Haruo Sakaki is the main protagonist in the Godzilla anime trilogy. He is bent on killing Godzilla after mankind was driven of the planet Earth.

Origins
When he was only four years old, his parents were killed by Godzilla. Since the evacuation of Earth, he desired revenge against Godzilla.

Godzilla: Planet of the Monsters
At the beginning of the film, Haruo is threatening to destroy a landing shuttle when the Committee plan to send the elderly on to the now inhospitable Tau Ie. However, he eventually is arrested, and thrown in prison, left to watch in anger and sadness as the landing shuttle with all the elderly people explode before his eyes.

Some time later, Metphies comes in to smuggle Haruo the classified data on Godzilla. This Haruo uses to make an anonymous thesis on how kill the monster. When the Committee members make the choice to return to Earth, and find Godzilla still alive, Metphies calls for Haruo’s release. Now on bail, he explains the attack strategy, An day calls for 600 men to go down to Earth.

When the crew go down to Earth and set up camp, Haruo goes with Dr. Martin on the investigation. Colonel Leland sends Yuko Tani with Captain Sakaki to watch him. In the forests, he and Yuko Tani talk. Dr Martin’s assistant finds ruins of Earth buildings. Seeing this, Haruo falls on his knees, and promises that they will take Earth back.

When a swarm of Servum attack the camp, Haruo and the rest of Thebes investigation crew urgently return to camp to see what is happening.

After the attack, Colonel Leland orders that the team must retreat and headbands back to the Aratrum. Haruo is angered by this, for he wants their true home back. Regardless, the attempt a return to the Aratrum through Tanzawa Pass.

However, what they think is the full on Godzilla appears, and attack should the shuttle. Haruo ejects from the ship on a hover bike, and attacks Godzilla to try and get a recording of the shield generation. However, Colonel Leland does this, and dies.

Though Metphies was going to receive the position, he passed it on to Captain Sakaki. He leads the group in an attack. Though many die, he, Yuko, and other power suit operators are able to force EMP probes into Godzilla, destroying it.

However, in the aftermath of the battle, Dr Martin tells him his fears that the one they killed was merely a cell relative. The original Godzilla emerged from the mountain, confirming this fear, and was massive after 20,000 years of rest. Haruo attempts to distract Godzilla so the others can escape, but Godzilla shoots all of them down, with Haruo included.

He wakes up in a hut, with a tribal girl tending to him.

Godzilla: City on the Edge of Battle
Haruo Sakaki returns to fight Godzilla in this sequel.

Personality
Haruo seems to care very deeply for human life, as shown when he attempted to stop the emigration to Tau Ie, for he knew it was wrong to kill abandon people. While he feels contempt towards men like those in the Committee for how they tried to sacrifice the elderly, he also feels guilty for his contempt towards them, understanding that most people in that situation of decreasing supplies would do something like that.

He feels a deep desire for vengeance against Godzilla, and a deep desire to reclaim Earth from Godzilla.
