The Lethal Bob-omb is a powerful variety of a Bob-omb found in the cellar of Shroob Castle in Mario & Luigi: Partners in Time. A Lethal Bob-omb's fuse is always lit, meaning once it touches someone, it explodes. Additionally, they are constantly flashing, wear purple shoes (like Rob-ombs), and move more quickly than Bob-ombs.
In battle, Lethal Bob-ombs attack by approaching the Baby Mario Bros., then running back and forth in front of them. Eventually, it chooses a Baby Bro. to attack and rams into him, self-destructing and causing damage. The Baby Mario Bros. can counter this attack with their Hammers.
