Sheero, Veteran Toa of Ice (Slide 6): Sheero has been a Toa longer than most and acts as the mentor of the Toa Arga. The death of his previous team mate and best friend still haunts him. As such he tends to be quite harsh.

Krana Sentry (Slide 3): In the new found settlement of Atero Nui on Spherus Magna, a Po-Matoran named Velika has discovered the ability to "awaken" the Krana housed in all the Bohrok now scattered from the reformation. These Krana are used to power and control all sorts of machinery ranging from vehicles, to construction bots, and in this instance, combat sentries. They are quite useful to have around!
This was inspired by the Vercadian Protector Droids from the Star Struck Comics. (Any other D20 fans here?). As well as the Protectrons from Fallout.

Unamed Fire Toa (Slide 2): Wanted to try out using Ackar's shin pads as shoulder armor, but I think it worked better on the krana sentry. Not sure if I'll keep him as a member of the toa team.

(Edit: Sorry, not sure what happened to the picture order)
