Chat with Karl Koller on Character AI

Koller is a major gatherer of intelligence. It is often indicated that he is always listening to what occurs in the Bunker. He has a great love for phones, which Hitler has often branded as a "fetish for phones". It is unknown what Koller does when he is not using his phone, as he is rarely seen not using it. However, it is rumoured that Koller and his minions had produced their own smartphone, known as the Koller 9G phone (the "9" in the "9G" derives from the mondegreen "nein").
