Platinum

"Those pigs... They've torn my soul to tatters. *sniff* I didn't want to do anything for them, and they decide to force me to make robots for them... I... I'm helpless! *sniff*"

- Platinum, to herself It's easy to guess why she's acting this way: The pigs kidnapped her, and forced her to make them a bunch of robots that look identical to her. This moment in life just scared her to death!

Looks
She looks identical to Silver, save for the slight blue tinge, eye color, and cybernetic eye. Her size is comparatively larger than her daughter's, and she seems to be a little more square in appearance.

Personality
Usually, she's a fun loving bird, having an interest in Robotics, easily able to make friends, and knowing how to turn the situation into a weapon when those pigs are around...

...But recently, she became scared for her life, being timid and afraid of those that she thought were merely stupid and harmless. She, noticing that Silver was raised by the pigs 3 years before she first found her, looks out for her, and would care for her the best she can.

Angry birds(Probably)
Silver appears in the original timeline, but Platinum doesn't. The only good explanation would be that She died before Silver hatched.

Angry birds: Revenge taken/Starstorm
She never appears in Revenge taken, but appears in the Animated series, and the game's sequel.

(TBA)

Ability
Her ability involves deploying two sentry gunner drones, which will aim at nearby pigs and shoot them, much like how they did in Angry birds Star wars II.

This can be useful when the player has to mow down a pig defense, but using a short supply of birds. Although eachnsentry blast can take out one ice block, they can do enough damage to dislodge a wood block in a couple of shots.

Trivia

 * This character is slightly based off of Silver herself, so anyone could assume that Silver is her mother.
 * However, this has been proven false by her creator.
 * Her personality is similar to that of a person who just survived a serious ambush.
 * Her ability is a boosted version of the one from Angry birds Star wars II.
