The Interception Tilt Rotor Spectre (Specter in some localizations) is the Grand Canyon boss from Strikers 1945 III.
In Battle Edit
Specter appears as a helicopter form with two sets of propellers. He can fly around to battle the player. When you defeat this form, he will transform into a stag beetle. Watch out for the bullets and then he reveals the blue orb. When the blue orb disappears, he continues to battle with the player, spinning his body in a corkscrew motion. He then fires a barrage of bullets while spinning. First, you will try to avoid the bullets when damaging Specter. When you defeated Spectre, he explodes and you earn money or rubies.
