First, i'm really don't know why it call as "kai" but i just realize "kai" is something means upgrade but whatever is it, it doesn't have the flightpack, normal Gat-x series shield and the Astray Beam rifle. If anyone of you think that the articulation will definitely better since the NG 1/100 version already have great articulation, there is a price to pay for that. Alright, should start it with some introduction instead of complain.
The origin of this MS was from Orb, one of the five prototype unit. Pilot by the Lowe Guele, appear in the side story of Seed. I actually read some information from MAHQ and i just learn that Astray doesn't have phase shift technology? and as a highly develop country, it need to copy the technology from the alliance for the beam rifle and beam saber? Alright, this sound quite ridiculous but it might be true. The original weapon for it was a one beam rifle, 2 x beam saber, Gatx shield and vulcans but due energy limitation, this unit also equip with "katana" which called as Gerbera Straight. I don't have much information about this MS as i didn't follow its manga story and only few short clip anime showing this unit. I do saw some of it manga story appear in the Dengeki hobby magazines but its seems the story is quite boring (no big scale battle and lots of talking).
As for the kit, I'm really don't understand why Bandai slot in the tactical arms which can transform into a "bow" while there are many other better options such as only offer the MG kit with its basic weapon, then the MG flightpack version comes later. Similar to the PG version that this MG version will get two gerbera straight Katana but no beam rifle, beam saber and shield. There are lot of spare parts which come from the MG astray blue frame second L but those part are insufficient to transform it into second L and a lot of spare part left after the completion. So, lets check the box art and the runners.
