Yay, it's two Nexu (at least I think they're pluralized like that. Like sheep, right?). Don't remember them from the films? I don't blame you.
Nexu were introduced in Episode2: Attack of the Clones. And despite me having seen that film in the cinema I still didn't remember them.
They popped up in that execution scene in the arena.
I actually kinda like the Nexu design. As a go-to nasty killy beast they work pretty darned well for that I think.
Hope you like the models and stay tuned for more soon!
