Pre-Debut
Thunder was born in Busan, South Korea but grew up in the Philippines, where his eldest sister, Sandara Park, achieved nationwide fame in 2004 after winning 2nd place in a talent search reality competition. He first appeared on national television when he attended the finale with his mother.
Later on, as his sister began her hectic activities as a celebrity, a crew from one of South Korea's biggest TV agencies recorded her daily life in the documentary, "My Name Is Sandara Park." This marks Thunder's first ever appearance on Korean TV.

 Sandara's eventual decision to pursue activities in their home country led to their family's return to Korea in 2007. By this time, Thunder had finished secondary education in the Philippines. It was later on revealed in a magazine interview that he had originally decided to pursue a professional career as a soccer player, specifically as a midfielder. He gave up and instead started auditioning for entertainment agencies, one of which was JYP Entertainment.

 He had taken dancing workshops offered by Sandara's home network back in the Philippines. Thunder eventually became a trainee under LOEN Entertainment, where he met singer IU. He appeared in IU's debut MV for her song "Mia" and was also seen in a couple of self videos with her wherein they sing Big Bang's "Lies" and Super Junior's "Sorry Sorry."

2009 debut under MBLAQ
After training under Rain and J.Tune Entertainment, Thunder became a member of South Korean quintet male group MBLAQ, serving as a vocalist, lead rapper, lead dancer and also considered as MBLAQ's visual. The group debuted on October 9, 2009 at Rain's Legend of Rainism concert where they performed various songs from their then-unreleased single album Just BLAQ. Their performance was met with praise, with many concert spectators and fans considering them to be the next TVXQ.
