After reading the manga, will I find out who all these people are?

Vegeta just "swatted Kiwi like a fly" on planet Namek, and just revealed how he can consentrate his power to up it from 18,000 to 24,000+

vegeta rocks, and I really enjoyed te sequence where Picollo trained Gohan makes Picollo SO much cooler.

COME BACK TO LIFE PIC!!!

Aren't we talking about DBZ?

Or does D include DBZ or is he in DBZ?
