Gordon Freeman

A young scientist and main character from the Half-life series.

MIT Diploma
A young scientist convinced to join a science facility by his MIT teacher, he was the wrong person at the right time.

Gordon Freeman had been for around a month working his way up in Black Mesa by putting his MIT diploma to use pushing boxes around, when an experiment goes wrong and begins the Resonance Cascade, aliens invade Earth in the Black Mesa facility sending it into chaos. Freeman does his best to survive not only the aliens, but the Government Agents, Army and Black Ops sent to wipe out the facility and dispose of everything, including him. While he does this, a well-dressed entity picks a certain interest in him while watching from afar. As this nerd scientist makes his way through impossible situations in a chaotic giant secret facility, he understand that more is at risk that his own life, and ultimately teleports to the alien planet believed to be the source keeping the dimensional rift open, where Freeman defeats the Nihilanth. Unbeknownst to him, this would allow the Combine to invade. Freeman is then contacted by the G-Man, whose employers are interested in him, making Gordon an employment "offer" which he grittily accepts.

Several years later, he would be waken up by the G-Man to work for him, putting him in the right place at the right time, where he discovers the Combine have invaded Earth and enslaved the Human race.

And what's more, the Combine are actually a force of Wrestling companies and by "enslaving" it means gluing them to the TV as not to miss the amazing fights that only happen on the TFR ring.

Season 2
What important detail that the government agencies don't know, is that Gordon Freeman was prepared to face the oncoming danger by being a freelance wrestler in his university days.
