Kotobukiya's "Highend Master Model" (officially abbreviated as HMM) series was a model line consisted of Zoids and Customize Part kits. It was a joint effort between Kotobukiya and Takara-Tomy. It features highly detailed, pose-able injection-model kits. There was no unique backstory for the line; information recycled from previous medias about the series' Zoids were included in the instruction manuals. Kotobukiya officially announced the end of Chapter One of the HMM line on December 14, 2013. The final Zoid was the Gojulas, sold in December of 2013. See HMM Chapter Two for later releases.
