He was the son of Athanasios Vlachavas. In the 19th century, he achieved a prominent position among the other klepht leaders, and led the fight against Ali Pasha, the powerful and semi-independent Ottoman governor of Yanina. Along with others, he prepared a large-scale anti-Ottoman uprising in May 1808, but it was betrayed. Vlachavas was later captured by Ali Pasha by ploy, executed and quartered.

A statue of Thymios Vlachavas has been erected near the former Ypapantis Monastery at Meteora in Thessaly, Greece.
