These pixel papercrafts are 2D Varia Suit and Power Suit Samus Aran, based on the action-adventure video game Super Metroid, the paper toys are created by Oakusan Crafts. There is also a Samus Aran's Phazon Enhancement Device (PED) Papercraft available.
The Varia Suit (referred to simply as Varia in Metroid and Metroid II: Return of Samus and Varia Feature in Metroid: Other M) is a Power Suit upgrade. The name is a mistranslation of the word "barrier" (interestingly, the Metroid II manual uses Barrier Suit anyway), pertaining to its usefulness; the Varia Suit reduces damage taken, nullifies damage from Acid, slightly increases speed, and protects Samus Aran from extreme heat and sub-zero temperatures.
Samus is most commonly depicted wearing this suit, but like many of her other upgrades, it is lost at or prior to the beginning of most games, requiring her to track the upgrade down at a later point in time. The maximum temperature that the Varia Suit can protect against is unknown, but the Gravity Suit is generally required for some of the higher temperature liquids.
A Power Suit is a suit of powered armor designed by the Chozo. This term applies to both Samus Aran's Chozo Battle Suit Ver SA1-4468-VM6-P in its basic form without any upgrades, and her suit as a whole regardless of its current upgrade level. The word "Power Suit" is short for powered armorsuit. A Chozo known as Dryn was apparently instrumental in the development of the technology, and Mother Brain claims to be the creator of Samus' original Power Suit.
Two specific models are well-known: the first is a suit given to Samus in her teenage years by the Chozo who raised her. After being attacked by Space Pirates and left stranded, Samus lost her spirits and was unable to summon the suit. After completing the Ruins Test, her fighting spirit is restored and her Power Suit is upgraded. Presumably, this second Power Suit is an ancient model, given its depiction in Chozo prophetic murals and its compatibility with some of the oldest Chozo-produced upgrades such as the Space Jump, Plasma Beam and Gravity Suit.
