High Grade IRON-BLOODED ORPHANS (HGIBO) is a line of 1/144 scale Gunpla kits for the 2015 anime Mobile Suit Gundam IRON-BLOODED ORPHANS. It is split into two lines: the standard HG 1/144 model kits and High Grade IRON-BLOODED ARMS, which consists of accessories for the main line.
High Grade Iron-Blooded Orphans is the first High Grade 1/144 scale line to incorporate complete skeletal inner frames, which are usually seen only in the higher-end Real Grade, Master Grade, and Perfect Grade lines. The design of the Gunpla kits allows interchangeability of armor parts between different kits.
The Season 2 kits include Action Base extension adapters, and the box packaging and instruction manuals feature bilingual Japanese and English text.
