How do I remove a certain player from a table?

So I made a monster that spawns and the monster will not count as a player, otherwise the game will never end. But I cannot figure out how to do it. Can someone help? Here's my error: 20:14:09.658 - ServerScriptService.Script:61: bad argument #1 to 'remove' (table expected, got Object)

And here's the script where the error came from.

 local status = game.ReplicatedStorage.status
local timer = game.ReplicatedStorage.timer
local plrsLeft = game.ReplicatedStorage.plrs
local gameTime = 70
local intermission = 20

local id = game.ReplicatedStorage.ImageId

	status.Value = "Waiting for more players."
	plrsLeft.Value = "0/".. game.Players.NumPlayers
	repeat wait(1) until game.Players.NumPlayers >= 1
	for i =  intermission,0,-1 do

	    local seconds = math.floor(i%60)
