Holographic rainbow Titan Dragon

Seen here depicting a holographic rainbow titan dragon a celestial being that can grow bigger than gas giants or even stars.

They sleep on planets usually feeding on the habitat. Until they're big enough to dig into the landscape usually feeding on minerals underground livestock and sometimes even the core of the planet themselves depending on what they're made of.

After the feast the dragon carries on towards another planet to repeat the same process.

Despite being both mystical and beautiful this deadly hostile creature means certain doom for whatever planet it lands on as it's extremely territorial and if threatened unleashes energy from several portions of its body that tears through any known material.
