Thomas "Tom" Banachek is the head of Sector Seven's Advanced Research Division (and pretty much all of S7's current doings).
Transformers (2007) film
Actor: Michael O'Neill
Banachek was sent to the Pentagon to brief Defense Secretary Keller by order of the President of the United States (who was busy purging Ding Dongs). Banachek showed Keller classified footage that was deemed "beyond Top Secret". The footage showed that the Mars Beagle 2 Rover, previously believed to be lost in descent, in fact survived its landing and had recorded thirteen seconds of footage before a mysterious creature destroyed it. Banachek then showed a comparison between the Martian and the "weapons platform" that attacked the SOCCENT base in Qatar, concluding they were of the same design. Taking Secretary Keller to Hoover Dam, Banachek also met with Sam Witwicky and Mikaela Banes.
While Sam was unwilling to talk to the agents over Bumblebee's imprisonment and treatment, Banachek pointed out that lives were at stake and that they could negotiate, prompting Sam to demand that Bumblebee be released, his parents be brought there, and Mikaela's criminal record be cleared.
When the teenagers, Keller, Maggie Madsen and Glen Whitmann were taken to see the "Iceman", Banachek explained that Sam's great-great grandfather had found him, and that the military had not been informed because there was no credible threat verification. He admits to Sam that he admired Captain Witwicky for making one of the most significant discoveries in the history of mankind. This prompted Sam to inform them that the Iceman, Megatron, was the harbinger of doom. When the power started to fail after Starscream's attack, the soldiers headed to the armory. After Captain Lennox forced Simmons to listen to Sam's request to release Bumblebee by holding him at gunpoint, Banachek called for calm.
Tom Banachek's status after Sector Seven was terminated is unknown.
In an alternate timeline, Megatron killed Sam, took the All Spark and conquered the United States of America. Banachek became part of the resistance alongside Mikaela and the Autobots. When Bumblebee & Mikaela tried to thaw out and free Optimus Prime from the former Sector 7 base, Banachek provided them with data via radio contact to achieve their goal. He guided Mikaela to the room where Sector Seven's greatest weapon, a nanovirus targeting All Spark frequencies, was kept.
In the aftermath of the Autobot victory, Banachek has become a member of the new US government, under new President (formerly VP) Allen. He tried to convince Allen to open communications with the Autobots. He was ignored.He is still in constant contact with Mikaela.
Tom now runs a reformed Sector 7, and is currently trying to stop everyone realising Earth is dying.
