Mother Computer Z (マザーコンピュータZ Mazā Konpyūta Z?) is the final boss in the Game Boy version of Nemesis. As its name states, it is the central computer of the Bacterian fleet in this game.

Attack patterns

Mother Computer Z, unlike the Xaerous Brain in Gradius, won't go down without a fight. Similar to gunwalls, this final enemy fires a lot of bullets and generates enemies from the top and bottom.


There's one easy way to defeat this boss that can be exploited as soon as it appears. If the player has a Shield equipped, ramming into the boss will instantly defeat it.
