Mega Man Zero 2

Mega Man Zero 2 (known in Japan as Rockman Zero 2​ (ロックマンゼロ2)), is an action platform game developed by Inti Creates and published by Capcom for the GBA in 2003. It is part of the series, a sub-series of the  series created by Keiji Inafune. It is the sequel to Mega Man Zero, and was succeeded by Mega Man Zero 3. The game was re-released as part of the Mega Man Zero Collection for the Nintendo DS, with new and improved sound quality, and contributes toward an in-game wallpaper and Mod Card collection. Some content has also been edited from the original Japanese release for the sake of maintaining an E rating with the ESRB.

The initial releases of the game installments contain death animations where bosses spurt out a dark red oil when they are slain, resembling blood. In the Mega Man Zero Collection, uses of the words "die", "death," and "kill" have been stealthily replaced with softer dialogue. The collection also updates in-game mechanics, with new controls and menu interfaces utilizing the Touch Screen of the Nintendo DS. All sound effects and music tracks in the collection are noticeably cleaner, remastered to fully exploit the DS's enhanced digital audio range compared to the Game Boy Advance. Aside from some minor changes in game play, it retains the original formula of Mega Man, but reintroduces the primary feature to gain abilities from enemy bosses, notably missing from the preceding installment of the series.

Story
The sequel to the first title continues one year after Zero began his continuous attack on the immeasurable number of Pantheons seen at the end of the first game. This began after discovering his old friend, Mega Man X, has turned into a weary Cyber-Elf, and dealing with a would-be imitation known as Copy X. At the original X's request, Zero continues to fight. Meanwhile, an auspicious Reploid known as Elpizo has discovered Neo Arcadia's true motives and has abandoned his job within the capital for the sake of fighting back with a strike force of his own, feeling vengeful at its government for sacrificing the well being of innocent Reploids out of fear they will harm the human population. However, he is too haughty and self-absorbed to fully recognize the true might of Neo Arcadia, and his rebellious actions eventually lead to the discovery of a frightening entity with a haunting legacy of destruction. If left undeterred, history may be doomed to repeat itself, and once again, the whole world will be put in jeopardy. Elsewhere, a mysterious man watches these events unfold, knowing they will help incite a master plan of his own...
