Shingo Suzuki (also known as Compact Giant) is a rival that appears in every installment of the Kaido Battle series. He always drives a Toyota Vitz which was red but now blue since Kaido Battle 2: Chain Reaction. It is said that he is very tall, but he likes to drive compact cars. His windows are always foggy, so he often complains that he can't see. The way he is squished is awkward.
- In Kaido Racer 2 and Tokyo Xtreme Racer DRIFT 2, his nickname is Lil Giant.
