This is a plane from MetalStorm: Online.
This plane resembles an F-22 Raptor. It is an agility class plane and is thus best suited for Dogfights where turning toface your enemy is essential
The F-22 is a stealth fighter, meaning unable to be detected by radar, making it virtually invisible to the enemy at long range.
In-universe, the Thresher appears to be a sister plane of the F-106 Arbiter, which fulfills a similar role.
