Capsules are small containers in Super Smash Flash 2 that were first introduced in Super Smash Bros. for Nintendo 64. They are similar to crates and barrels, but they are smaller and only contain one item. When attacked or thrown, they usually release an item, and if one enemy is hit, it will take 8% damage, but there is a 1-in-8 chance that they will explode instead and deals 24% damage. However, the capsule will never release a crate, barrel or another capsule.
