The basic minifigures are a tiny bit shorter and a lot wider than the average LEGO fig though. Their weapons and accessories are compatible, but interestingly their helmets aren’t. The Tenkai heads are much smaller, but still have a plug on top so they can still wear the LEGO helmets. Unfortunately the fat LEGO heads are just too big to pull off the Tenkai look.
Another big difference is that the Tenkai have a nice range of articulation. Their heads are on a swivel joint, and their shoulders, biceps, and hips are all ball joints. This puts them in a weird middle ground where they can move better than a LEGO figure, but without knees and elbows they still feel a bit lacking compared to what Mega Bloks or Minimates is doing.
The exception to this is Sho, who has a pretty strange design anyway. His neck and tail are double hinges, while his little legs/stands are single hinges. His arms (or wings?) are connected to the main body with ball joints.
Paint jobs on the figures are pretty basic. The body brick and elements are mostly molded the color they need to be. There are some minor paint apps on the heads, helmets, and chest plates though. One thing I really liked was the use of unique translucent colors for the accessories. Not only do you see normal colors like yellow and red, but there’s also a smoky black and a clear silverish color.
I’m always a fan of innovation in toys. It’s hard to compete with LEGO in their own sandbox. So creating a line of customizable minifigs that can combine with each other to create larger and better figures, vehicles, and accessories is pretty inventive. I do wish they had a bit more articulation, but that doesn’t mean these little Knights aren’t fun to play around with. I can definitely see this line becoming popular with kids.
