Alexis (Alexa, last name not given), befriended her best friends Rad and Carlos when they activated the first of many dormant Mini-Cons on Earth, the Street Action Team, as Megatron and Optimus Prime's forces arrived on Earth. This led to their alliance with Optimus and the Autobots, as they frequently helped them on missions, teaching them the ways of Earth. Unfortunately, they were unable to keep their friendship with the Autobots a secret from the local bullies, Billy and Fred (Jim), but the two boys quickly softened and became friends with the trio, as they too became Autobot allies. An encounter with Sideways in cyberspace gave the kids their first glimpse of the world-devourer Unicron.
