Mine just came in the post. I added Predacon symbols to mine and included some colour-coordinated minions for company.
Combining this was an absolute pain. The two 5mm port system feels both loose and too tight at different times. Attaching the knees to the smaller dragons needed force, which then caused the other connections to pop-out. It feels like it's going to pop apart at the slightest bit of regular play, IMO.
As a display piece, it's ok and probably worth the ¥8,000-ish I paid for it. It will look good next to TM2 Megatron, Gigatron and the other dragon bots.
In other news, this chap, coincidentally, was released in Japan at the same time. Even though there's meant to be a molded Predacon symbol inside his (once disassembled) opaque spark crystal, I popped a sticker on .
Also, a Japanese review of "World Dragonus" is out (with English subtitles).
