Here are some bionicle mocs that I made, first the mahri mods.

I thought I would use the mantax skull as an air tank.

I will post the other mods soon. Tell me what you think! Click here you more pictures.

These seem good, I'm going to look at them individually though.

Hewkii: Wow. I think this looks a little better than the actual set (I'm still not a fan of the mask). Looks good, but the attached chains could be detached, and the Mantax head looks a little awkward (plus, add some thigh armor). It's seriously really good though.

Jaller: This one, I'm not a big fan of. the black offsets the set. I think the Dark Red/Black color scheme works well, but the orange is like whoa. I like the torso and the sword however.

Very nice, I especially like the idea with that air tank, pretty cool!
