Carlos was a freelance weapons manufacturer and terrorist. The character appeared in the 2006 James Bond film Casino Royale, portrayed by Claudio Santamaria and was later seen in the 2008 video-game 007: Quantum of Solace.
The terrorist financier Le Chiffre uses a Ugandan warlord's money to short-sell stock in Skyfleet, a promising aerospace company, thus betting the money on the company's failure. After his original bomb-maker is killed by James Bond in Madagascar, Carlos is hired to destroy the company's Skyfleet S570 prototype.
Chase in Miami
After 007 has killed his boss Alex Dimitrios, the spy notices that the ticket has disappeared and that the bag that was stored in the cloakroom under that ticket has gone. Running outside to be confronted by the mass of people, Bond uses quick thinking to call the person using Dimitrios' phone, since he had sent a text to him already. After identifying the target, Bond follows Carlos to Miami International airport.
At the airport, Bond follows the terrorist who changes into a police uniform. He enters a restricted area just before Bond can stop the entry door from closing. Thinking about it for a few moments, Bond gets an idea that the text sent to Mollakamight spell out the numbers to use on the keypad. Luckily, Bond's guess is right and he makes a hurried pursuit.
In order to distract security staff and remain unchallenged, Carlos activates the sprinkler system as a diversion, and walks out onto the runway. He commandeers a fuel truck and before heading off towards the Skyfleet S570prototype, attaches a small keyring bomb to the underside of the tanker. Bond pursues Carlos on foot, managing to run up some aircraft stairs and jumps on top of the tanker. Carlos tries to dislodge Bond by running the tanker into all sorts of aircraft vehicles, while he tries to get Carlos out of the cabin. As the tanker approaches the Skyfleet S570 prototype, Carlos jumps from the tanker leaving Bond to stop the tanker just before it hits the plane. After Bond is arrested by security services, Carlos smugly starts to detonate his bomb. During the fight however Bond had removed the bomb from the tanker, placing it on Carlos' belt. He realises this too late when he is killed by his own bomb.
During the course of the 2008 video-game 007: Quantum of Solace, Bond opens up to Camille Montes about the death of his former love, recounting the events of Casino Royale. The player follows through the plot of Casino Royale, with Bond infiltrating the Science Center to kill Dimitrios and eventually saving Skyfleet from Carlos and an army of terrorists who have hijacked Miami International Airport. The level concludes with a pitched battle inside the S570's hangar. In an introductory cut-scene the character is identified as Carlos Decameron, an unemployed American electrical engineer and a suspected arsonist and weapons manufacturer.
