Viu E. Blaze/Personality and Relationships

Personality
He doesn't seem to show much interest in things or be suprised by them, this is shown by how he reacted to the volcano erupting on Raven's Point. It should be noted that before Raven's Point, his personality was much different. Having a rather nice, laid back mood as apposed to the one he sports now. Whether this was a facade or something more has yet to be seen.

Nitro V. Kaian/All of the ThunderScars
During Viu's time with the Thunder Scars, Viu's personality was completely different. Being a rather laid-back, fun loving kinda guy. It's unknown if this was simply a ruse, or if he prefered their company over his current company.

Ryder Nakamura
The first person that Viu convinced to join his crew, and apparently his First Mate as well. Even though they're supposed to be close and trusting of one another, Viu seems to still treat him like a pawn, controlling his mind when he refused to make him lunch.
