Moveset concept for Carmen Sandiego. It's an amalgamation of every version of her.
Carmen Sandiego can steal items by simply walking pass other characters. Additionally, there's a 1/8 chance that she swipes items by hitting you. In fact, Carmen is such a good thief, she can even steal things like charged/stored projectiles (like Samus' charge shot, for example), buffs/status effects (Deep Breathing buffs, Monado arts, etc.), and take pocketed items away from Villager/Isabelle. Carmen can activate what she steals by pressing the neutral B button.
Down Special - The Babble On Ray (based off of the Babble on Machine from Word Detective). To teach players the importance of language, Carmen Sandiego steals their abilities to speak coherently by zapping them with her latest invention. It prevents characters from using any special moves for up to 15 seconds, or until they hit Carmen. Fortunately, Carmen likes a challenge, so the move can only be used up to 6 times per stock. Hopefully, keeping track of all of this will improve your math skills! Additionally, all sounds the opponent character makes while affected is distorted gibberish.
Side Special - Grappling hook. If tilted, Carmen drags opponents to her (Scorpion style). However, if the button is pressed like a Smash attack, after grappling the opponent, Carmen follows up with a kick attack to the face (they never protect the face). The smash version has a chance to steal whatever item the player is carrying once Carmen kicks them away. The grappling hook also doubles as a tether recovery.
Up Special - Paraglider. Press up B once to make Carmen dramatically leap in the air. Surprise! Press B again for Carmen to whip out her paraglider for a stylish escape like:
Final Smash - Where in Time/Where in the World?
The capture robot appears on screen, but Carmen dodges it and vanishes. Cue brief cinematic cutscene with an ACME detective acquiring clues/looking at a map of the world. End cutscene. Carmen returns and drops a random historical landmark (Pyramid/Statue of Liberty/Eiffel Tower/etc.) or even stage hazards from other levels that deals massive damage.

Taunt: She's gotta have the signature hat tilt:
Another taunt can involve looking directly at the screen (you) and saying, "Try to catch me, player."
Her tilt attacks can be hand-to-hand combat. Think parkour meets James Bond. She has a lot of fight scenes to work with, but the general idea is to make her overly evasive. I think her dodging a mouse cursor (like Duck Hunt dodges the zapper) for a couple of Smash attacks would be cool, too. She also has a boatload of vehicles, gadgets, and lackeys at her disposal, if they want to incorporate any of that.
