The Bamster (バムスター Bamusutā?), also known as the "Colossal Neighbor", is a Trion Warrior made for capturing. They are specifically created for Trion organ extraction. This is the Trion Warrior that comes into the civilians of Mikado City's minds when they hear the word "Neighbor". They are 2-3 stories tall, and have tough skin, but are not very strong overall.
