LN9 - 7 - Mask of Speed

Lewa yanked on the chains. They were made of protosteel, one of the hardest substances in the universe, and so thick even Pohatu would have a hard time breaking free by sheer strength alone. Of course, a quick use of their elemental powers could get them loose, and the Makuta had to know that.

Pohatu Nuva gave a mental yank on the section of stone he had weakened. The floor beneath Antroz’s and Mutran’s feet gave way, throwing them off balance for one crucial instant.

As soon as he saw them start to fall, Pohatu triggered his Kanohi Mask of Speed. By vibrating his body’s molecules at high speed, he was able to pass his wrists through the chains and free himself.

Increasing his vibration, he rocketed forward, using his hand to slice through the chains that bound the other three Toa. Then he was gone, headed for the chamber where the Matoran were being held.

By now, Mutran and Antroz had regained their footing. Lewa and Kopaka had retrieved their weapons and, along with a newly revived Toa Ignika, were ready for them.
