Found in Metroid II: Return of Samus and essentially the precursor to the Energy Charges from subsequent games, the Big Energy Ball replenishes Samus' entire energy store upon contact. However, unlike the aforementioned Energy Charges, these large shimmering energy balls are usually found in remote locations within the regular playable field, hidden in every area except Phase 5 and Phase 8. In Phase 1, Samus Aran's Gunship contains a Missile Battery and a Big Energy Ball.
Currently, Metroid II: Return of Samus is the only game to feature this item. Its remake, Metroid: Samus Returns, replaces them with Energy Recharge Stations, although the Big Aeion Orbs seen throughout SR388 are quite similar.
