Episode 11

Charles and Robo-Battler break into Heisenberg's Laboratory. With just the two of them alone, without anyone to hear what they're doing, and no reason to pull out and not go all the way... Charles is ready to ravage the place where Robo-Battler was born and make their greatest memory together yet... if such talk hadn't overheated him and alerted Heisenberg.

Using quick thinking, Charles stuns Heisenberg with a piece of metal and both escape barely with their lives. Heisenberg expects to see them again to take revenge, but remembers he hasn't paid his dues to the Shimano Family and quickly searches for the payment; but before he can find it, a bunch of Yakuza arrive, and before he can do anything, they administer the Shimano Family's ultimate punishment and blessing to him.

Kidnapped by the Shimano Family, what awaits him is unknown, but they'll probably make him disappear under his current identity...

After being beaten and shaved, something deeply changed in Heisenberg... he became retarded.
