Affiliation: Rapid Tribe Vehicle: Sports Car Metal Cards: Sonic Runner Color: Yellow Orange First Appearance: A Lucky Person Who Knows How To Have Fun Voice Actor: 🇰🇷 Yang Jeong-hwa Tachy is a yellow Cardbot with a cheetah motif, notably her helmet, black spots and a cheetah tail, light-blue distinctive hexagonal eyes with a unique frame, a track runner appearance, white sections on the arms, torso and upper legs, orange sections on the limbs and torso, a back unit comprised of her vehicle form's hood, and a zig-zag arrow symbol on each side of the head. Her vehicle form is a sports car with a cheetah face on the roof. Metal Card - Sonic Runner (메탈카드 - 소닉 러너, Metal Kadeu - Sonig Leoneo): A pair of cheetah-style armored leg extensions. Gauntlets: Tachy wields a pair of cheetah-based claw gauntlets formed from her vehicle form's front end and wheels. Originally stored on the back unit Tachy's name is a fusion of the anagram form of "cheetah" in Korean, and the prefix of "tachyon", a hypothetical particle that always travels faster than the speed of light. Due to her appearance, Tachy is the first official female Cardbot in the series. Tachy's design is based on track and field athletes, and one character from two different franchises: Arcee from Transformers in certain parts of the transformation (the back of the vehicle forming the upper legs and the front of the vehicle essentially resting on the back untouched). The head is based on the character Na-aeri (나애리) from the South Korean sports comic Run Hani (달려라 하니). Tachy is the second Cardbot after Red Blitz to have Metal Card weapon augmentations for the legs.
