Big D (Sammy & Co)

"Whaaat? I–I–I said they'd get out! They got out! Not my problem."

- Big D, clearly uncaring that the two manta rays in his so-called "escape plan" were eaten alive by barracudas.

Big D is a character in the Sammy & Co series, appearing as the main antagonist in the film A Turtle's Tale 2: Sammy's Escape from Paradise in the A Turtle's Tale duology. He was the tyrannical leader of all the sealife in "the Tank", the largest aquarium in the world. He is also Sammy and Ray's archenemy during the events of the film.

He is voiced by Carlos Alazraqui.

Personality
Big D is a selfish tyrant who has no regard for other lives, and rules the Tank with an iron fist with propaganda about himself attempting to rescue the other marine life from the Tank through his so-called "escape plan". This is shown when he trapped his cousin, Tremaine, in an ice cube for a petty excuse about the latter talking about him being no better in the past than he is in the present, instead of feeling remorse for his actions. He also loses his anger easily, as shown when things don't go his way, he subjects other to extreme punishments.

It's later revealed that he doesn't truly want to leave the Tank, which shows that he enjoys being an evil tyrant who does horrific things, which also makes him a sadist. After he is shunned by the other marine life so they can escape the Tank with Sammy's help, two fish decide to keep living in the Tank as they actually enjoy it, showing that if not for Big D's tyranny, the Tank would be a safe haven for marine life to live. In the end of the movie, he is later trapped in a fishbowl, thus getting what he deserves.
