Deceptors

Information: 

Deceptors are giant cephalopod like beings that live only to destroy entire planets, some claim these beings to be completely evil, however the truth is much more complex, yes Deceptors do destroy planets, costumes their core and live within them in a similar manner to cocoons, however many scientific studies have shown that Deceptors suffer a strong and intense pain when they fail to consume a planet's core, while not an excuse by any means, it is at least a factor which makes people think before they call Decpetors outright evil.

As mentioned before, when Decpetors consumes a planet’s core they will pull together the crust of the planet and live within it, from here Deceptors will continuously hibernate for fifty years, once the fifty years are up The Deceptor enters space again to seek out another core to consume.
