I love this song, and I think that the first two verses are describing the comic book, TV and movie heroes that children emulate, but if you notice, the music changes for the third verse and becomes softer. I think this last verse refers to Jesus, for His hand is absolute, and He curses the thorn. I don't know what could be meant by he bite the fruit, though. He is the Last Adam, so his biting the fruit is not the same context.
