Technology & Combat Characteristics
A variant of the Beginning Gundam, Takeru built it based on a design plan he found in his grandfather's home. The "J" in its name stands for "Japan", and is given by Figlia Contini who mistakes Takeru as the builder representing Japan. The 'circle of sun' in the Japanese flag serves as the motif for the Gunpla's red color scheme.
The Beginning J Gundam maintains the high basic performance of the original Beginning Gundam, but has enhanced close combat capabilities to match Takeru's battle style. Its main weapon is the pair of "Burning J Swords" stored on its back. Like the round units mounted all over the Gunpla's body, the swords are equipped with the 'IFS' units (I-Field control System unit) first featured on the GPB-X80-30F Beginning 30 Gundam.
History
The blueprints of the Beginning J Gundam that Takeru found in his grandfather's house was actually created by Bandai Hobby Division to evaluate whether the Gunpla should be commercialized. The Gunpla was later released as an actual HG model kit and known as "late type" to differentiate it from Takeru's own scratch-built unit, which was called the "early type".
