The comics. I don't know which issue, but here is a quote from Wookieepedia:"Imagining them to be the Sand People who had kidnapped and tortured his mother, Anakin slaughtered them without pity. In the heat of his rage Anakin even tried to attack A'Sharad, but the elder Jedi defended himself, and managed to disarm the younger Jedi."
Anakin was a padawan at that time. His power dramatically increased since then.
I do agree that Krayt wins this though.
