Romulan warbird commanded by Commander Donatra, which came to the aid of the Enterprise-E against Shinzon's Scimitar.
The Valdore was a Romulan warbird of the Valdore type, a sleek green design with broad wings, commanded by Commander Donatra in the days after Shinzon seized power on Romulus.
In Star Trek: Nemesis, Donatra brought the Valdore and a second warbird to aid the Enterprise-E against Shinzon's Scimitar in the Bassen Rift, showing that not all of the Romulan military backed the Reman coup. Both Romulan ships were quickly disabled by the Scimitar, but Donatra's gesture was a hopeful step toward friendship between the Romulans and the Federation.
