The main character for all three series (for the most part) of dragon ball Goku is a character that always finds a way to surprise us. In the Dragon Ball series he is just a young kid with a tail that some refer to as "Monkey Boy". He shows an extreme talent for martial arts and puts his opponents to shame either in random battles or in tournaments. He always shows extreme kindness and love for everything around him, even for those who would rather beat him up or give him a hug. Thanks to training by his Grandfather, Gohan, he was able to do many things at a young age. However we find in the Dragon Ball series that being raised out in the woods with only his Grandfather would neglect him certain common knowledge about life. In the dragon ball series we get to see him learn alot of new things about himself and the world. As he gets older he gets stronger but his heart always stays the same. He learns that he is an alien to planet earth and comes from a planet called "Vegeta". On top of this when he had his tail seeing the moon would turn him into a huge ape like monster. Through out the series Goku fights to protect earth and even the universe. He learns new skills and tactics and always does what he can to help evil people learn the wrong to their ways, even if it could cost him his life. By the end of Dragon Ball Grand Tour Goku goes all the way up to Super Saiyan Jin 4, has two kids(Goten and Gohan), and Saves the world against a number of enemies. His corkiness and crazy mantallity along with his extreme talent in the fighting arena make Goku a character that people have enjoyed for years. .
