* InvisibleAdvertising: There was no advertising for ''Blaster Master Overdrive''. [=WiiWare=] was not as promoted as a competent online service. The game was announced two months before the North American release, so almost no one has heard of it. People had to dig deep to even hear that this game even existed.
* KeepCirculatingTheTapes: ''Blaster Master Overdrive'' was a UsefulNotes/WiiWare exclusive, meaning that, if you didn’t purchase the game before the Wii Shop Channel was closed, the only way to play it now is through emulation.
* MarthDebutedInSmashBros: ''Blaster Master Zero'' uses plot elements from ''Metafight'', making it the first game released outside of Japan to use any form of ''Metafight'' continuity.
* NoExportForYou: ''Blaster Master 2'' was developed by UK-based Software Creations Ltd., and was only released in North America.
* SequelGap: There was a 10-year interim between the release of ''Blasting Again'' and ''Overdrive'', followed by a 7-year gap between ''Overdrive'' and ''Zero''.
* SerendipityWritesThePlot: Most boss rooms have the background flash and then blacken to pure black. This is done to use the background hardware to draw bosses too large for the sprite hardware to draw.
* WhatCouldHaveBeen:
** The NES game contains graphics pertaining to an ''eighth'' item, entitled Spike. If the littering of spikes around Area 8 does any part to indicate, this item was to protect the tank from them[[note]]Which, as players of ''Overdrive'' know, is exactly what the Super Tires do; it's believed this item was based upon it[[/note]]. The graphics for the item itself were repurposed as those of the Walls in ''Enemy Below''.
