Alright. Request two characters that you want to see fight, then I use my power of logic to decide who would win. I will add one A day. Please do not request two characters from the same series.

Goku (SSJ1) vs Superman

Superman would, sadly, win. Superman has survived an extreme amount of damage and can tow planets by himself. Goku does have somewhat of an advantage, because his Ki gives him a wider range of moves, but Superman is on a totaly different level of power. Goku would have to go beyond his limits to win.

Goku vs Sonic

Alright. I know there would be one fanboy who will say that sonic would win because Super Sonic has unlimited energy. Well, so did Android 17 and 18, and they were surpassed by Goku easily. In addition, Sonic simply has nothing nearly strong enough to damage Goku. Even if he was faster (he's not) he would run out of energy long before he could kill Goku. And with Instant Transm Goku is faster than light itself. Plus with his infinite Ki control, and therefore nearly infinite amount of moves, there is no way for sonic to defend. Goku Chichiwins

Spiderman vs Chichi

This fight is...interesting. Chichi actualy is a decent warrior. She was able to defeat one of Slug's minions. But Spiderman is far faster and has a much greater amount of skills, and considering Chichi has no ranged moves, spiderman wins

Vegeta vs. Shadow

Look at Goku vs. Sonic. Vegeta is weaker than Goku, Shadow is stronger than Sonic. Do the math

Luke Skywalker vs Yajirobe

This is rather interesting. Yajirobe is very strong fighter, perhaps stronger than Luke. But however, Yajirobe's inability to use Ki is a severe weakness, considering that Luke is much stronger from a distance. Plus, the lightsaber would probably just cut Yajirobe's sword in half, followed by the swordsman himself being cut in half. Sadly, he's just not cut out to fight such an opponenet. A winner is Luke

Broly vs The Hulk

This fight seems a little unfair. Sure the Hulk is strong, and said to be immortal, but it was a nuclear blast he survived, not a Galaxy exploding. Plus the Hulk can't do much more from a distance then throw useless rocks. Throwing a planet at Broly wouldn't hurt him. The Legendary Super Saiyan wins
