The Uri Bomb (瓜ボム, Uri Bomu) is an attack where Gokudera uses Uri as a bomb, using Uri's tail as the fuse. However, this attack can only be used twice in a period of three days, as it consumes Uri's own Flames rather than the user's. The more it is used, the smaller Uri gets. When he regains his strength, he returns to normal size. The explosion generated from the blast is strong enough to burst a Fiamma Balloon.
