Bamster

The Bamster (バムスター), also known as the "Colossal Neighbor," is a Trion Soldier made for capturing. They are specifically created for Trion gland extraction. This is the Trion Soldier that comes into the civilians of Mikado City's minds when they hear the word "Neighbor." They are the size of a multiple-story building, and have tough skin, but are not very strong overall.
