Ingineer is one of the members of the TEEN FORTRESS 2. He is the smartest member of the group, and since he has passed the "time mashine exam", he is able to build a time machine that brings Marrissa Roberts to the future.
He has been frequently seen with Principal Business Man, who wrote the "time mashine exam" in question. Business Man also seeks counsel of Ingineer on other questions, such as the nature of Cave Jonson's experiments.
Among his other inventions is the syringe that grants one speshul powers. He uses it on Caroline, who passes the powers through her bloodline to Marrissa Roberts and Chell Junor Roberts. His evil clone also invents the syringe, and injects Cave Jonson with it.
