地球破壊爆弾 地球はかいばくだん
Lit. "Planet Destruction Bomb"

A "gadget" from [[Doraemon]]. Essentially an [[nuclear weapon|atomic bomb]] that [[Doraemon (character)|]] occasionally brings out when he goes mad or insane (especially when he sees a [[rat]]). Primarily serves as comic relief within the series.

Since the bomb only rarely appears, it's never explained why Doraemon possesses such a weapon despite that fact that he is supposed to be a "babysitting robot". The bomb is also never used in any more serious situations (such as life-threatening moments in the various Doraemon movies), mainly due to the kid-oriented theme of the series.

On Danbooru, the bomb is tagged as a [[nuclear weapon]], because when "the manga chapter":[http://doraemon.wikia.com/wiki/Chapter_115:Mouse_And_Bomb] was first serialized in 1974, the gadget was actually called a nuclear bomb.
