Wilbur Robinson is the 13-year-old son of Cornelius, a.k.a. Lewis, and Franny Robinson, and the central protagonist of Meet the Robinsons and the main protagonist of the video game of the same, which takes before the events of the movie.
He was voiced by Wesley Singerman. In the Japanese dub from the movie, he was voiced by Hiroyuki Yoshino.
Though Wilbur often finds himself in trouble, he always thinks of the way to get himself out of it. Impatient, Wilbur often acts quickly and during his time travels, uses stealth and generally acts in the manner of his fake persona as a "Time Continuum Task Force" officer until Lewis sees through his facade. Wilbur generally acts very confident, but he is rather careful about trying to keep Lewis' cover until realizing he can't keep the act up, so he is forced to expose him in front of his family.
Meet the Robinsons
After leaving the garage door open while taking out the trash which allows the Bowler Hat Guy to steal the second time machine, Wilbur follows him through time in the first machine and pulls his future father, Lewis, under a table to warn him about the Bowler Hat Guy, but Lewis thinks he's crazy and leaves.
While looking for the Bowler Hat Guy, Wilbur runs into his future mother Franny and knocks her frogs from her hands then jumps on another kid, believing him to be the Bowler Hat Guy. He watches proudly as Lewis displays his Memory Scanner and is horrified when it goes wrong, spotting Bowler Hat Guy and Doris. He then throws Lewis' designs back at him and pretends to be a pigeon to get his attention. When Lewis doesn't believe him about being a Time Agent, discovering that his "badge" is just a tanning salon coupon, and tears up his Memory Scanner plans, Wilbur makes him a deal: if he can prove to Lewis that he's from the future, then Lewis will fix his Memory Scanner. After getting Lewis' sarcastic agreement, he shoves him off the roof into the time machine and takes him to see the future. Lewis, however, decides to use the machine to stop his mother from abandoning him and the two boys fight over the controls, causing the machine to crash.
Wilbur makes Lewis another deal: fix the time machine and he'll take him back to see his mother, though he has no plans to actually do so. He hides Lewis in the garage, he makes him wear a fruit hat and warns him not leave. Wilbur gets the plans to the time machine from a panicking Carl who reveals that if he fails there's a good chance he won't even exist.
When Wilbur returns to the garage, he finds Lewis is disappeared and frantically searches the house for him, before the two literally run into each other after Lewis meets Wilbur's family, which horrifies him. Wilbur quizzes Lewis on what he knows of his family, telling him that his father looks like Tom Selleck. Wilbur watches as Lewis tries to fix the time machine and explains the history of it, his father's inventions and the motto "Keep Moving Forward," also giving him a hat with a lightning bolt on it as he can't take Lewis seriously in the fruit hat. Lewis' efforts to fix the time machine fail and Wilbur tries to comfort him, failing and Lewis believes he's no good. As Wilbur tries to put his hand on Lewis' shoulder in comfort, Franny calls them to dinner and Wilbur has no choice but to take Lewis as Franny threatens to come and get them, which would result in her seeing the broken time machine.
At dinner, Wilbur introduces Lewis as an orphan and tries to get him to fix Cornelius' peanut butter and jelly maker to boost his confidence. When the family demands Lewis take off his hat, Wilbur causes a food fight to prevent it. Doris later tries to drop a chandelier on him but is interrupted by Bowler Hat Guy sending in a Mini-Doris controlled dinosaur named Tiny. Wilbur and his family battle to protect Lewis with Wilbur pulling him out of the way of Tiny, but when he notices Mini-Doris, Tiny tries to eat him on Bowler Hat Guy's orders, but Lewis saves him. Finally, Wilbur defeats Tiny by shooting Mini-Doris off his head with Gaston's Meatball Cannon, rendering Tiny harmless.
Afterwards, he and Lewis share a moment of triumph where the two realize how great a team they make before Lewis accidentally calls Franny "Mom" and she offers to adopt him. Knowing this can't happen and seeing no other choice, Wilbur knocks off Lewis' hat, exposing his identity to the shocked Robinsons, forcing Franny to retract her offer. When Lewis tries to defend him and asks if he can still go see his mom like Wilbur promised, Wilbur blurts out he never meant it while trying to escape trouble leaving Lewis infuriated and feeling betrayed as he'd come to see Wilbur as his friend. Lewis runs off and Wilbur calls after him to come back and that they are friends. For his actions, Franny promises Wilbur that he's grounded until he dies.
Wilbur tries to catch up to Lewis and finds him being enticed by Bowler Hat Guy who he leaves with. Wilbur catches up with the help of Carl and gains Lewis' attention by pretending to be a pigeon again. Carl and Wilbur rescue Lewis who punches Wilbur in the arm for forgetting to close the garage door and lying to him, revealing that he now knows the truth about everything, including being Wilbur's father. Wilbur considers it a great story for Lewis to tell him one day, but before they can reach the Robinson house, Doris attacks, destroying Carl and taking the Memory Scanner. Wilbur is erased from existence, but before that, begs Lewis to fix the time machine and set everything right, expressing faith in him and calling him "Dad." Lewis succeeds in fixing the time machine and destroys Doris, fixing the future, causing Wilbur to return to existence. Wilbur congratulates Lewis before noticing the now-reformed Bowler Hat Guy and attacks him, telling Lewis to run for help. Lewis instead convinces him to offer for the Robinsons to adopt him, but Bowler Hat Guy leaves as they talk, leaving behind his notebook.
Wilbur reunites with his relieved family before his dad arrives home demanding to know about the disappeared time machines and his past self being in the future. Wilbur quickly tries to run but is ratted out by Franny which he finds harsh. After Lewis is shown his future inventions by Cornelius, Wilbur prepares to take him home, waiting impatiently while he says goodbye and reminding him that he will see the Robinsons again as they are his family. Despite his earlier plans to the contrary, Wilbur takes Lewis back to see his mom like he promised and looks on as Lewis prepares to stop her then changes his mind. Wilbur then takes back Lewis to his own time where Lewis explains that he realized he didn't need his mom, he already has a family, the Robinsons. Wilbur and Lewis hug and Wilbur expresses his surprise that his father ended up becoming his best friend. Wilbur gives Lewis his taped back together Memory Scanner plans and reminds him of his motto before promising to return if anything else gets screwed up. As he leaves, Wilbur sky-writes "See ya later, Dad" with the time machine before returning to the future.
Wilbur is an teenager who has an black hair that points upwards. He also wears a shirt with an lightning bolt and jeans.
