Go Shijima

"Let's Henshin!"

- Go's transformation call as Mach

"Searching... destroying... both done, at mach speed! Kamen Rider... Mach!"

- Go's introduction

Go Shijima (詩島 剛) is a freelance photographer and like Shinnosuke, he is the Kamen Rider stationed in America. Go utilizes Signal Bikes, similar to Shift Cars, to transform into Kamen Rider Mach (仮面ライダーマッハ). He returns to Japan to aid with the emerging Roidmude crisis.

He is also Kiriko Shijima's younger brother.

History
Mach is first seen visiting the Drive Pit on his own, speaking to Mr Belt. Later, when his older sister gets attacked by an evolved Volt Roidmude, he counter attacks him, leaving shortly after Shinnosuke comes to help her.

Personality
Go has a very impulsive and outgoing personality, whose hyperactivity may have worsened during his time in America. He is also very intelligent, which coupled with his robust physique, makes him a very capable detective. He is also pretty competitive, as seen with him challenging Shinnosuke to find and finish Gunman.

He has a flair for drama and also quite the jester. Despite being entirely capable of subtlety, he prefers to make his entrance in a proud, flashy manner, going so far as to call his sister to his debut battle in Japan, just so that she can witness how cool he is. These traits ultimately resulted in him liking to rush into dangers.

For all of his bluster, however, Go does have a serious side. Due to the fact that both the Kamen Riders and the Roidmudes use Core Driviars as the source of their powers, he considers himself just as much of a monster as the ones they fight.

Powers and Abilities

 * Peak Human Physicality:
 * He has a very athletic physique - a trait he shares with his sister. He easily demonstrates acrobatics way above that of average human's, shown to be able to somersault over tall walls, hand-standing, jumping from a tall tower to a roof over a great distance, then landing safely on his bike.


 * 4th Wall Awareness:
 * Currently, he can comically see and interact with Shinnosuke's imaginations, which are supposed to be seen by the viewers only.

Family

 * Kiriko Shijima - older sister

Forms
Some Signal Bikes alter the suit based on a certain attribute, whereas other Signal Bikes arm Mach with a certain element or weapon, by changing the signal on Mach's suit for a Signal Exchange (シグナル交換). These two types of Signal Bikes can be used in conjunction with each other.
