Luke Smith

An artificial human, the Archetype was the creation of the Bane. He had the physical form of a teenager upon his creation, despite his actual age being much younger. On the day of his "birth" he met Maria Jackson, from whom he also began to learn how to speak. He helped defeat the invasion plan of his creators. He was named "Luke Smith" after being adopted by Sarah Jane Smith.

The Bane's invasion of Earth depended on getting as many people as possible under their control. Their strategy was to use a Bane secretion as an ingredient in the drink Bubble Shock!, but approximately 2% of the human population was immune to the effect.

In order to get the last remaining 2% to accept Bubble Shock!'s "special ingredient", they created the Archetype from thousands of samples of various entrants to the Bubble Shock! tour, including Maria Jackson and Kelsey Hooper. However, when Kelsey inadvertently set off an alarm by using her Mobile phone, the ensuing events caused the Archetype to awaken and escape. He joined Maria and Sarah Jane, instantly befriending them. Later, he effortlessly memorised the signal to "call" the Bane with the Star Poet's phone, which destroyed the Bane Mother along with the Bubble Shock! factory.
