of Hamegg. Skunk, meanwhile, brings Atlas with him for his next plot, which is to cause icebergs to sink a ship and have Atlas recover the gold transported by the ship. Tobio foils the plan by attacking the icebergs. He meets Atlas and they both realize that they feel they already met each other in the past without knowing how, then fight. Astro is drained out of energy and falls unconscious at Atlas’ feet. About to destroy him, Atlas forgives him remembering of Livian's words who told him to not take advantage of weak people.
