Timebombs are one of the original BrickBattle weapons. They will drop on the player's head, if the player isn't moving, and after a few seconds, they blow up, killing anyone near it. In order to dodge it, players must simply walk away from it, roll it away with superballs, or, alternatively, due to a physics glitch, the player can jump over it several times and "kick" it a long distance.
The original timebomb had a much longer fuse and could be dropped at a faster rate than the timebomb as seen in the tool bar. Some of ROBLOX's older places still use the old timebomb.
