Metroid Render
This is a Metroid, the creature the Metroid game series is named after. While this is not really a render but a fan art of the Metroid with a transparent background, we call it a render since that is such a common name today for art like that.
This Metroid was drawn by Green-Mamba from the USA who created this as a part of his own tribute to the Metroid series. If you like this, check out his other works here on Game Art HQ as well, also visit his gallery on deviantART where this guy shares a ton more really cool art!
