ビッグダイX上半身を形成する、中型爆撃機。Xボンバー可動機首部下面に格納されている。合体時は外見上明白な変形は行われない。左右スラスターには各一門、計二門のビーム砲を装備するほか、ビッグダイXの拳が隠されている。ほかに宇宙機雷等を装備している。
MainBody also known as Jumbody, is piloted by Barry Hercules. This unit forms Dai-X's chest and arms. MainBody doesn't come across as being the most nimble of the fighters, but its main weapon seems to be quite powerful and it's probably the most heavily armoured of the trio.
