History:
(Kid Juggernaut: Marvel's Voices Infinity Comic#3 (fb) - BTS) - Jung-Woo Jin was the son of Jin Moon-Ho, who had become a Juggernaut in service to the mystic principality Cyttorak. Forced to align himself with Japanese imperialists...

(Avengers Academy Marvel's Voices Infinity Comic#38) - Jin Moon-Ho defiantly cracked off a fragment of the Crystal of Cyttorak and gave it to Arnie Roth to give to his wife and son, telling them to remember him as he was, not the monster that had been made of him.

(Kid Juggernaut: Marvel's Voices Infinity Comic#3 (fb) - BTS) - Jin Moon-Ha was dubbed "The Drum" (Taiko, in Japanese) by the Japanese. Eventually, after Jin Moon-Ho refused an order to destroy his home village, Cyttorak empowered Cain Marko to slay and replace Jin Moon-Ho.

(Kid Juggernaut: Marvel's Voices Infinity Comic#3 (fb)) - Jung-Woo was left to live with the legacy of his father's actions. At first he tried to defend his father, but for most Korean, Taiko had been a traitor who had renounced his country and his heritage. His mother held the tearful Jung-Woo as he insisted futilely that his father had had no choice when a man called his father a filthy scum.

Eventually, Jung-Woo avoided anything having to do with his father, and he grew bitter and disillusioned.

(Avengers Academy Marvel's Voices Infinity Comic#38) <Four years after the main story> - Arnie Roth delivered the gem fragment to Mrs. Jin and Jung-Woo Jin in a closed box. When he said that he had been a friend of Mr. Jin's, Jung-Woo called his father a traitor and the shame of their family.

Arnie advised Jung-Woo that a man's story wasn't always told the way it ought to be. He then gave Jung-Woo in the box, telling him that his father had asked him to give it to him, and he told Jung-Woo to open it when he was old enough. Jung-Woo asked what it was, and Arnie told him that it was his father's story.

(Kid Juggernaut: Marvel's Voices Infinity Comic#3 (fb)) - Although obtaining a fragment of the gem that had empowered his father, Jung-Woo kept it in a box and avoided it. He drifted through life, unable to hold a job or find stability and spending most of his time in bars and gambling halls.

Hae-Ran met Jung-Woo while waitressing during college. Although her friends warned her to stay away from him, she could see past his pain and that he had a good heart. When she felt like she had failed an exam, he told her that shew was too smart for that and assured her that she had done well, as always.

After Jung-Woo and Hae-Ran were married and had a son, Joon-Sung-Ah (aka Justin), Jung-Woo continued to got out to bars and stay out late.

(Kid Juggernaut: Marvel's Voices Infinity Comic#1 (fb) - BTS) - At some point, Jung-Woo, Hae-Ran and Justin moved to Vancouver, Canada.

(Kid Juggernaut: Marvel's Voices Infinity Comic#2 (fb)) - When his son, Justin, was 5-years-old, Jung-Woo told him that he and Justin's mother were taking a break and that he was going back to Korea for a bit. jin-jung-woo-kj-haeran

When the young Justin proudly showed him a four-leaf clover, Jung-Woo praised this as an exceptional find. Noting that he got to make a wish, Justin told his father that he wished he would not go back to Korea and that he would stay with his mother and him in Canada. Unable to grant this wish, Jung-Woo promised his son that he would be back.

Jung-Woo remained in Korea for at least 10 years.

(Kid Juggernaut: Marvel's Voices Infinity Comic#3 (fb) - BTS / Kid Juggernaut: Marvel's Voices Infinity Comic#6 (fb) - BTS) - Jung-Woo wrote a letter to Justin, apologizing for not being much of a father and stating that that was one of the many regrets he had in life. He further explained about the gem that had empowered his father, but that he had avoided it his whole life, never trusting himself to bear its power and fearing the same thing would happen to him as did his father; however, he was uncertain whether his life was better for it. He stated that Justin could avoid touching it as he did, or that he could claim its power for himself. He concluded that the right person -- a person stronger and better than he could have ever hoped to be -- could use the power to become something great, and he felt that Justin could be that person.
He put the letter in a box containing many of his person items, including the gem. jin-jung-woo-kj-drink

(Kid Juggernaut: Marvel's Voices Infinity Comic#1 (fb) - BTS) - Seeking to claim the Crimson Ruby of Cyttorak, Malphegor confronted Jung-Woo Jin. Becoming impatient when Jung-Woo tried to keep him from the gem, Malphegor slew him.

(Kid Juggernaut: Marvel's Voices Infinity Comic#1 - BTS) - Cyttorak criticized Malphegor for his impatience but told him he could find the gem with Jung-Woo's son, Justin.

    Hae-Ran informed Justin of his father's death.

(Kid Juggernaut: Marvel's Voices Infinity Comic#2 - BTS) - Hae-Ran told Justin that there was a lot he didn't know about his father, mostly because Jung-Woo had not wanted him to know, but now that he was gone, she felt like he had a right to know. Further noting that it might help Justin to forgive his father, she told Justin she was going to the lawyer's office to settle Jung-Woo's estate, after which she would explain everything, and she advised him to have an open mind.

    Before his mother got back, a package of Justin's father's belongings were delivered to her doughnut shop. As the package was addressed to him, Justin opened it, and after grasping the pendant within, he was granted the power of a Juggernaut.

(Kid Juggernaut: Marvel's Voices Infinity Comic#3 - BTS) - Hae-Ran told Justin of his grandfather, Jin Moon-Ho, and of how she had met Jung-Woo. Eventually, Malphegor confronted them, demanding that Jung-Woo give him the Crystal of Cyttorak or he would kill him, just like he had slain his father.

(Kid Juggernaut: Marvel's Voices Infinity Comic#6 - BTS) - Justin defeated Malphegor but refused to kill him like Cyttorak wanted.

Comments: Created by Emily Kim and Minkyu Jung.

    The timeline as presented is a little problematic, as if Jung-Woo was born circa World War II, and he has a son who is like 18 in the present of the modern/heroic age, he would have been like 62-years-old when Justin was born. That's certainly doable, but it makes it awkward as Hae-Ran didn't look to be over 40-years-old (although she could just look young). And Jung-Woo ages a year every year in real time. Maybe even though he didn't ever touch the Crystal of Cyttorak, its mystic energies helped keep him young.

This profile was completed 04/13/2026, but its publication was delayed as it was intended for the Appendix 25^th anniversary 's celebratory event.
Thanks to Loki for suggesting Jung-Woo Jin to represent Kid Juggernaut for the event.
