After seeing so many ways that it can be done, now it's time to ask the question of How Do We Do It?
For this look, we're taking a peek at Codename: Kids Next Door, and for this one we have a special guest commentator! My boss, Leonardo McDowell aka Darkton has been writing fanfics for the show for years, to the point where he made a dedicated timeline for the show. If anyone knows KND, it's him. Here's what he said:
"First of all, you're crazy, Arc, for getting me to do this. And not just do this, but do it TWICE! Why didn't you keep a log of what I said before? Ah, still, I'll see what I can do to remind you, because I'm such a nice guy.
Kids Next Door is a series that takes typical childhood concepts and dials them up to eleven to turn them into epic adventures. Eating a Brussels sprout POISONS OUR HERO!! Brushing your teeth IS MUTILATING YOUR MOUTH!! Stuff like that. The two big examples of nudity, BUTT and DUCKY, involved these concepts. He lost his swimsuit at the beach, NOW THE ENEMY HAS BLACKMAIL TO GET HIM TO STOP FIGHTING!! He doesn't want to take a bath AND GETS SUCKED ONTO A SHIP OF LOST SOULS!! Any new story should play off those elements. I bet you could write a rockin' fic about a horrific game of Doctor WHERE THE DOCTOR IS A MAD SCIENTIST!! Still wonder if that'd be better from a girl to a boy, though; Doctor is all based around the differences between the two, and I don't think you'd want it to look like sexual assault (I don't).
There's also those brief, quick gags that cartoons love to use. For example, the Nude Torpedo in ARCTIC that you seem to like (a lot) or Tommy mistaking what a Birthday Suit means to the KND. Stuff like that really needs no explanation, just use it wisely.
One more thing; KND is a show based around the idea of a central continuity, with consequences from one episode taking place in another. This was introduced when the age-changing cigar was brought back for the Season 1 finale, and it's been used all over the place, like with the Boyfriend Helmet from Season 1 being used back in Season 4, or Tommy putting Father's DNA into the Code Module in Season 3 coming back to haunt him in Season 5. Perhaps you could find a practical use for the Nude Torpedo, like destroying a kind of armor of some kind, like an enemy's strong one, or a cursed one hurting a friend.
Anyway, I'll leave you back to whatever you're doing. And lay off the nanos, they ate buildings and objects more than clothes (never)."
That's all he wrote! If you're looking for advice, feel free to ask him for more. His name's Darkton93 on DeviantArt, where he spends most of his time. Tell him Arc sent you!
