Paul Denton

Paul Denton is the elder brother of JC Denton. Like his brother, he also has nano-augmentations. He is the first character to try and convince JC to betray UNATCO. JC Denton is the clone of Paul, and they were born 11 years apart.

In Deus Ex, Paul starts as a seemingly pro-UNATCO character who appears rather frequently, giving JC his UNATCO mission objectives.

When JC reaches Hell's kitchen, for the first time he discovers that Paul has been issuing tear gas to the troops instead of ammo; to compound this strange behaviour, when JC returns to UNATCO HQ, he realises that Paul had failed the raid on the NSF warehouse and he is fired.

Further on in the game at Juan Lebedev's private hangar, JC finds out that Paul works for the NSF and the latter attempts to persuade JC to join, but UNATCO discovers Paul's treachery through JC's infolink, as Alex explains. MJ12/UNATCO activates Paul's killswitch which after a few hours renders him unable to move, so Paul returns to his apartment in Hell's kitchen and is forced to remain there in pain. The (former) UNATCO pilot, Jock, is told to take JC to Hell's kitchen, as Paul needs JC's Help. Once there, Paul tells JC to send a distress signal to the Silhouette member, Chad Dumier, and other NSF bases, in addition to pointing out that there is evidence of the conspiracy between UNATCO and MJ12 stored on a datacube nestled in the NSF HQ; when JC sends the signal, Walton Simons tells the troops to kill JC. When JC returns to the apartment to take Paul to Tracer Tong in Hong Kong to deactivate the killswitch, the MJ12 and UNATCO goons attack the apartment, which leads to Paul's death if JC escapes out the window; if, however, JC decides to stay at the apartment and fight his way out of the 'Ton, Paul won't die; in fact, he becomes invincible.

As JC moves through the MJ12 complex beneath UNATCO HQ, where he was held prisoner, he encounters Paul in the medical lab of the complex. Here, Paul tells JC about the explosive killswitch of mechanically-augmented soldiers like Anna Navarre and Gunther Hermann, which is activated by uttering a single phrase(killphrase). It is revealed that Smuggler helps Paul to get to Hong Kong.

When JC gets to Hong Kong and into Tong's base after destroying the Universal Constructor at Versalife, if you help Paul, you will encounter Paul sitting at a desk in Tong's lab, and he will say that he is recovering, but due to his present state, he cannot help JC.

Later on in the game, at Area 51, Paul communicates with JC through both the Infolink and the holocomm. In both cases, Paul encourages JC to trust his conscience and make his own choice as to who he should follow in the endgame.
