Kurenai has shown quick reaction speed, able to defend against Itachi's attack after just recently breaking out of her own reflected genjutsu.
In the anime, she can travel through surfaces and sense others through their chakra signature.
As a genin, she wore a similar outfit to the one she wears currently with the signature thorn pattern on it with a simple sash around her waist.
She also noted the stark contrast between the current Hinata, who refused to give up, and the former Hinata, who would give up easily.She asked Hiashi whether he was certain about his decision to have his daughter join the regular forces, he promptly dismissed her stating that the Hyūga clan had no place for the weak. She shows great concern towards her students and takes a vested interest in their growth, especially in regards to Hinata Hyūga due to knowing full well how Hinata was viewed by her father.When Hinata tried to offer Naruto some medicine after his fight with Kiba, Kurenai convinced Naruto Uzumaki to take it because she knew of her student's infatuation with him.When she learned of his death, she fell to her knees in tears and disbelief, and later laid flowers on his grave during his funeral.The truth of their relationship was made clear in Part II when Kurenai revealed that she is pregnant with Asuma's daughter, Mirai Sarutobi.
