Mr. Game and Watch is Kelly's best main. She used him for previous competitions and is known across the whole team for having the best luck with Mr. Game and Watch. Mr. Game and Watch is also Kelly's longest used main, with 3 years of playtime. A move exclusive to Mr. Game and Watch that makes him a character to be cautious around is his Side Special move, Judge. When used, the game pulls a random number from 1-9 and the number Mr. Game and Watch lands can never be the same back to back. The number ranges in damage to where 1 does damage to yourself and 9 is so strong it is almsot always an instant K.O.
Mario is Kelly's newest main with only 5 months of playtime. Mario is best known for his strong aerials and combos that are annoying to deal with and pull off to those experienced. Mario's ladder combo makes it so he can take opponents to the top of the map using just Up Air, and when high enough, Mario's Up Special takes out the opponent and not himself.
Banjo and Kazooie is Kelly's secondary character, she'll pick Mr. Game and Watch and Mario before Banjo and Kazooie, but has enough experience to run him through competitions. Banjo and Kazooie are Kelly's second most played character with 8 months of playtime. Unlike other DLC characters, Banjo and Kazooie have only one thing that gives them what is known as DLC Privilege, which is his Side Special, Wonder Wing. Using this move grants Banjo and Kazooie temporary invincibility while using it, but due to limited stock and some moves being able to disrupt the execution is why Banjo and Kazooie aren't used as much as other DLC characters.
