Where you a DBZ fan in the early 2000s when it first started airing in the U. S.? Dragonball Z was one of the most searched things on the Internet.
The fact that people knew about Kid SSJ Goten, Trunks, SSJ3, Vegito, SSJ4 etc is one of the reasons DBZ blew up in the states.
Spoilers and hype is why DBZ is still a relevant anime to this day. If your pissing and moaning about spoilers then go to your fukking safe space in reddit where the nazi mods can shield you from the world.
Grown ass man crying because someone told them santa wasn't real and spoiled Christmas.
