Chainsaw banki was pretty damn scary, but then again, I have a phobia of chainsaws and other power tools that involve cutting.
I wonder how they will handle the StrawBanki episode, because that was a clear "Don't do drugs, they make you do bad things" episode, with Renn and Sousuke being exposed to the StrawBanki's power up formula, and going bad.
HammerBanki was fairly violent.
