The Scenario
Greater Sci-Fi combatant
They've stopped similar things before.
1. Metroid life drain. It's canon that nothing in the physical realm is lost (blood, ATP, etc.) and yet without it, the victim dies. It is known as "life energy" and is known to be mystical. Samus' shields block this, Space Pirate shields don't.
2. Gorea mind rape. Gorea is a psychic shapeshifter who successfully mindraped an entire species into killing themselves to feed him. He did this to multiple planets at once, while also draining their life. At one point he also sent a telepathic message to another galaxy. Samus' shields block this, including his TK.
3. Bryyonian Magic. It's confirmed that the Mogenar was a blend of technology and magic to create the perfect golem. Several of its attacks ignore matter. Samus' shield blocks them.
4 Chozo Ghosts. After the Chozo ascended to a higher plane of existence but were ripped back to the material world, they were stuck in a state of dimensional flux, existential flux, and insanity. They flit in and out of existence. They ignore matter and Space Pirate shields. They cannot ignore Samus' shields.
5. Ing attack. The Ing are prone to using "transdimensional energy" to attack, meaning they attack between dimensions. They often open portals and tear holes in the fabric of space to attack. Some of them (Hunter Ing) are able to attack from another dimension altogether. Ing are also capable of spiritual possession, which is like demonic possession but worse. Samus' shield blocks all of this, Space Pirate shields do not.
6. Life Energy shield. Any way you look at it, Samus does not have a normal shield. Add to this that she fairly often often absorbs the life energy of creatures in order to recover shield energy. She can also recover missile energy this way. After Metroid Fusion, she can absorb energy directly from X-Parasites without use of her suit.
This good enough to protect her from the Lich King?
