Bombs are the basic weapons for Samus Aran's Morph Ball. Bombs can break certain objects, and are essential to defeat many bosses such as the Generator Guard Drone II and the AT-BT, although they are not very effective on normal enemies. Bombs can damage enemies within a certain range. Bombs have appeared in every Metroid game. In Lego Metroid, bombs have a small role in helping Samus venture through her mission. Bombs are capable of destroying black-lined bricks to open new paths. Samus acquires the Morph Ball Bombs by defeating the T-Gunner in the Junkyard.
