Sun "Agressif" Zheng is a professional Chinese Dota 2 player who is currently playing for Team VG.J.
After The International 2013, Agressif joined New Element  and later played with CDEC Gaming. He came second place at the National Electronic Sports Open 2014 and into Spring 2015 he and his team rose to international prominence through achieving second place in multiple domestic tournaments and later qualifying for The International 2015 through the wildcard stages after reaching second place in the Chinese Qualifers. In tremendous form, Agressif played a integral role in the team's journey in the tournament finishing second place overall through playing notable heroes such as Ember Spirit, Phantom Lancer and Gyrocopter. While the team's goal was to reach the main event, they exceeded expectations and Agressif was happy with the result achieved. 
After the International he finished in the top 4 at ESL One New York 2015 and MLG World Finals 2015 but saw an uneventful 2015-16 period for him. He later moved to LGD Gaming after the Shanghai Major 2016 and won two domestic titles to his name: ECL Autumn 2015 and DPL Season 1. He also finished in 4th place at the Manila Major 2016 but after an early exit at The International 2016, he later departed LGD Gaming  to join Team VG.J.
