Magnetic Shockwave

Magnetic Shockwave (マグネティックショックウェーブ) is one of Magneto and Onslaught's special moves in the Marvel vs. Capcom series, which creates several shockwaves. Mega Man gains this attack in his ending from Marvel vs. Capcom: Clash of Super Heroes after defeating Onslaught. During the ending, he picks up a Special Weapon Item and moves to a "Get Weapon" screen with Mega Man 3's music playing as it shows him using the attack.

In the PlayStation version of the game, Magnetic Shockwave can be used by Mega Man as a Hyper Combo after completing Arcade Mode with him and then holding down the Select button while selecting him.

Trivia

 * Magnetic Shockwave is the second Special Weapon gained from a final boss, the first being the unnamed missile from Wily Machine II.
