The Magic Capsule B (魔法のカプセルB Mahou no Kapuseru B) is an item from Alex Kidd in Miracle World. When used, a barrier appears around Alex Kidd to protect him from harm. Similar to the Teleport Powder, Alex will be temporarily invincible, except for spikes and similar hazards, but he can't punch while the barrier is active. Only two are available in the game, both sold in Shops for 120 Baum. The first is in the Bingoo Lowland, where it can protect Alex from the lightnings, and the second is in the City of Radaxian.
