Professor Red was never really someone you could relay on for being able to fight in a War, he wasn't good at it. At least, that's what everyone said, what everyone thought was true. Well Maybe he did know how to fight, But they would only Learn when something that no one wanted to fight came to try and destroy them...
The Professor May be Insane, He may be Crazy and Cheerful, he may experiment on things he shouldn't but he isn't a Coward. He will Protect the people he cares about, even if it results in him having to let everyone know that he can fight, and that he remembers more then people think.
