SELECT characters.name Name,characters.image Image,matchups.char1wins Char1Wins,matchups.char2wins Char2wins,matchups.draws Draws
FROM characters INNER JOIN matchups
ON (char1=6 ) WHERE (  characters.ID = matchups.char2 )

SELECT characters.name Name,characters.image Image,matchups.char1wins Char1Wins,matchups.char2wins Char2wins,matchups.draws Draws
FROM characters INNER JOIN matchups
