Apache Kid

He is unaffected by Diamond cards played on him.

A character I like very much. He is strong, plus he is an excellent example of how seemingly unimportant details (such as all the Indians cards and half the BANG cards being of Diamonds) can be used effectively while designing an expansion for the game.

Belle Star

During his turn, cards in play in front of other players have no effect.

Bill Noface

Draw 1 cards, plus 1 card for each wound he has. 

Chuck Wengam

During his turn he may lose 1 life point to draw 2 cards from the deck.

Very funny to play and to see being played! I know players who cannot resist but losing all life points except the last one to draw all possible cards from the deck!

Doc Holyday

During his turn he may discard once two cards to play a BANG!

Elena Fuente

She may play any card as if it was a Missed!

Greg Digger

Each time a character is eliminated, he regains 2 life points.

Herb Hunter

Each time a character is eliminated, he draws 2 extra cards.

José Delgado

Twice in his turn, he may discard a blue card from the hand to draw 2 cards from the deck.

Character by Giovanni Ottieri.
In the 1st edition of the expansion he may use his ability as long as he wished: however, sometimes this proved to be excessive.
 

Molly Stark

As soon as she plays a card outside his turn, he draws a card from the deck.

Pat Brennan

Instead of drawing normally, he may draw a card in play in front of any one player.
 

Pixie Pete

Draws 3 cards instead of 2.

In the original version he draws 4 cards: definitely too much!

Sean Mallory

He may stay with 10 cards in his hand.

The original edition had no limit to the cards in his hand: but this may lead to situations where the player keeps accumuating cards in his hand, up to 20 and more, slowly waiting for a Volcanic to unleash a deadly combination!

Tequila Joe

When he plays a Beer, he regains 2 life points.

Vera Custer

For a whole round, she has the same ability of another character still in play.
