The Spy

The Spy is the deadliest, and yet at the same time most vulnerable class in Team Fortress 2. He relies on his ability to Cloak to be able to infiltrate enemy lines and escape when needed, and uses his Knife to secure instant kills from behind. The ability to score instant kills and without the enemy reacting and fighting back is a cause of annoyance to some players, especially those playing easily stabbable targets (such as the Heavy or Sniper).

Background
The Spy has no truly discernable background, but using information we already have (voice clips etc) we can make an educated guess that he is French. Despite his French accent, he can also speak a range of European which hint towards other ethnicities. He will occasionally say words such as "Prego", which is Italian for "You're welcome".

The Spy had an apparent relationship with the Scout's mother, however whether they are still together or not is unknown. Some people believe that the Spy's worst enemy, the Pyro is actually the Scout's mother, but there is no actual proof for it. A picture of his beloved is engraved onto his unlockable pistol, the Ambassador.
