At first, Gus was a timid and shy young boy, who had a tendency to be defensive and secretive due to self-consciousness about his own Semblance and its negative effects. He is a convincing liar who uses his Semblance's effects to indirectly try to do good, as he does not like fighting.
August has strong adversities to be a Huntsman, but by the end of the novel, is somewhat more confident and less against the aforementioned field of work.
Powers and Abilities
Gus' Semblance allows him to amplify the emotions of those around him, whether positive or negative. However, he can only amplify emotions that the target is currently feeling, such as Bertilak Celadon's anger against Team CFVY.
Additionally, Gus is scared to use his Semblance, as he has not mastered control over it and he fears the amplified emotions would attract the Creatures of Grimm. His Semblance is considered to be very powerful if it were mastered.
Edward hired Carmine Esclados and Bertilak to safely transport them to the settlement of Gossan, in Vacuo. The group eventually reached Gossan, but then moved to Feldspar as the original settlement was destroyed by Grimm, where they met Team CFVY.
During their travels, Gus' Semblance would have to consistently be blocked by his grandfather.
The Huntsmen-in-training lead the nomadic tribes to the settlement of Coquina, but when a sandstorm blew over, Carmine and Bertilak revealed their scheme to kidnap and traffic the Caspians to an unknown employer for their Semblances. Carmine kidnapped Gus but was prevented from completing her objective and arrested by Team CFVY. Edward and August arrived in the settlement of Coquina safely, along with the other travelers.
