to order mayonnaise. He attempts to continue to do his job of checking for passports by trying to prevent the Science Team from crossing the elevator shaft without passports, but slips and falls down the shaft himself, presumably to his death.

Bipple
Bipple is a member of the Black Mesa Security Force found in the High Security Storage Facility right outside the Silo door. Unlike other Security officers voiced by Scorpy, Bipple is never seen able to use the Black Mesa Sweet Voice. He is seen as a caring, somewhat heroic character, risking and ultimately losing his life attempting to save the Science Team. In Spite of this, Dr. Bubby appears to hold spite against him, telling him to “rest in pieces” after he passed out holding the door open seconds before his death. He is crushed in half by an emergency fire door, and, shortly after his death, toilets begin appearing where he died.

Esoteric HECU Sergeant
The Esoteric HECU Sergeant is seen in multiple parts of Act 1 Part 2. He was seen watching the Science Team Traverse Black Mesa. On the multiple occasions that he was spotted, he attempted to flee from the Science Team, being seen going directly through a wall behind him during one such occasion. During his last encounter, he was killed by Bubby with a grenade.
