Minecraft Story Mode:Prismarine Soldier

Prismarine Foes are a group of prismarine statues who help Romeo protect the Sea Temple by killing intruders. They first appear in "Hero in Residence". Several Prismarine Foes are frozen in the room across from the treasure room where the Structure Blocks are shown. After Jesse chooses a Structure Block, the Prismarine Foes break into the room and attack Jesse's Gang.

Appearance and Variants
There are two main types of Prismarine Foes:
 * Prismarine Soldiers are small Prismarine Foes, standing at around 3 blocks tall. They appear to have a beard and have glowing, green eyes. Most wield prismarine axes, though some have prismarine bows that fire prismarine arrows and the rest wield prismarine swords.
 * Prismarine Colossi are giant Prismarine Foes that are 20 blocks tall. They also have glowing, green eyes, but with shorter beards. Romeo used one as a secondary body.

Trivia

 * Their name, "Prismarine Foes," was confirmed in the choice statistics of "Hero in Residence".
 * They have a glowing symbol on the back of their heads that acts as a weak point. When stabbed there, the glow in their eyes will fade out and they will die.
 * The design took inspiration from Cthulhu.
