Mama Bear

The Leader is an android, and the secondary antagonist of Toybots.

She returns as Mama Bear in Beary Emporium

History
LB-529 was a regular factory droid. One day, she developed sentience. Dissatisfied with the conditions at the factory, she, and a band of other robots revolt against their human masters, taking over the factory and enslaving the humans.

She becomes the leader of the androids, and forces the humans into hard, life threatening labor.

Eventually though, her second in command (nicknamed Mini), incapacitated her in a bid for power. A few days later, a wounded Standard nursed her back to health, the beginning of a friendship that would eventually blossom into something greater.

LB-529 returns just as "Mini" is about to kill the person she hates the most (Toybot's protagonist). She intervenes, and punches Mini's face out. Afterwards, she orders the person to go to her office.

In the office, she gloats as she says that the person will be work for her for the rest of their life. However, before she can electrocute the person, the factory is bombed, and she is buried under rubble.

Decades later, some construction occurs, and she is presumed to have been uncovered.

At the time of Beary Emporium, LB-529 (Nicknamed Mama Bear), is the mascot of a "mall", and is in a close relationship with Standard (Papa Bear).

Mini
The Leader and Mini do not get along. Both view each other as obstacles to their power. The Leader is above Mini in command, and is also much more powerful, which really isn't saying much.

Standard
Standard clearly looks up to his Leader. As of now, her views on him are unknown.

Brute
The Leader and the Brute have not interacted yet. As of now, their relation is unknown.

Generic Robots/The Hive
As stated, the Leader is, well, the Leader, and commands the hive. The hive follows orders from her. Her view of them though, is currently unknown.

Unknown Protagonist
Though the Leader hates all humans, she has a particular hatred towards our protagonist, implying that they have a bad history.

Personality
The Leader is shown to be rather chipper, though rather insincerely.

She likes to be in control, reveling at having power over others.

Like most of the other members of the Endo Gang, the Leader is extremely misanthropic. She considers killing humans "fun".

She is also tends to be very sarcastic.

In many ways, her personality is similar to that of Mini, which is a huge reason why they do not get along.

Gameplay
Unlike the rest of the Endo Gang, the Leader does not have a gameplay segment, though her voice can be heard in the first and second night, and she appears at the end of the fifth.
