Isaac isn’t fully developed yet, but he’s one of the main companions so I tend to treat him with care. He serves as the team’s information broker and despite not being the smartest of the group he has the most street-savvy and tends to know what makes people talk. He’s charismatic and knows how to persuade almost any creature. He cheats death a lot and walks away unscathed most of the time. Not due to any strength but he’s just an all-around lucky guy, lucky to be alive with nothing but reading situations. He gets on Shadow Spade’s nerves but she respects him for his information gathering skills and secretly envies his communication skills.
 
He’s one of the few male companions Shadow Spade encounters (since I generally prefer mares)
 
Him being a bicorn is a radiation mutation, he’s actually just a Unicorn that got a bit of Rad sickness at one point of his life.
