Pooh's Adventures of Pacific Rim is an upcoming Winnie the Pooh crossover by N/A.
In 2013, an interdimensional portal, the Breach, is opened in the Pacific Ocean by extraterrestrials, who send giant monsters called Kaiju to attack cities on the Pacific Rim. To counter the attacks, the United Nations funded the Jaeger Program, constructing giant mecha robots which are controlled by two or more pilots, who are mentally linked via “drifting” to carry the heavy mental and psychological load of operating the machines. In 2020, pilots Raleigh and Yancy Becket are assigned to protect the Alaskan coastline, but take their Jaeger, Gipsy Danger, to rescue a fishing boat from a Kaiju. However, the Kaiju blindsides the Jaeger, ultimately wrecking it and killing Yancy. Raleigh single-handedly pilots Gipsy Danger to shore after killing the Kaiju, but quits the program, traumatised by Yancy’s death.
By 2025, world leaders decide to shut down the Jaeger Program due to the increasing number of Kaiju emerging from the Breach, and opt to construct giant defensive coastal walls instead. Marshall Stacker Pentecost, commander of the Jaegers, plans to launch a final assault on the Breach with a nuclear bomb. He tracks down Raleigh and recruits him back into the program to help with the attack. At the Hong Kong base, Raleigh meets the crews for the remaining Jaegers, and Pentecost’s adopted daughter Mako Mori, who shows great potential as a pilot, but Pentecost refuses to let her drift with Raleigh until convinced otherwise. However, when Raleigh briefly falls out of synch during the drifting process, Mako becomes lost in her childhood memory of a Kaiju’s attack on Tokyo, and nearly activates Gipsy Danger’s plasma cannon until the Jaeger is shut down.
Pentecost grounds Raleigh and Mako. Meanwhile, scientist Newton Geiszler creates a device that allows him to drift with a Kaiju’s brain, discovering the Kaiju are bioweapons and their creators' plot to wipe out humanity. In order to obtain another Kaiju brain for Newton to drift again, Pentecost sends him to find Kaiju black market dealer Hannibal Chau, who operates within Hong Kong. However, Newton’s actions cause two Kaiju to be unleashed on the city. The Jaegers, Crimson Typhoon, Cherno Alpha, and Striker Eureka, are sent to slay the Kaiju, but the first two are destroyed while Striker is immobilised by an EMP blast. Out of options, Pentecost allows Raleigh and Mako to pilot Gipsy Danger to rescue them, and the two pilots successfully kill both Kaiju. Newton and Hannibal go to retrieve the Kaiju’s brain but discover it is pregnant. The infant eats Hannibal but is strangled by its own umbilical cord, allowing Newton and his partner Hermann Gottlieb to drift together. They discover that only the Kaiju can travel through the Breach and immediately proceed to warn Pentecost and the Jaeger team.
Pentecost, who reveals to Raleigh he is terminally ill due to piloting a nuclear-powered first generation Jaeger, decides to push ahead with his original plan. Pentecost and Chuck Hansen pilot Striker Eureka and accompany Gipsy Danger to the Breach, encountering three Kaiju, including the biggest they have seen. Both Jaegers are severely damaged in the battle. Striker Eureka carried a nuclear warhead intended for the Breach, but Pentecost and Chuck decide to to clear the way for Gipsy Danger by detonating it to kill two of the Kaiju. Gipsy Danger will serve as an improvised bomb since it is powered by a nuclear reactor. Gipsy Danger kills the surviving Kaiju and rides its body through the Breach ino the alien dimension. With their oxygen levels dropping, Raleigh ejects Mako’s escape pod and manually overloads the Jaeger’s reactor before escaping himself. The Jaeger explodes, destroying the aliens and sealing the Breach. Raleigh and Mako surface in the Pacific Ocean and embrace for their victory.
In a mid-credits scene, Hannibal is revealed to have survived and cuts his way out of the dead infant Kaiju.
