* AnticlimaxBoss: The final boss, which is the BigBad piloting a robot and two TOZ systems. She will use them to steal your weapon, but she isn't able to use the stolen weapon very well. If you have the G-Beam powered up at max, it shouldn't take long at all. Even better, if you have one of the game-breaking secret weapons, the boss won't even be able to copy it correctly and be stuck with Vulcan, making it even more of a cakewalk.
** However, if you don't have any special weapons or a shield, [[ThatOneBoss this boss will be quite tough]]...
* GameBreaker: A certain set of weapons, including the Tektite Blaster (T-Braster, similar to the Hunter from ''ThunderForce III'' except stronger), had unique conditions to acquire, some of which are seemingly arbitrary. They were only fired from the TOZ System, could not be leveled up, and were lost at the end of the stage (and you got the Vulcan back - at minimum power). These weapons make the [[DiscOneNuke Giga Beam (G-Beam)]] seem weak in comparison. They could also be obtained randomly in Stage 8.
* ThatOneBoss: The boss of the sixth stage, a HumongousMecha Amazon with a sword and shield. You could only hit her when her shield was down for a second. Furthermore, she had a SpreadShot consisting of three hard-to-avoid large projectiles, said attack was used when her shield was down, and the projectiles were NOT blockable with your TOZ system.
** The boss of the seventh level, which is the core of Gulfer's HQ. If you position your ship in the right place, NONE of its attacks will be able to hit your ship! Of course, this comes after the first 6 bosses, including that [[ThatOneBoss female gladiator robot]]...
