Xiaolin Showdown
When an universe is this small the fighters are usually just the good and bad guys of the universe. This universe has Jack Spicer and his Jack-bots, Tubimura,
Katnappe, Chameleon Bot, Omi and the rest of Chosen ones, Master Fung and the monks and finally Mala Mala Jong and the Sapphire Dragon. I consider the creatures
of the Shen-Gong-Wu as entities to be considered separate from a user unlike the other Shen-Gong-Wu, which are also something to think about in this battle.
I haven't seen all of the items yet but I think I have enough to do this battle. I would say that the rest of the Shen-Gong-Wu
would be divided amoung the Chosen ones and the bad guys. There are a few other characters that I remember but my rules say that they have to show up
for more than one episode before I use them: Le Mime, that black kid, and Jack's huge robot.
Terminator
I probably don't have to list them but I will anyway. Here are the fighters I am considering: T-101's, T-1000's, T-X's, Hunter-Killers, and the Human Rebellion.
They have a time machine but they can only go back to the beginning of this battle so unless its useful I won't let them use it.
The Fight Readers should know by now that I am too much of an engineer and that I am really systematic in how I do these battles. The monks and the human rebellion are pretty much the low end of the totem poll when it comes to power. The Human rebellion will obviously take out the monks with their pulse weapons. So again I simplify the battle down to the Chosen Ones and the Bad Guys vs. the terminators and the wild cards: Sapphire Dragon and Mala Mala Jong. The Sapphire Dragon would take out the Human Rebellion with its transmutating breath, turning the rebels into sapphire warriors at its command. The Dragon is invulnerable I am assuming. I assume it can at least take a shot from a pulse weapon since the item was found in the heart of a volcano. Mala Mala Jong is composed of some of the most powerful Shen-Gong-Wu so he is a force to be reckoned with. The fist of Tebigong can easily take out a Terminator or a Hunter/Killer in my opinion. If not, the Eye of Dashi will do the job. The Two Ton Tunic protects him from the Terminator's attacks. The Jack-Bots break easy so forget about them. The Xiaolin fighters have the rest of the Shen-Gong-Wu, which in my opinion are just useful for defensive purposes. The only really good ones that Mala Mala Jong isn't using are the Sword of the Storm, the Orb of Tornami, the Star of Hanabi and the Golden Tiger Claws. The first 3 are obvious as to how they could be useful, as they could destroy Terminators if used right. The Golden Tiger Claws could be used much in the same manner as Omi used to defeat Mala Mala Jong: teleport inside and remove a piece. I would think that Jack Spicer would think to teleport in and remove the power core. The rest of the fighters can use the other items to dodge and distract the Terminators. I am sure that they all can work together well enough for this kind of plan.
I am assuming that none of the human rebels know or can figure out how to use the Shen-Gong-Wu, and I don't think a Terminator can use the Shen-Gong-Wu either. My rules say that a win can only be claimed when all of the fighters on one side have been taken out. So as long as the Xiaolin fighters keep dodging the crossfire (using the Mantis Flip Coin and Monkey Staff), they could win. Here is the problem: Skynet is in orbit and is the brains behind of the Termintor universe. So unless my info is wrong about Skynet, the Xiaolin have to take out Skynet. I have ways for them to do this: 1) Jack creates a space capable Jack-Bot to take out Skynet. This may not work if Skynet has its own defensive capabilities. 2) The Golden Tiger Claws can teleport Jack (who I gave the Claws to earlier) to the satellite to take it out just like the Terminators. 3) Mala Mala Jong has the Jet Bootsu, allowing him to fly. Nothing says he can't fly into space to take out Skynet.
I never mentioned any of the abilities of any of the Terminator models, mainly because they are assumed to be well known. In addition, I believe they are irrelevant. I always find the one thing that makes the win for the winner. In previous battles it was the Borg or the Replikators. Here it is Mala Mala Jong and the Sapphire Dragon (which I allow here despite only appearing in one episode on the basis that they are Shen-Gong-Wu, the main focus fo this show). These 2 will clean up and are unstoppable, the rest of the Xiaolin are just taking up space.
Update: I saw the Sapphire dragon episode for a 2nd or 3rd time today and I realized something. In the scene where Clay is turned into a sapphire statue, we see Dojo scratch the dragon with his claws. Dojo is not that strong and his claws can't be that sharp. So my assumption of the Dragon's invulnerability was pretty stupid. Although I will stick with the bit about it surviving the heat of a volcano and therefore can withstand a pulse blast. The Dragon is still important to this fight. His control over the humans he does manage to transmute makes a big difference. In the end this doesn't change the battle, Mala Mala Jong still kicks ass.
