Jason returned and give his testimony on what happened with the mutant beast. According to him, he and Alex fought an injured mutant beast on the verge of evolving to the tiger threat level and although that sounds lame, everyone knew the strength gap between a wolf treat level beast and a tiger threat level beast is as far as the earth and the heavens.
According to him, Alex utilized the matter absorption ability to absorb the properties of his beast gear which enabled him to fight the beast head-on. After investigation, it was confirmed that the black spear was a weapon that surpassed the wolf level but was not up to the tiger level.
How he got it was another question but that had nothing to do with Alex.
