The last time a Dandadan character appeared in the manga - with date and chapter....
This work was done by me and is subject to becoming obsolete very soon, so I will bring updates much later. I hope it will be useful! By the way, I didn't forget Mai, it's just that there is no space, but her last appearance was in chapter 183 (11/24/10) and the undergrounds last appeared in chapter 50 (03/28/22) data taken from mangaplus where I recommend that you read the manga.
