Classification: The Red Giant Pokémon
Description: This is the form taken when the Pokémon has burned out most of its internal fuel. It may be nearing the end of its life, but it’s larger and more powerful than ever.
Evolves from Astar with use of a Sun Stone
Trivia: The sheer size of Gigastar makes it more bright than Astar, but despite this, its actual surface temperature is cooler. At this stage in life, it will only continue to cool as it grows older.
