A limited subline titled Chi-Bi Senshi (a pun on the mainline's 'BB' and 'chibi', meaning small) consisted of thirteen kits based on Super G-ARMS, Knight Gundam, Gundlaner and Musha. The kits were smaller and less complex than full BB Senshi, built on a five-point skeleton block which allowed for parts swapping between the kits. This gimmick was also utilized with some of the Knight kits to allow them to combine with larger BB Senshi versions of the 'Kihei' mobile weapons they piloted. Additionally, nine of the Chi-Bi Senshi were released in three triple boxsets, depicting them in widely different transparent colours. The Comic World chapters included with these sets referred to these 'Crystal' versions as doppelgangers made from sentient alien crystals who had chosen to copy the real Gundams.
