Root Changing the powered off charging screen?

I don't like how the Motion doesn't show the numerical % of charge when charging (power off).
Is there any way to change that screen?

I think there is. But I wouldn't know how.

I was porting a few roms for testing and like I made a mistake on one and I got the morning call error but instead it said "morning call empty". I powered off and plugged the charger in but instead of showing the default battery charging animation I got a black screen with green text showing the percent and stuff.

It was basically showing me the stuff that's going on behind the animation.
