When Jason was little, he wanted to sound as intimidating as he could for Robin, and so copied Batman’s behaviour and voice, and would also imitate Dick because he was the first Robin and just so cool Jason couldn’t help look upto him as the standard (still is to a certain extent for present day Jason though he’ll never admit it).

So today, Jason can not only perfectly embody their body language so much so that if you couldn’t see his face you would think it’s them, he can also uncannily mimic their voices.

He uses this to their utmost advantage and it results in chaos every time. Just image scenarios like you’re in Gotham trying to rob houses in peace at night, you hear “Well well well something darks happening.” and of course you’re fucked but it’s Nightwing so you’re not that fucked and when you look to the source of the sound you find yourself staring down the feared crime lord Red Hood aiming a bazooka at you.
