From Bulbapedia, the community-driven Pokémon encyclopedia.
Isaac (Japanese: イオリ Iori) is a character in Pokémon Ranger: Shadows of Almia. He is a young scientist, who graduates from the Ranger School with the player and gets to say the graduation word.
He belonged to Mr. Kincaid's class in the school, where he was allowed to go off to the library to learn on his own due to his IQ of 163. He is next seen with Mr. Kincaid doing an experiment in his secret basement laboratory. After graduation, he went to Pueltown with his sister, Melody. He seemed to do 8-digit multiplications easily in his mind, which is quite abnormal for an average human. He is also known for his mushroom-like hairstyle.
He worked for Altru Inc. after graduation. When they first arrive to his place of work, he shows the player and Murph around the building. He then leaves with Blake Hall for work.
He was briefly mentioned when Kincaid was boasting about the Miniremo units, in which Kincaid describes him as a little boy, who has intelligence that appears once in a century. He is later seen working for Team Dim Sun under false promises that their machines make Pokémon and people friends. During his stay with Team Dim Sun, he apparently taught the Sinis Trio basic programming. A Dim Sun minion can be seen singing the Miniremo production song, he mentioned "The creator of this thing is no hack.. His name rhymes and it is... Whoa! A Ranger?" Isaac's name rhymes with the word 'hack'.
He did not seem to recognize that Sven considered him a criminal and was happy to see that Sven is going to send him to Professor Hastings. He also attempts to show the player his experiment with Skuntank and also wondered why the player treats Dim Sun Grunts badly. After learning that the Incredible Machine is actually a machine to control the Pokémon of Almia, he gets worried as Team Dim Sun Admins tried to attack him. Fortunately, Sven protects him while the player captures a Gliscor under Kincaid's command.
After that incident, he decides to work at the Ranger Union, when he is offered a deal after telling them the Incredible Machine's design disc's password. He attends the meeting to reveal that the Altru Tower is the Incredible Machine.
Later, the Sinis Trio attacks the Ranger Union to take him back. While Heath distracts the player with an Electivire to capture, Ice was reminding him of memories of Altru and how they were friends; however Isaac refused, which forced Lavana to interfere, threatening his sister. Because of this, he goes back to Altru with them under obligation.
He is later seen under pressure from Dim Sun admins programming the Incredible Machine. When the player arrives to this scene, they are eventually tasked to capture Pokémon under their command. Nevertheless, when the player arrives to stop Isaac, it was too late since he has finished the "wicked" program. He accompanies the player to destroy the barriers created by Team Dim Sun by disassembling the program to allow the player to perform a Target Clear, notably disassembling in 1.3 and 1.2 seconds Heath and Lavana's programs, respectively. However, he is trapped in a barrier created by Ice. In the end, Barlow manages to free him by damaging the generator using his "Trademark Field Move".
Isaac's sister, Melody, currently lives with their grandparents and a Buneary in a house in Pueltown. As he is busy with his work, he cannot spend much time with her. However, he loves his sister very much. Her name is Issac's password in Altru Building's elevator, as well as the Incredible Machine's design disc. At the end of the game, he gets a day off and plays the whole day with his sister. There is also an optional quest to help Melody gather singing Pokémon to help her sing a song for Isaac. She is also a reason for Isaac's return to work on the Incredible Machine since Lavana threatened to hurt Melody.
Buneary: Isaac lives with this Buneary in Pueltown.
- Isaac's English name may come from the scientist Isaac Newton.
- Both his IQ and his height, in centimeters, are 163.
- Besides science, a hobby of Isaac's appears to be watching soccer. The television in his family's Pueltown home is noted for being good to watch soccer with.
