The Hyper Beam(ハイパービームHaipā Bīmu) was first officially introduced in Super Metroid. The Hyper Beam is a special and incredibly powerful beam. The beam itself is a long line of shifting rainbow colors. Samus Aran acquired the Hyper Beam when she was losing in her final showdown against the Mother Brain. Her baby attacked Mother Brain and drained from her the energy used to fire the Laser Brain Attack, giving it to Samus as it replenished her Energy Tanks. Mother Brain killed it, and it exploded over Samus, channeling the energy through its remains into her Power Suit, which presumably created the Hyper Beam. Samus used the Hyper Beam's immense power to overpower and defeat Mother Brain once and for all.
