What has a guy named Boyakki (fans of Time Bokan series certainly know him) got to do with Dragon Ball? Now we're going to explain...
A friend of our forum hides himself behind this nickname and enjoyed collecting some curiosities about Dragon Ball's world! Give a look and will discover some very interesting things!! ^__^

We can also find some unexpected references to Dragon Ball world in the videogames!
Even Capcom, the famous Japanese Software House, has been "contaminated"! However ^__- we don't talk about one of its perfect arcade, but of the platform "Mega Twins", a less popular title, far from its best.
Look at these pictures...

Here is a short sequence, where the character jumps on a cloud (luckily it is white... cause if it was jellow, I would find fault with it! ^__^) and goes on the top of a very high building...
... which is just like Karin-Sama Sanctuary!
And take a look at its occupying!!! He introduces himself as God Meius, and he's not a cat but a goat! And the vases in the background?! What do you think of them? I think I saw them already somewhere... and the same for the stick which emerges from one of them.
But that's not all folks... Look at these pictures that show the ending of the game: there are (also here) some spheres to be gathered (and do note that they are called "Dragon Eyes"!) to summon a dragon which appears climbing up the sky!!!

There is not need to say something about the following images... They show one of the possible endings of the game "GunBird", from Psikyo, another Japanese Software House. Do read and, above all... look which is the Chinese graduate Yuan Nang wish!! ^__-

What do you think about it? Isn't she better than Goku? ^__-

And now take a look at these screenshots... This is a very popular video game that you surely saw somewhere... That's Metal Slug a series of action-shooter platform.

One of the secondary targets of the game is to set prisoners free that you meet during the mission.
Usually the bonus are special items (arms, points, etc...) but some of those follow your character and to help you they shoot... Kamehameha!
These images show the sequence: charging, shooting and hitting the target.

And here is Sonic the Hedgehog, the flagship character and mascot for the video and arcade game company Sega coming in this section: he looks like Saiyans from Dragon Ball when he becomes Super Sonic! Take a look at these animated GIFs we made for you! Click on the previews... ^_-
