LSSJ_Malick_for_Kaiju_Z_by_DragonballXE.jpga, the executionist.
Kencha is one of the surviving saiyans of Planet Vegeta's explosion. He was on a mission during the genocide, away from his squad. Before the explosion, he was teamed with a young saiyan named Arcarus, Scarface, and Onio. Kencha took a leadership role in the team, and was nicknamed The Executionist, because he killed more native life forms then most saiyan elites.

Attack on Earth
Kencha felt a high energy on Earth one day, that reminded him of Arcarus' power. Arcarus (now going by Shane), who was adopted by Gohan and Videl, was in fact on Earth. Kencha arrived, and made his presence felt. He took out Videl, kidnapped Gohan and Videl newest son, Son Ryder, attempted to kill Ryder, and assaulted Mijime, Shane's friend. He then battled Future Gohan, Android 16, Shane, then an enraged Present Gohan.

Aftermath of the attack
Kencha then saw the error of his ways and took peaceful residence on Earth, befriending Mijime, Kevin, Gohan, and Shane. He and Shane still fight a lot, but that's expected.

(Pre-Attack) Time Paradox Incident and Invasion Of The Serpent Planet
When Kencha was 20, he went on a mission. On this mission, the time paradox altered while Kencha was in it, sending Kencha to an 8-Year-Old body. This mission was the invasion of the serpent planet. He fought a young demon named Draco there, who was also 8. The fight ended with ultimate defeat, but Kencha was stuck as an 8 Year Old.
