Pollux is initially prideful and cocky. However, he is seen, more often than not, to have a soft and childish side. He deeply cares for all the members of the guide committee and, alongside Arcturus, are at the emotional core of the friend group. He always aims for everyone to have fun and enjoy themselves, even if his plans don't always go well. He also has a very insecure side to him, given the side effects of his constellation choice. Pollux is mute. Pollux is tsundere.
