Come To An End
You see a tsunami that's simultaneous (with another tsunami, I assume) and you know the world is about to come to an end.
Imagine a tsunami simultaneously happening as the world comes to an end. Oh no, isn't there any way to stop this!?

None
Just as the world is about to come to an end, your cyborg (さい) appears and blocks it with its cyborg body!
So the world won't come to an end this one time, thanks to the cyborg you made. Though it doesn't look very good. The cyborg is beaten up and full of water. This might be the end for it...
