armageddon bomb

Lit. "Planet Destruction Bomb"

A "gadget" from Doraemon. Essentially an atomic bomb that Doraemon occasionally brings out when he went mad or insane (especially when he saw a rat). Primarily served as a comic relief within the series.

Due to the nature that the bomb occasionally appeared, it's never explained why Doraemon possess such a weapon, despite he is supposed to be a "baby-walker robot". The bomb is also never used in a more "serious" situations (such as a life-threatening moments in various Doraemon movies), mainly due to the kid-oriented theme of the series.
