If you follow the show, you know that Goku and several other characters belong to the Saiyan race which gives them the ability to transform into Super Saiyans. In this form, Goku, his son Gohan, Goku's rival Vegeta and others become more powerful and buffed up. Consider this to be similar to taking mega-doses of steroids. The transformation into a super saiyan is a rite of passage for male saiyans. You can find Dragon Ball Z mobile games to play on both the Apple App Store and the Google Play Store.

Google adds a Dragon Ball Z Easter Egg to Google Assistant
To crack open the Easter Egg on an Android phone, activate Google Assistant by saying your hotword ("Hey, Google" or "O.K. Google") and follow that up by saying "Go Super Saiyan." Google Assistant should then play the sounds that Goku made when he transformed into a Super Saiyan for the very first time. We can assure you that the Easter Egg does work even if you're using the iOS Google Assistant app installed on an iPhone. Keep in mind that the Easter Egg runs only with Google Assistant set to run in English. If you have it set on another language, you'll need to change the setting for it to work.
If you have friends who are DBZ fans, tell them about the Easter Egg. They'll be happy that you passed it along to them.
