The Golden Digimentals, and is a from Summer Memory, Colorado who has two Digimon partners,  and. However, Kokomon disappeared when he was a child, and eventually began to violently chase Willis.

Description
While the egg that hatched into Botamon appeared before Tai and Kari in Japan, in America, a single Digi-egg hatched into Gummymon and Kokomon for Willis. He bonded with his new friends, who helped him do his chores.

Willis, unknown to anyone, thought it would be great to have more Digimon friends and tried to create another Digi-Egg on his computer but in the process it is attacked by a virus. Koushiro "Izzy" Izumi discovers the on the internet infecting Willis's DigiEgg. At the same time, Taichi "Tai" Kamiya is trying to apologize to Sora Takenouchi for getting her a hairclip for her birthday in an e-mail. Izzy arrives at Tai's house out of breath, telling Tai about the newly-hatched. Tai and Izzy use Tai's dad's computer and monitor the Digimon until Gennai appears in a transmission from the. He sends and  to help stop the corrupted Digimon. They put up a good fight until digivolves to  and defeats them. Tai tries furiously to contact and alert the rest of the DigiDestined and ends up getting only Yamato "Matt" Ishida and his brother Takeru "T.K." Takaishi. They find a computer in a barber shop and upload and  onto the net. Infermon Digivolves to after Agumon and Gabumon Warp Digivolve to  and  but then they slow down because of the massive amount of e-mails being sent to Tai and Izzy. Tai slaps the computer and freezes it leaving WarGreymon frozen and defeated. Diaboromon then starts multiplying and sets up a timer for 10 minutes as he forces the Pentagon to launch two nuclear missiles: one headed for Colorado, the other for Tai's neighborhood. WarGreymon and MetalGarurumon wake up and race to defeat Diaboromon, only to find over a million copies of him. Every single copy fires and blast them until they lie defeated. Tai and Matt mysteriously enter their computers and talk to their Digimon. WarGreymon and MetalGarurumon DNA Digivolve to who easily defeats all but one Diaboromon. At one minute to go, Diaboromon is still too fast for them to hit, but then Izzy forwards him the e-mails, slowing him like it did to the other Digimon. At the very last second, Diaboromon is destroyed, disabling the missiles. But the virus tracks down Willis and infects Kokomon.

While Izzy does mention an online friend who takes college courses despite being in elementary school helping him with aspects of the battle, Willis has no bearing on the Japanese version of "Our War Game." His presence in the dub was added to connect it to the events of "Digimon Hurricane Touchdown" and "Supreme Evolution! The Golden Digimentals," thereby creating one story within the movie.

T.K. and Hikari "Kari" Kamiya are in taking a picture but are having trouble then Kari senses something. The attention turns to Willis and Terriermon, who engages in a battle with Wendigomon, who keeps telling Willis to "Go back," and loses. Willis and Terriermon journey to Colorado while Kari e-mails Davis Motomiya to inform him of Willis. After taking planes and taxis, they end up meeting Willis in a truck while Kari and T.K. literally get derailed by Wendigomon, who demands that they "don't interfere," just like Diaboromon. Willis tries to get Davis, Yolei Inoue and Cody Hida a lift to his house (in the form of a pizza truck). The ride leaves without Willis and Davis, who encounter Wendigomon which leads to a battle between him, Flamedramon and Gargomon, Terriermon's Champion form. Before anyone is defeated, Wendigomon disappears, repeating his cryptic message, "go back." As they all need a ride, Veemon digivolves to Raidramon and carries the group to the others.

Davis and Willis meet up with Yolei and Cody who told Davis that Kari And T.K. aren't here (to Davis's disappointment). Willis doubts that they'll come at all if Wendigomon interfered. After the kids question his knowledge about Wendigomon, Willis reveals he created him but regrets saying so and storms off, while being followed by Davis. Willis reveals the story about Wendigomon, how he became infected and reveals that he was the one who created Diaboromon. Davis offers to help with the rest of the kids and their Digimon. Terriermon overhears the conversation (blaming it on his "really big ears") and offers to help. Willis refuses his help out of concern for his safety but Terriermon talks him into letting him. At Willis's lake, Wendigomon reappears, as expected, but digivolves to. He swiftly evades the attacks of Gargomon, Flamedramon, Halsemon and Digmon and throws all the Digimon around like rag dolls. Antylamon sinks into the lake (and changes the scenery), and rises again, but as Cherubimon. He then de-digivolves all the Digimon. However, they still try to fight, but to no avail, as Kerpymon grabs them and is about to eat them when Angemon and Angewomon cut off his arms and T.K. and Kari show up.

Cherubimon changes the scenery again and de-ages the Digidstined, revealing that he wanted Willis to "Go back" in time to when the virus attacked him. Angewomon and Angemon digivolve to their Mega forms, and, to release two Golden Digi-Eggs (the Digi-Eggs of Miracles and Destiny for Willis and Davis). and Terriermon Golden Armor Digivolve to and Rapidmon (Armor), who get sucked into Kerpymon. Inside they see Wendigomon who tells them to destroy the virus. Doing so purifies Kerpymon, transforming him into his vaccine form, who soon dies. After saying goodbye to his new friends, Willis and Terriermon walk back home, and notice the Digi-Egg that will hatch into Conomon, Kokomon's Fresh form. In the movie's final scene, it shows him with Lopmon.

Willis was able to communicate with the DigiDestined because a Japanese girlfriend taught him. He is especially friendly to girls and flirts with them (preferably Yolei); on the other hand, he is the exact opposite towards Davis Motomiya. While Willis considered Davis strange and rude, Davis found Willis arrogant, which struck a friction between the boys. When Willis revealed how he did not have the heart to fight Kokomon, Davis sympathized with him and promised to fight for him. Although Willis and Davis become friends, there are still points at time where Willis would mock him.

Right before Willis leaves, he makes Davis jealous by kissing Kari and Yolei on the cheek before running away.

One year later, Mimi Tachikawa invites both Willis and Davis Motomiya for a summer vacation. While Davis is still mourning over his love life and loss from a soccer match, Willis arrogantly scolds him to get over it. It is also revealed here that Lopmon was not reborn, something that makes Terriermon sad when reminded. When an unsuspecting winter falls, Willis suspects that it may have been spawned from Davis' heart regarding Davis' foul mood. As soon as Nat-chan appears, Willis is astounded that she preferred Davis over him. Nat-chan becomes jealous of Gummymon and for having partners and soon reveals herself to be a Digimon. While Willis tries to beg Davis to escape before Nat-chan attacks, to his amazement, Davis manages to heal Nat-chan. As soon as the winter dissolves, Willis and the others attempt to find Nat-chan a partner; however, the summer heat becomes too unbearable for them. When part of the group express their disgust for the heat, Willis, annoyed, tells them to stop talking.

In August 2010, Willis is one of the many DigiDestined that has their mind seized by and interred within the Netherworld so that he can live within his memories with Terriermon and Lopmon. After and  destroy the combined Eosmon's Mega form, Willis is freed and regains consciousness in the Real World and plays with Terriermon and Lopmon— who had been reborn at some point— on the beach.
