Nah. It was Ridley. I think he actually ate them, because in the comics or books, he makes a comment about how her mom tasted. I know he doesn't talk in the game, but he talks in the comics and books.

Samus was born on the mining colony K-2L, mining a valuable mineral called afloraltite that was used to power **** . Very valuable. Space Pirates raided the colony. Her dad was killed while blowing up the Pirate raiding vessel (sacrificing his life), and her mom took a deathblow that was meant for her.

meant for Samus*. So yeah, Ridley technically only killed her mom, but is largely responsible for the destruction of the colony and the deaths of everyone else that he did kill and that his forces killed.

The Space Pirates attacked Zebes where both Mother Brain and Samus's family were stationed. Mother Brain turned on the Galactic Federation during the assault.
Ridley and Kraig however were the ones originally leading the attack with Ridley himself striking Samus's parents dead.

>Kraig
Casual not really, it's an obvious typo

wtf you mean, everyone knows craig was the hardest zelda boss
