The Warrior King

The warrior king, an all mighty being from another world, ends up on Earth, hunting down a powerful orb which grants the user great power. However, when Bison gets his hands on it, it's up to the warrior king and Chun-Li to stop him from taking over the world.

The start of this episode has several dragons attacking the warrior king's castle. Inside the castle, the warrior king's helper (he never gets named, and only appears in this scene) tells him that they cannot risk losing the orb to the enemy force and that the orb should be sent away, under the protection of the warrior king. He opens up a portal, even though the warrior king prefers to stay and fight.
 

However, the enemy breaks into the castle and a lucky shot hits the warrior king, sending the orb into the portal. The warrior king is ordered to follow it, and he jumps through the portal. The orb, meanwhile, lands on Earth in a barren patch of land. As soon as it lands though it starts to make new plant life on the land, and several peasants spot it. They decide to take the orb to their prince as they think he will know what to do with it.

Unfortunately, Bison and Sagat find out about the orb through a great power surge. They set out to go and claim it for themselves. Meanwhile, Chun-Li reports how the barren land has now become a beautiful garden in a ridiculously short amount of time. The prince appears to give a speech on how it was done, but instead the prince says that Bison now has the orb. Bison starts preaching that he only intends to use the orb for good, and gives a little demonstration by giving some more of the dead land a make over.
 

Bison says that all the other nations will be able to benefit from this power, but they have to pay for it. Inside the palace, Bison regroups with Sagat and Zangief, saying that the prince is having a party tonight in Bison's honour. He hopes Chun-Li will go there, so they can dispose of her. At an SF HQ, Escher tells Chun-Li to go to the party, and also tells Guile to get a team ready to move out just in case Bison suddenly starts using his new power for evil.

Back out in the now transformed lands, the warrior king arrives. He talks to the peasants nearby who tell him that they took the orb to the castle where the prince is, so the warrior king sets off to there. The party begins, and Chun-Li finds Bison, but Zangief grabs her from behind whilst Bison starts to charge up the orb.

The warrior king turns up though and starts to threaten Bison with his...shiny stick. Bison, being the moron he is, tries to blast him, but ends up destroying most of the balcony, sending Zangief, Chun-Li and Sagat into the water below. Bison falls and drops the orb, so the warrior king leaps over and tries to grab it, but before he can get it Bison blasts him with a laser. The orb falls into the water.

Sagat manages to find the orb... and a fish... and then uses the orb to call up vines, which wrap around Chun-Li and tie her up. A news crew films this, which Escher and Guile watch. Escher tells Guile to move his team (consisting of himself, Ken and Ryu) out to stop Bison.
 

Back at the fight, the warrior king uses his stick to cut open the vines and free Chun-Li. Sagat uses the orb to try and trap them, but fails miserably. Bison reclaims the orb from Sagat and watches as Chun-Li and the warrior king get out of the water, he says he'll stop them but they manage to get away. In a forest, the warrior king and Chun-Li exchange stories, and decide to work together to stop Bison.
 

Bison says that if the A.N. doesn't give in he'll take over the world, and shows Escher several counties facing destruction thanks to the power of the orb. The team lead by Guile nears where Bison is, but Bison has put a huge tornado all around his base, and the plane starts to break up in the air. Guile, Ryu and Ken eject just as the plane crash lands and explodes.
 

Chun-Li and the warrior king fight a bunch of Shadowloo terrorists, just to get Chun-Li's proper costume back. In one shot, Chun-Li is actually drawn well here, and almost looks like she does in the SF2 anime, for some reason. In the A.N. head building, Escher tells all the world leaders not to give into Bison's threats, and that he has sent out several agents to deal with him. Guile and his team are outside Bison's base, but giant walls stop them from getting inside. They try to break down the wall by throwing Hadokens and Sonic Booms at it, but they barely do any damage to it.
 

Bison now gives the A.N. an hour to give in and surrender, and bring him a treaty which makes him world leader. This happens just as Guile, Ryu and Ken manage to break through the wall, but Guile then learns that they are too late. However, the warrior king and Chun-Li start their attack, and the warrior king blasts the orb from Bison's hands.
 

Chun-Li starts to fight Bison whilst the warrior king takes on Zangief. Sagat spots that the A.N. have arrived, but instead of coming bearing a treaty for Bison, they're actually in war planes. The warrior king managed to grab the orb, and sees that a portal has opened up nearby. Before he can go through it though, Bison hits him and he drops the orb.
 

The orb ends up going through the portal (much to the disgust of Bison, judging from his hilarious expression), and so the warrior king has to make a choice between going through the portal himself staying to help Chun-Li. Chun-Li tells him to go through as his people will need him back where he comes from. The warrior king leaps through the portal just before it closes.
 

And it's at this point where the A.N. do their clever plan: fire lots of missiles to blow this shit out of Bison's little hideout, not bothering to think of Chun-Li's safety. However, they luckily manage to send Bison, Zangief and Sagat flying, and the three are forced to retreat.
 

With the bad guys defeated, Guile, Ryu and Ken show up and tell how Chun-Li did well to hold up against Bison for so long. Ken then asks if Chun-Li needs a boyfriend for next to no reason at all, only for her to tell Ken that she already as one and hopes to meet him again someday.

The warrior king character seems to be based loosely... and I mean very loosely... on the main character of the Capcom arcade game Magic Sword which was released in 1990. The game's storyline revolves around a barbarian fighting through a tower to destroy a black orb of incredible power. However, the game's ending gives you two choices, you can either pick the orb to control it (and fail miserably) or destroy it, see this page of the VG Museum.

This claim can be backed up at the start of the episode, the attackers use staffs to shoot laser blasts at the warrior king's castle, and the staffs look pretty much like the ones seen in the Magic Sword game:

Of all the crossovers they could have done though... they chose Magic Sword? It's a very little heard of game. Then again, this is one of the better episodes of the Street Fighter cartoon, but I can't help but imagine it would have been if they did a few more crossovers, like maybe throw in Strider Hiryu or Captain Commando.
