Wait wait wait.
Great cataclysm is right in the middle of happening, as in movie 2. Makuta's laughing, fighting Vakama as usual. Suddenly, a yellow Toa appears. He's wearing a plain, completely round mask with no features whatsoever.
"Who are you, daring to challenge me in such a flippant manner?" asks Teridax.
"Just a guy who's a Toa for fun" replies the stranger.
He then punches the Makuta, who immediately disintegrates completely.
ONE PUNCH TOA.
