Shenlong(Spirit Dragon or Dragon of Spirit) Kami Version
150
神龍, Shenlong ("Spirit Dragon" or "Dragon of Spirit")
is a magical dragon who can be summoned by collecting all seven of the mystical artifacts known as Dragon Balls. He was created by the Kami the gurdian of Earth but he was easily killed by the demon king piccolo with no effort who in the official Daizenshuu 7 book was labeled as having a power level of 500.The way i came to this conclusion was when i took the power level of Tambourine (340) and made it a percentage or king piccolo's power level (500). it was 70 percent so i took 70 percent of Kami's power level (220) and that was was 150.
