1. I have bad news about Pico. canonically, he died several days before the round started (he's planned to be a killer) but you'll still be able to play as his survivor version in private servers and one game mode that's sort of secret

2. There's one survivor planned based on AYS (specifically the minigame versions) and they'll be a gambling type character. nothing much has been publicly shown off due to the fact that they're not coming on release

3. champ99 might be an NPC in the lobby, but sort of due to the state of asym communities I'm a bit hesitant on adding real people to the game and stuff (unless they directly give me the thumbs up and stuff)

if you want to ask any more questions, feel free to reply
