La troisième épreuve

What was once a peaceful seaside village becomes a battleground as Goku and Pan square off against Oceanus Shenron, the 6-star dragon. Goku is soon caught in the fury of the dragon's assault and unable to break through Oceanus Shenron's powerful defense. The situation becomes more dire with every passing moment until Pan is forced to take action!
