Behaviour Cards are items in All Star Smashers. You can pick them up and throw them. If it touches an opponent, its colour card will unfold. The affect you will get depends on that character's personal behaviour.
Divine Behaviour cards consist of Gold Cards, which give the opponents 30 second immunity and an extra stock.
Good Behaviour cards consist of (in order of best to worst) Pink, Purple, Blue and Green Cards, which heal the opponent more, the better the card.
Neutral Behaviour cards consist of White and Yellow Cards that do absolutely no affect to the character.
Bad Behaviour Cards consist of Orange, Red, Grey and Brown Cards that pit people onto the ground.
Finally, Black Cards mean absolute dead meat making the opponents burn in a fire causing 80% damage and knocking them down to the ground.
