The F-18 Hornet is a fairly average fighter. Its Snake Napalm is not particularly powerful. When deploying its special weapon, the F.A.E., the F-18 flies over the enemy and drops a bomb, then flies upside down in a loop to return to its normal position. The bomb does heavy damage to the enemy.
The F-18 is briefly seen in the intro to Sonic Wings 3 before the plane gets destroyed by Fata Morgana.
