A/N: Hey guys and welcome to season two of Supernatural Anime; Now I thought I'd start this season off with an Anime that I've been waiting to use since I first got started on this story, and it's also one that a lot of people have been requesting as well.

Disclaimer: I don't own Supernatural nor do I own any of the anime that is mentioned in this story.

Castiel was setting in the motel room by himself with the Pichu siblings standing in the table pretending that they were Sam and Dean, while they were wearing some of their clothes which was WAY to big for them.

The Angel was watching a show about a young boy with blonde hair, a red jacket, and most of all he also had a metal arm and leg. He was traveling around with a walking of suit of armor, who was helping him fight off strange looking monsters.

As he stared at the TV he couldn't help but notice some similarities between the two main characters and the Winchester brothers, like how the blonde haired one can be a bit rash, impulsive, temperamental, smart-aleck, and he wants to protect the suit of armor; in a way he was just like Dean.

The suit of armor seemed the be the kinder sensitive one of the two, he seems to take other people emotions into consideration, and he's looking out for the blonde boy's wellbeing, just like how Sam acts.

Keeping his attention on the TV, Cas didn't seem to notice the sound of the Impala pulling up into the drive way, but the Pichu siblings on the other hand did as they jumped off of the table and ran towards the front door.

"You know Sam you can such a killjoy." Dean whined as he and Sam walked into the room only to be surprised to see both of Pichu siblings in their clothes standing in front of them.

The one with the spiked ear was dressed and acting like Sam and the others was dressed and acting like Dean.

"Cas what did we tell you about letting them wear our clothes?" Dean asked the angel on the sofa as he walked pass the two mouse Pokemon.

"My apologies." Cas answered while not taking his eyes off of the TV screen.

"Don't mind him guys he's just a little grumpy right now." Sam said lifting up the little Pokemons spirit.

"Chu!" they both cheered as they both climbed onto the younger Winchester's shoulders.

Cas couldn't help but stare at the Winchesters and characters on the TV, while at the same time making comparisons at both of the groups.

"Cas what are you watching and why do you keep looking at us like that?" Dean asked the angel while taking a sip of his beer.

"FullMetal Alchemist Brotherhood" He answered the older Winchester with his gaze still on the TV.

"Alchemist?" Dean asked with a confused look on his face.

"It's somebody who practices alchemy, which is an earlier and unscientific form of chemistry, seeking to transform base metals into gold and to discover a life-prolonging elixir, a universal cure for disease, and a universal solvent (alkahest)." Sam answered as he helping the Pichus get undressed.

"Thank you for the nerd lesson Sam." Dean told his little brother before turning his attention back towards the angel on the sofa. "So I take it that's what this show is about then."

"No, it is about two brothers named Edward and Alphonse Elric, and their quest to find the Philosopher's Stone so they can restore their bodies back to their original forms." Cas answered him with his gruff voice.

"What do you mean by restore their bodies back to their original forms?" Sam asked walking over to the angel.

"When they were younger their father had left them and their mother." Cas said as he began to talk about the Elrics.

"Why does that sound so familiar?" Dean asked sarcastically as he took another sip of his beer.

"Then sometime later their mother had fallen gravely ill and passed away, so after much research they conducted and experiment to bring her back to life." When Cas said that he saw the shocked look on the Winchesters faces.

"You mean to tell us that they actually tried to bring her back to life?" Dean asked knowing full well how these things turn out.

"How is that even possible? I didn't think that Alchemy would be enough to pull something like that off." Sam said with the same look on his face as Dean's.

"Their laws of Alchemy are different from the ones that you are familiar with, and the type of Alchemy that they performed was a forbidden art called Human Transmutation; in which by law of Equivalent Exchange, the initiator must give something of equal value for it to work." Castiel explained with his gruff voice.

"What do you mean by 'Law of Equivalent Exchange'? and what does the person have to give in return?" Sam asked him out of curiosity.

"In order to obtain or create something, something of equal value must be lost or destroyed. In a standard practice Equivalent Exchange is separated into two parts, The Law of Conservation of Mass and The Law of Natural Providence." Castiel explained to the two hunters.

"What did those boys have to give up? I'm pretty sure something like that would cost like an arm and a leg." Dean asked with the same curious look on his face as Sam's.

"That is correct, Edward lost his left leg and Alphonse lost his entire body in the ordeal; Edward also offered his left arm as to prevent his younger brother's soul from crossing over to the other side by soul bending his soul to a suit of armor, in order for that to work he had to draw a rune in blood, but it is only temporary because at some point the soul and the object that it inherits will repel each other the longer the two are bound." Castiel explained to the surprised Winchesters.

"So in other words they crossed over into God's turf and now they're the Tin man and Metal Midget." Dean summarized to the Angel.

"He does not like being called short." Cas stated to the older Winchester who simply shrugged it off.

The two Pichus then ran over to Cas and climbed onto both of his shoulders and pointed to both of the Winchester brothers.

"Another thing that I noticed about this show is the fact that Edward and Alphonse are just like the two of you." He said to both Sam and Dean.

Upon hearing this both of them were in a bit of shock and just stared at each other in a short silence before turning their attention back to the angel.

"Alright then Cas how are they just like us?" Dean asked him with his arms folded wanting to hear the angel's answer.

"They both have an absent father, their mother died when they were very young, they wanted to bring her back from the dead and the results were disastrous for them; they travel around and help people whenever they can, Alphonse is a kind and caring person who has to control his brother at times just like Sam, and Edward is stubborn and temperamental just like Dean." Cas explained to them.

Sam had a bit of a smirk on his face while Dean on the other hand sent his brother and the angel a little glare.

"They also battle creatures called Homunculus which are artificial humans brought into existence by the way of alchemy; they are each named after the seven deadly sins of Pride, Lust, Greed, Envy, Sloth, Gluttony, and Wrath. Greed is some what of a ally to the Elrics partially to Edward." Cas stated checking to see if the two brothers were paying attention to him.

"The most important thing about them is the fact that no matter what they go through and what challenge they may face, they always stick together and look out for each other through even the harshest of times, that is the main similarity I see between you two and the Elric brothers." Castiel explained as the two Pichus nodded their heads in agreement.

Sam and Dean couldn't help but smirk at what they just heard, the only thing they could do was nod their heads in agreement at what Cas just said. They have been through a lot of crap in the past and dealt with a crap load of angst, but just like the Elrics they had each other to count on.

"Another thing that you both have in common is that the older brother is shorter than the younger brother." Cas stated which caused Dean to glare at him.

"Hey I'm not short! Sam is just freakishly huge compared to everybody else that all!" Dean affirmed to the angel.

"WHO ARE YOU CALLING SHORT? I'M NOT SHORT I'M FUN SIZE!" Edward screamed from within the TV.

Everybody present in the room then turned their attention to Dean who was scowling at the smirking Sam, the giggling Pichus, and the emotionless Castiel.

"Bitch." Dean mumbled as he drunk the rest of his beer.

A/N: Well there you go guys Chapter 11 of Supernatural Anime. Now I would like to think DigiBleach and Fullmetal Knight for the suggestion, and to be honest I've been planning on using this Anime since I first got started on this story. I mean come on Ed and Al are just like Dean and Sam.

Maybe in a future chapter I might have the Winchesters and the Elrics team up or hangout at some point, who knows except for me that is.

I'm going to mess with you guys a bit, now I am going to bring in ANTOHER character(s) from Supernatural, now I'm not saying who he/she/they are, but they will play a part in a future chapter. It doesn't matter if they're dead, alive, or in a cage, and you only get one guess for each chapter.

Now I want you guys, in your reviews to try and guess who it is and the name of the Anime as well. Now you have to have BOTH of the correct answers, the winner will get to have a cameo in the story.

I will post the answers in chapter 14, to be fair I will give you a hint for the anime: it involves a lot of girls.

Well just read and review and I will see you guys all later.
