I hope you will appreciate these models. Every constructive suggestions to enhance the models are welcome.


Your Tren Krom moc is legendary.


The Karzahni and Ahkmou are alright, but that Tren Krom is wild. First actually scary one I’ve seen in a long while. Too bad it’s almost entirely clipping.


That Tren Krom looks amazing, but I think better renders would help to really appreciate the build. Just for curiosity, does it have a third eye?

I really like Karzahni, he looks like something that could have been realse as a set (with exception of the mask)

As for Ahkmou, kinda hard to tell that is him. Maybe change the red for brown or tan.


I’ll correct the file.
Thank you for your feedback


these all look fantastic!
tho karzahni’s thighs could be a little beefier


Thank you.
I wanted to keep the model close to the original artwork, which has frail tighs.


Ah very nice spooky mocs! Karzahni is pretty good and Tren Krom is outright terrifying. Ahkmou is neat as well, awesome job.


The original model did’nt have one (I forgot to add it), but I corrected that by modyfying it a bit. His third eye is on the top of his head

“It was at this moment Carapar knew…
He messed up !”

Concerning Ahkmou, in second thought, yes, you are right. If we refer as the Kardatoran, Ahkmou should have kept his brown color after transforming. I originally wanted to make a Makuta color scheme. Here it is:

I’ll update everything as soon as possible. Thank you for your feedback


Very nice. I like the black brown combo


Galva’s Great Rau works surprisingly well on Toa Ahkmou - I didn’t expect the mask to look that menacing.

Awesome Tren Krom model - it’s nice to see someone actually try and build him.

Also, is that a Great Being in the fight for the mask of creation picture? Will you showcase them too?


Thank you.
Yes, it is a great being.
I’m still working on some of them, but sooner or later, a topic will be dedicated to them.
Stay tuned.


Very nice design. It literally brings him from the artwork and into reality. But i always think of the shoulder pads in the bionicle guide are closer to Ehlek heads because of how spiky those heads are.

But why exactly is Karzahni black/gold when he is fighting for the mask of creation ?


The choice of the piece for these shoulder armor was always complicated. No official piece actually fit completely the role, and even accurate custom parts are rare. I’ll try to see how it would look with ehlek’s head.

Concerning his color, apparently, in Dark Destiny, his armor was black and gold when he encounterd Jaller and co, but changed after.

(No, it’s not a lack of communication between each team at lego)


Still he’s just very odd in gold and black.
If he had a version before the dark/blue green…i would have imagined him as the rust color from LDD designer program.

As for Tren Krom it’s really good.
