Lance Sterling

Walter is socially awkward and lacks charm—he's very awkward around people he meets. However, he compensates for this with intelligence and creativity.

He's gifted in science and has a strange obsession with pigeons (and, to a lesser extent, Korean pop culture). He expresses his knowledge of pigeons through random pigeon facts. He has odd ideas when it comes to inventions, which often leads others to consider him "weird."

Walter is a natural-born pacifist. He deeply believes that violence is never the answer, and all his gadgets are designed to be as safe as possible while still being effective. His moral compass and refusal to harm others stem from the grief of his mother's death in a shootout where she saved many lives.

Walter is naive, good-natured, serious, stupid, nervous, enthusiastic, considerate, thoughtful, kind, selfless, highly intelligent, honest and gentle.

Appearance

Walter is a short, slender, fair-skinned young man with wavy brown hair and blue eyes. He stands 5 feet 6 inches (about 168 centimeters) tall.

He wears:

yellow zip-up hoodie;
an untucked green checkered shirt with long sleeves;
brown trousers;
Red and white low top sneakers with white stripes on the sides.
On his left wrist, he wears a smartwatch projector with a black and maroon band. His maroon backpack functions as a mobile laboratory, allowing him to carry his experiments and inventions with him. Later, the backpack receives an upgrade—miniature rocket boosters, turning it into a jetpack.

Walter was born on February 12, 1999, and his zodiac sign is Aquarius. He suffers from motion sickness.

Overconfidence and arrogance. At the beginning of the film, he has a huge ego and believes he's the best spy, capable of solving all problems single-handedly. He fires Walter Beckett for including one of his gadgets in a mission, despite its effectiveness.
The habit of solving problems using physical force and violence.

Dislike of people. He often prefers to work alone and rejects anyone's help.

Control freak. Lance repeatedly orders Walter to create an antidote, attempts to control a flock of pigeons, and demands Walter hand over his technology shortly after firing him.

Rageous motivation. Many of his behaviors and refusal to work as a team stem not from arrogance, but from guilt after seeing innocent people die in the line of duty because of his actions. Lance doesn't want others to be put in danger because of his actions.

Cheerful and enthusiastic. He embraces the opportunity to apply his intelligence to good causes and contribute to a common cause.

The ability to reinvent himself. Spending time with Walter helps Lance overcome some of his character traits, and he eventually sees Walter as an invaluable ally and best friend.
