The Iron Giant is a massive robotic behemoth, appearing in the 1999 film of the same name.
The Iron Giant is a huge humanoid behemoth, that's at least 50 feet tall. This advance machine is capable of devouring metallic items and converting it into fuel. Its eyes are capable of shooting lasers. In addition its capable of flight. It possesses another form that is armored and bristled with laser weapons, which possibly hints that it was originally a war mech of some kind. The machine has a strong amount of endurance as it was able to survive a nuclear missile at point range, with only it pieces scattered about the planet. The pieces are capable of reorganizing themselves and self-repair.
In the film, the Iron Giant appears in Aech's garage under construction, and is later used during the final battle for the OASIS. The giant is initially very effective during the battle, destroying many Sixers and IOI tanks with both its fists, feet and lazer weapons. When Mechagodzilla emerges onto the battlefield, the Giant immediately charges Mechagodzilla and blasts it with several bursts from its hand cannon. However, this has little effect, and it is quickly overpowered by the larger and more powerful Mechagodzilla, quickly being knocked down and then being heavily damaged by a burst of Mechagodzilla's atomic breath in the back. After Mechagodzilla is distracted by the arrival of Daito in a GUNDAM armor, the giant saves Parcival and Sho by leaping on the monster's back and pummeling its head, before placing Artemis on the creature's head, allowing her to deliver the final blow and destroy it. Soon after, the giant sacrifices itself to serve as a bridge to allow the remaining members of the High-5 into the castle, sinking into the lava while giving a thumbs-up, a reference to Terminator 2, Judgement Day.
- When the Giant was first confirmed to be in the film, a controversy arose when many fans noted that the Giant was depicted in the promotional trailers as a weapon of war, which they claimed was a contradiction to the original 1999 film's Giant, who was a pacifist and despised violence.
- Notably, the Giant does not take on the full-weapons form that he used in the original 1999 film against the Army during the OASIS battle. However, when the Giant attacks Mechagodzilla, its eyes turn red for a brief second as it activates its arm cannon. Thus, it is likely that Aech could have accessed the rest of the Giant's weapons and assume the weapons form, but had simply chosen not to.
