Sister of Colonel Nate Briar and cousin to the late General Michael Briar of the EDC. As a Briar, Alex has a knack for getting into trouble and an aptitude for machines. But she lacks the experience to fully use the skills due to her age. She is particularly drawn to the autobots and interacts with them any chance she gets. She shows no fear of even the most dangerous of stunts and throws herself into danger on an almost daily basis. Loves extreme sports, the more dangerous the better. Her closest friends call her 'Lexi' as she hates Alix or Alexandra calling them too girly for her tastes.
