Here is a solution using STUFF:

SQL

DECLARE @Heroes TABLE (
    [Heroes_ID] int,
    [Heroes_Name] NVARCHAR(20)
)

INSERT INTO @Heroes ( [Heroes_ID], [Heroes_Name] )
VALUES ( 1,'Superman' ), ( 2,'Batman' ), (3,'Ironman'), (4,'Wolverine')

SELECT * FROM @Heroes

SELECT STUFF((SELECT ', ' + [Heroes_Name]
			  FROM @Heroes
			  ORDER BY [Heroes_Name]
			  FOR XML PATH('')), 1, 1, '') AS [Output]
