Sokudo Yudin is a character who appears in Taylor Gorrell's fanfiction, Yu-Gi-Oh! GSTART. He is Kohaku Yudin's only brother.


Sokudo has thick cobalt blue hair arranged in slicked back spikes, and the same cyber green eyes as his brother. He typically wears a tan-colored t-shirt with a blue collar, blue shorts, and red sneakers with white trim.


"Sokudo" means "speed", a reference to his hobby and his design basis.


Sokudo is the calmer of the two Yudin twins, but he still enjoys having fun. He likes going fast, claiming he likes the feel of the wind in his hair. Sokudo is smart for his age, much like Kinoko, from a combo of his parents' and Kohaku's support.


Coming soon...


Kohaku Yudin

Sokudo shares a strong bond with Kohaku, being his only brother. The two often play with each other and practice their Dueling, and Kohaku helped him pick out his Deck.

Kinoko Yudin

Being twins, Sokudo and Kinoko share a very close bond, even closer than Sokudo's bond with Kohaku. However, Sokudo is often annoyed at Kinoko's recklessness.

Hakaimo Yudin

Like Kohaku and Kinoko, Sokudo enjoys watching Hakaimo while she's either asleep or awake. Hakaimo clearly knows who Sokudo is, smiling when she sees him.


  • Sokudo's design and name are based off of video game character Sonic the Hedgehog, with Sokudo's hair being identical in appearance to Sonic's quills.
  • Kinoko and Sokudo's birthday, May 8th, is also Taylor Gorrell's birthday.


Sokudo's Deck is a Needle-themed Deck, a theme that surprised even Kohaku. His Needle Burrower scares Kohaku, due to his fear of scorpions.
