My top 8 Dragon Ball and Sonic the Hedgehog similarities

So with past entries I've made countdowns discussing the similarities between two different sources of entertainment. And so, now, I've decided to talk about a pretty obvious one from Japan, Dragon Ball and Sonic the Hedgehog. My brother and I have both made jokes before about the different similarities between these two. There's so many that anyone can make. In fact, you could really say that without Dragon Ball, Sonic never would have existed. And, yeah, 8 was all I could think of, that's why I made this 8. And so, let's begin and I hope you all enjoy this.
8. Bulma, Tails:

Starting us off are the two main hero geniuses of the group. Bulma and Tails are both engineers who create tons of inventions for the other heroes. They both also started their engineering careers at a young age with a plane being their main vehicle of transportation. They're also some of the closet friends to the main hero, with Tails actually already being Sonic's best friend.
7. Androids, Metal Sonic:

These two robotic devices were all created to kill the main hero. Dr. Gero created the androids as a way to kill Goku, as well as creating Cell. When Dr. Eggman first saw Sonic in action, he thought the best way to beat him would be to create an evil robot version of him. Also, the fact that both the androids and Metal Sonic eventually turned on their creators and they're some of the hardest opponents the heroes have ever faced.
6. Dr. Gero, Dr. Eggman:

Speaking of which, both of these mad scientists are at number 6. When Goku returned to Earth after Namek, he found out some androids were out to kill him. And Dr. Gero was the one who created them. And Sonic's archenemy is Dr. Eggman who sorta has the same goal to kill the main hero. Both are machine creating evil doctors who want nothing more than to kill Goku and Sonic and then take over the world. They also, like I said, are eventually betrayed by their creations.
5. Trunks, Silver:


These two time travelers are both from a devastating future. With Trunks, he comes from a future destroyed by the androids while Silver comes from one destroyed by Iblis. Both of them then time travel to the past to destroy a target that they believe will put their time back to normal. They both also have silver aspects to them. I know Trunks' hair is purple, but in Dragon Ball Z, it looked silver and Silver's name is literally Silver.
4. Goku, Sonic:

At number 4 at the main protagonists of these two franchises. These two are both extreme optimists who always fight for their friends no matter what. Also the fact that they're both incredibly fun, fast and have a lot of the same personalities in even more ways. And the two of them just show off who they are in such similar ways and they both always try to save they're friends and even try to become better than they are.
3. Vegeta, Shadow:

Probably the most obvious one of them all, both Vegeta and Shadow are practically the exact same. In fact, there's almost no difference between the two. They're both pretty much anti-heroes and they both look the same, act the same, sound the same. There's practically no difference to be found with them. But that's not entirely a problem. They're both great characters and it's fun to watch them both.
2. Super Saiyan, Super Sonic:

My brother and I like to make biggest joke with these two by saying Super Sonic is the number 1 biggest similarity to Dragon Ball. Personally, I think there's one more, but still, yeah, Super Sonic is the exact same as Super Saiyan. The character going gold in some way and getting stronger. But, actually, there's something I actually discovered by myself kinda recently. When Sonic and Goku are in their normal forms, their hair and spikes are just fine. And when Vegeta and Shadow are in their normal forms, their hair and spikes are always up. And when they go Super, their hair and spikes stay the same, but when Goku and Sonic go Super, their hair and spikes go up, exactly like Shadow and Vegeta. That's another similarity between the two.
And the number 1 Dragon Ball and Sonic the Hedgehog similarity is... Seven Dragon Balls, Seven Chaos Emeralds:

And finally at number 1 is the main thing to do with Dragon Ball and the objective of the Sonic franchise, the seven Dragon Balls and the Seven Chaos Emeralds. Considering the whole series of Dragon Ball is named after the Dragon Balls, it would kinda be silly to ignore this fact, but while both the Dragon Balls and the Chaos Emeralds have different powers, there's the same amount with the two of them and the heroes are always searching for them. They're also the target for some of the villains too. They also help defeat the villains in a couple of occasions. And so everyone, those are my top 8 Dragon Ball and Sonic the Hedgehog similarities. Thank you all for reading and please comment to tell me what you think, and if you think I missed one, please tell me what other similarities there between these two.
