Tynus was Commander Technician of the Q-base on Fosforon. He trained with Avon and later worked with him on a fraud. Avon was arrested but kept quiet about Tynus" involvement. On Fosforon Avon used this to blackmail him into acquiring a TP crystal from the A-line converter. Tynus stalled for as long as possible, sending a message to Servalan informing her of Avon's presence. Vila discovered the message. Tynus was eventually thrown into the A-line converter during a struggle with Avon, and died from the 250,000 volt current flowing through it (and him). He kept locusts, which he was seen sketching, and his colleague Dr Bellfriar suspected he might be "space happy".
