Hiroki (ヒロキ, Known as Jake in the American games and Buzz in the European ones) is Spike's best friend, and usually his biggest rival. He's often unwillingly controlled by Specter ("completely reborn," says Specter). He was supposed to be in the storyline for Ape Escape Million Monkeys, but the cutscene where Team Spike (as a good/right side) or Specter (as a bad/wrong side) encounters him was removed from the game according to the official Ape Escape Million Monkeys website. Instead he is a playable character in Coliseum Mode and Multiplayer mode. In the anime series, He is the son of a rich family and has a huge crush on Natsumi. He carries a picture of her with him and dreams about her nearly every time. He ultimately did a lot of heroic things in the anime to save Natsumi, when he saved Natsumi from the evil gone crazy Pink Monkey in Episode 36 Season 2 (protecting Natsumi from behind, and let Pink Monkey hit him instead). Hiroki will do anything to win Natsumi's heart. He is the Second member of Team Spike.
Jake (when not being controlled by Specter) is a lot like Spike, they both appear to be competitive as they race to the Professor's lab in the opening cutscene of Ape Escape. He also shows that he is strong willed when Jake becomes free from Specter's Control, yet he was taken put under control, which questions if he wanted to be controlled or not. Jake has a completely different personality when he is under the the control of Specter, Jake is very loyal toward him and goes along to try and stop Spike from messing with their plans for world domination.
Jake has blue hair and a pony tail (which gets removed in Ape Escape: On the Loose) and appears to be wearing a tank top and jeans. Jake has red eyes whenever he is under the control of Specter.
Role in Saru Getchu!Edit
In the anime, Saru Getchu! Jake is known as Hiroki. He is from a rich family which he notes in the episode when he comes to the lab with a golden net which looks like a Monkey Net even though it's a fake. Most of the time he is shown attempting to impress Natsumi (Natalie) (as he has a crush on her) and catching monkeys with Kakeru (Spike).
Jake makes a minor appearance as unlockable concept artwork in Ape Escape 2.
Jake makes another brief appearance in Ape Escape 3 along with Spike under Specter TV's control.
Jake also appears in Ape Escape:Pumped and Primed, once again under Specter's control. He challenges Spike, his friends, the monkeys, and the Pipotrons several times on a motorbike. Once the unknown man took over the cyber world, he took control of Jake, giving him a new look, but was soon beaten. After beating the grid core, he rejoined his friends, free from Specter's control and returned to the Professor's lab.
