How about,

Nickelae's pride as a fighter often leads him to deny any sort of fear he may feel towards his enemies, even though some grimms like Nevermores frighten him. When faced with one, he may put on a brave face and force himself to fight but inside he'd be terrified. This often leads to him unconsciously using more dust in his attacks to make them stronger.

He is also sometimes easily controlled through his anger. This sometimes leads him to take unnecessary risks.

How's this? :D
