Guardian Ghidorah

Guardian Ghidorah (ガーディアンギドラ Gādian Gidora), also known as Zmey Gorynych, is a Three-Headed Titan that appeared in Godzilla: Lord of the Galaxy.

Name
Zmey Gorynych or Zmei Gorynich is a type of giant, often multi-headed Slavic dragons. This name was given for this Titan by humans. The Shobijin fairies call this Titan as "Guardian Ghidorah" due to his nature being different than King Ghidorah's, being a protector of Earth rather than a destroyer.

Design
Guardian Ghidorah has three heads, like every other Ghidorah. His genereal body shape is thinner than King Ghidorah's, and his wings are smaller. His heads resemble the GMK Ghidorah's heads, each one having golden "crowns" and the middle one having the biggest crown. Ghidorah's tails end up in an arrow-shaped tips.

Origins
Guardian Ghidorah is a relative of King Ghidorah, however he's much smaller.

Gravity Beams
Just like King Ghidorah, Guardian Ghidorah can fire golden Gravity Beams from his mouths, however they're not as powerful.

Flight
Guardian Ghidorah uses its wings for flight.

Durability
Guardian Ghidorah is immune to any man-made weapon, including Oxygen Destroyer.

Regeneration
Just like King Ghidorah, Guardian Ghidorah is capable of regeneration.
