I declare a challange. Build the OoMN members who aren't sets. This includes Mutant Brutaka. Here's a list and suggestions:

Jerbraz, pre invisibility.

Roughly 8.5 feet (2.55 meters) in height, Jerbraz is completely invisible as a result of a failed experiment. He thinks very highly of himself, and once described himself as being considerably handsome prior to turning invisible. As with all Order of Mata Nui members, Jerbraz has his mind shielded against telepathy.

Ok, I've done my MOC of him, and based on the bolded section, I'd assume, make him look good. White is probably the best color (and that's what I made mine) to fit that personality, just putting that out.

Helryx

Don't worry about making her frail, scarred, pitted, etc. Just build her. I didn't do anything like that.

Johmak

I have no ideas...

Tobduk

I personally think of him as orange and beastish, but that's me...

An unnamed giant member with four arms and horns. He carries a multibladed axe.

Greg thinks of his colors as dark red and purple, if you don't have purple, like me, black looks good. Don't ask about the axe, I have no idea other than what I did on mine which was very hard to pull off...

A member who met a dying Tahtorak who revealed that the Tahtorak on Zakaz plan to wipe out the Skakdi.

I personally made this one sort of beastish and feral, if he/she was on Zakaz with the Skakdi, you'd think the being would have to be powerful or feral or something to get in and out easily.

An unnamed spy on Destral.

Don't worry about this one. I'm not doing this one since we have so little to go on. I'd assume one of the Barraki's species however, but don't build this one, or Botar's replacement.

Brutaka.

he now has spikes jutting from his armor and what looks like a dorsal fin on his back.

Don't worry about the helmet, add gills, the fin and spikes and you're fine.

I will post mine when the contest comes to a close. I also will pose them with Maxilos, Hydraxon, Axonn, Spinax, Trinuma, Mazeka, and every other Order related being I make or have (including making a likely horrible looking Kratana).

Have fun.
