Olg (Total War)

Olg was a Shadow Bloat, raised by the Prince Zant since he was a bug. He is known to attack and eat people.

The Realm of Twilight
Olg was raised by Zant since he was a child. For some reason, Olg lives far longer than most other male Shadow Bloats, who die soon after maturity.

One day the Twili worker Midna takes a stroll around a garden. Unbeknownst to her she was being stalked by Olg. Olg jumps at her, startling her and attempts to eat her, but Zant steps in and scolds him, stating that it was rude to disembowel people.

After the three Great Fairies of Twilight Veran, Morsheen and Una kill Zant's father and puts Midna instead of him, he begins to use Olg to breed an army of Shadow Insects to rebel against Midna.

Olg assists Zant in his rebellion to regain the throne.
