To answer your questions in advance: The software used is Flash and After Effects. That's why you might spot some quality loss (due to the Codec). You may view this on Youtube (search Crocodile Aniforce) in 1080 or 720 resolution without that quality loss!
The voice-over of Crocodile is Alison Stark. You might have heard her voice before in the animations of Newgrounder: Eddache (and I advice you to watch his animations!)
