As Mata-Nui won the fight against the leader of the Skrall, Tuma, he was walking outside the Arena Magna. Everything was peaceful, until three Skrall and Atakus attacked him. They wanted to kill him, they were afraid that Mata-Nui might be interfering with the Skrall's plans. At first Mata-Nui tried to convinced them that he is not interfering with anything but when he heard one of the Skrall talking about conquering Bara Magna, he became concerned for the people on this planet. And so, the brave and noble Mata-Nui delays the search for his home and decided to help these good people. But with that decision, the skrall attacked. But before they got the chance to attack, two flame swords, one small and one bigger smashed the Skrall to the ground.
"Who are you?'' Mata-Nui asked.
''I am Raanu, master of combat and leader of Vulcanus.'' Raanu replied.
'''My name is Ackar, I decided that I will fight for Vulcanus since the exile of the great Malum.'' Ackar replied.
''We will help you, for now..........."
