I say Zelda. I've only known one person to main Zelda... Two others who even use/like her.
No, I main her, and I know many others that do too. She stays.
You Should Get rid Of DK Nobody uses him and he doesnt even have a decent PSA. Or Peach Can Go.
No. Same reasons for Zelda, and hell no to DK. I started maining him, hell, he's even been in 64.
Diddy can go, everyone else is either most likely staying, or has already been replaced by a completely different character.
