- Description, Angry Birds (game)

In the original Angry Birds, Shockwave is a power-up that is first introduced in Tutorial 0-13 (originally in Short Fuse 26-1). He can also be used in any other level in the game as long as the player has one. Shockwave can be obtained by buying him in the shop or by random chance at The Mighty League and gifts.

When using Shockwave in a gameplay, the current bird will hop off the slingshot to give way to Shockwave. Shockwave has the same strength as Bomb. In addition, when the player taps the screen or Shockwave collides with an obstacle, he will proceed to unleash a growing circle of electricity that will slightly push away the objects and electrocute the enemies it touches. After this, Shockwave will disappear.
