Tetsuo would find Azula very intimidating, after all she's pretty and really smart and super classy! The violence, though, ehh, lots of people are violent, that's kinda whatever.

1) Not intimidated in the least, because that is a child who needs help, even if she is a human flamethrower/Tesla coil
2) Very intimidated
