If you were expecting a transformer or robotech where maybe one or two peices were needed for the flight mode you might want to keep looking. You literally have to take it apart to change it and i know its from japan, but the all japanese instructions barely help (but did we really buy it for the flight mode anyway?).as for accesories you have extra hands (of course), some alternate armor peices, the clear ange pilot (now i see why they didnt give any details. Still wish it was at least solid though), panels for the wings in flight or destroyer mode, and the flight mode cockpit with gun (gun is removable.) pretty reasonable id say. It does have a built in port though so it'll work with a gundam base figure Stand.all in all i dont regret buying it at all and just for the look its worth it (considering a deluxe transformer would probably be the same price if they had all the painted details and molding this has). My only real complaint is that it doesnt include a stand unlike some other display figures. Unfortunately this is one of the figures i wish they removed the transformation for stc cannon peices. Hopefully they'll do that with embryos hysterica since unlike the rest I don't remember it ever transforming into flight or really anything else.One problem though; one of the wing peices for destroyer (the spread fins) will not stay in at all. I've used a tool to just hold it for a minute and the peice just flew off. I got it to stay once and currently it's being held in by silly putty. And it's just a wing; the other works perfect. My only other problem is that there's so many peices it's definitely a "one pose and done" figure.Also this is my first tamashii nations figure but I got a fluorescent pen. Maybe someone could explain that as the instructions and figure feature no mention of it.
