10 Comic Book Characters That Broke Wolverine

10. Professor X

When Professor Charles Xavier asked Wolverine to join the X-Men, many readers assumed it was the first time the pair met.

But it wasn’t. Years ago, Wolverine was brainwashed to kill Xavier. As he got close, the professor wiped the brainwashed section of Wolverine’s mind. Instead of sending him away, Xavier implanted the idea in Wolverine’s mind that would eventually make him join the X-Men.

When Wolverine learned this, he was astonished that his mentor would manipulate him like that. Sadly, this wasn't the only time he saw a darker side of Xavier. During the 1990s, Logan learned that Xavier had a protocol to kill the X-Men if they turned evil. According to the protocol, Wolverine should be killed with a “long range attack, sever the head, and place the head and body apart.”

But it doesn't stop there. When Xavier upgraded the Danger Room's AI, the technology became self-aware. Although the AI felt like a prisoner inside the room, Xavier refused to deactivate it, believing he needed it to train the X-Men "whatever the cost". Wolverine was disgusted when Xavier said this and compared him to Magneto. After being let down by Xavier time and time again, Wolverine stopped trusting his tutor.
