From what has been seen so far,it's clear this show is still in production,but anyway,I thought I would give my thoughts on it. Codename: Kids Next Door,KND for short,was one of my favorite cartoons of the past few years,and I was very sad when it ended. It was a great show with an awesome premise,a very good art style,and memorable characters. Fast forward to now,it's fanbase is still big,and it remains one of the great cartoons of the 2000's. Many fans of the show were surprised when a teaser for a potential continuation of the series showed up on YouTube,including me. Though some people are convinced that it's an April Fools Joke due to a countdown set to end on March 31st,11:59 PM. Anyway,onto my thoughts. It shows great promise,setting up a dark premise and setting up what could be an interesting story. Numbuh 1's new design and attitude clearly shows that he has grown,although it also shows that something has happened to him in the years since his departure from Earth,showing a hatred for all adults,both good and bad. Guess he must've ate some War Doctor peanuts. Numbuh 1's voice actor,Ben Diskin,who fans of Kingdom Hearts know as the voice of Young Xehanort,sounds almost exactly the same as when he started voicing Numbuh 1,and that is a pretty great thing too,since it shows that even though he has grown,he can still pull off the voice of a British dude with sunglasses. I honestly can't wait to see this when it's complete. KND has been a big part of my childhood,and seeing the potential of its return makes me very excited. Sorry if this doesn't make much sense!
