Treasure Trove.

When the advantage of speed from speed force is combined with the ability to revert to his previous position and his perception of danger, it is nearly impossible to injure him.

So he was ready for battle. However, his enemy was not.

He flashed around the puppet, attacking it, but no matter what he did, the puppet didn't retaliate. It didn't even move. It just stood there and continued to look ahead without blinking.

It also began to fall to the edge of the world. But it didn't react to that.
