An Enterprise lieutenant who served at navigation during the pursuit of the Gorn ship and at the helm during the crisis at Eminiar VII, both in 2267.
Lieutenant DePaul is a bridge officer seen in two first-season episodes. In Arena he sits at navigation as the Enterprise chases the Gorn vessel from Cestus III at ever higher warp speeds, until both ships are stopped dead by the Metrons.
In A Taste of Armageddon he is at the helm while Scott holds command. He reports the fusion attack that Eminiar's computers register against the ship and carries out Scott's orders as the engineer refuses to lower the screens for Ambassador Fox and pulls the ship out of range of the planet's disruptors.
DePaul was played by Sean Kenney, who also portrayed the scarred and paralysed Christopher Pike in The Menagerie.
