Young Phineas' POV:

I am a six years old boy, my step-daddy drove was to the Animal Shelter to pick out a new pet a year after Bucky got sick and went to live on Kindly Old Man Simmons farm, we enter the shelter, Dad said "Come on, kids. Pick out any pet you want."

And my Candace sister yelling "Why won't anything look at me!"

Ferb and I walked to a baby Platypus, "Ferb!" I say to my brother "This one's looking at both of us at the same time!" the little Platypus chittered, and mommy goes "Awww." and Candace "That thing? You're kidding right." A lady who works here came to us and asked 'Is there I can do for you?" Daddy answered "Ah, yes, we'd like one, please." the lady seemed surprised and asked "You want to adopt a Platypus?" and daddy replied "Oh, is that what it is? Well, yes!" he turned to her and continued "May we have him please?" and Candace asked 'What would you even name a Platypus?" and Ferb and I said at the same time "Bartholomew."

And Mommy and Daddy paid for the Platypus and when we got home, we renamed him 'Perry."

-Meanwhile in the eastern alps of Japan-

Hawk's POV:

I am a 6 month old Gerbersian Wolfhound, and I live with my sister Sheila and my mother Keiko who's a Rhodesian Wolfhound, my grandfather on my mother side was a Rhodesian Ridgeback, and my grandmother was a Irish wolfhound. My father was also a Gerberian Shepsky, my grandfather on his side was a German Shepherd and my grandmother was a Siberian Husky, and my great-great-Grandfather was John's, he found a mate weeks before meeting Hook, it's too bad that my Great-Grandfather never meet his father.

We live in the Eastern Alps several miles off from Futago pass, which leads to Gajou the Dog Paradise where we heard that the Ohu lived, we heard stories of them, and I wonder what it'll be like being a part of them.

Sheila and I were playing then all a sudden our mother pushes us behind a rock in the cave we live in "Be still and quite. I smell something." My sister and I peered around the rock as we saw our mother walking to the entrance where there is a young tiger standing, growling at mom, the tiger is looking hungry.

The tiger run at our mother she jumps back then she bites the tiger who then return with a slash to her left side leaving a bleeding gash. She let go and the tiger pounced on her and bit her right shoulder leaving a wound, she kicked him off her. Then the tiger run at her and bite the back of her neck, but she ran and slammed him into the wall, the tiger let go of her, the tiger fell to the ground and pulled himself back on his feet and slashed at her face, mother had three gashes on her face, I can't take this anymore, so I decided to ran to defend mother, the tiger turned around pick me up and toss me back, I hit the rock, then I saw mother lunged at the tiger, then I lost conscienceless as I close my eyes.

Nyoko's POV:

I am a Irish Wolfhound German shepherd mix, and I was walking with my brothers Galahad, and Hacker, "What is the commotion?" asked Galahad we looked towards a dark cave, and then we saw a tiger fighting Keiko we are friends of hers, "We have to help her!" barked Hacker, we ran to the cave, the tiger had Keiko by the neck, "Drop her tiger!" I commanded "And get the heck out of here!" then tiger toss Keiko to the side right into the wall, "Who the freak are you to tell me to do!" "I'm Nyoko, these are my brothers Galahad and Hacker, and we are from the Ohu." I barked at the tiger who responded "You got no jurisdiction over here!" he came running after us, I step aside bite him the back of his neck, "I can take on all three of you at ones!" roared the tiger and Galahad barked "Careful who you pick with, especially how many." then Hacker added "Yes, because may lose."

The tiger roared "I don't care, I challenge you lot all at once." I replied "Fine you've asked for it." We pinned him down Hacker bite him in the back and Galahad bite him in the lag, then I toss him out of the cave, he came back running at us again, and I bite him in the throat and toss him aside, Galahad bite him, picked him up and toss him away again, the tiger then get up now looking afraid, we step forward and he flinch "Now you think twice before you decided to challenge more foes than you can handle, now get out!" he turn tail and high tailed.

"Mother!" the pups mourned, I turned around and saw her laying still, her eyes were blank and lifeless, I turn to her young pups, then to her son, I saw a minor bruised on his head, "Mother?" he whimpered "NO!" I then told the younglings "Hawk, Sheila, we were friends to your mother." the mournful Pups looked at me, Sheila put her head on me, I thought "Kyoko." Sheila whimpered "I miss our mother!" Hawk had his head down, I replied "I know.", and then I informed them, "Your Father, was one of the top three, the right-hand dog to the leader of Ohu, and so was your great-great-grandfather." Then I turned Keiko's body "Galahad, Hacker, and I will take care of your pups" I felt as much lost as the young pups mourning for their mother, she was like a sister to me, and she was a great friend. After we buried Keiko, we head our way west to Gajou.

-2 weeks later-

Sheila's POV:

After two weeks of journey, we almost to Gajou, we near a backyard with humans talking in Japanese and English couple of miles off from the border of Futago Pass just enough that it will not valuate binderies. The humans we saw are around the backyard fire pit, our Mother told us be careful around humans, "Don't worry about those humans they're harmless." Hawk and I turn to Galahad who was barking, "They're just an animal-loving family with their relatives' visiting them." and they speck both Japanese and English." Hawk replied, "I never see one or heard one before."

I looked to them there is something about them I like, Nyoko barked "So, are you guys hungry?" we nodded, Hacker barked "Okay, then check this out." , then walked out in front of them, and sat down "Look a dog!" I heard a little brown hair Japanese-American boy with green eyes in blue long pants, and a blue shirt with two stripes around the torso exclaimed. Hacker tilted his head to the right, with his ears down whimpering, "Oh-h-h, here you go." a woman with brown long flat hair, green shirt, and brown pants, and shoes toss him a food, he grappled it and walked back to us. Nyoko the barked "That's why his name is 'Hacker' the name means 'he'll charms his way thougth your defences'." I replied, "I like to try that." I walking out, I sat up and barked, then lay down and roll over, sat up again did a playful stance, barked again "How she's a natural." I heard my brother remarked, "Oh how cute." the women said, "Puppy!" said the boy.

After while we received a piece of food each "Okay let's continue." Nyoko barked, I replied "Wait a minute." They looked at me "I'm quite fond with them." I looked at the boy "Specifically that boy." Hawk then asked "So what do you mean?" he's a bit surprised, so were the other two dogs except Galahad, he look like he understands "I see what you going here." he barked "Are you sure this what you want?" I nodded "Well if this is what you want then go for It." my brother Hawk barked, I replied "Thanks."

Hawk's POV:

I saw my sister gone to the tourist visiting their relatives, "I'll miss you." I barked, "I'll miss you too, love you." Then she turn to walk to the family, "Mommy?" said the boy "Yes, Thomas." said the boy's mother "Can I keep her?" asked Thomas "Well I don't know." Thomas' mother replied, "Oh, come on, Jill." A man with brown thick hair and wearing a brown suit, who is Thomas' father saying, "I think she'll be a good addition to the family." I think the boy's mother is American and his father his Japanese, Jill said "Okay, James, Thomas, we'll adopt her." then she put het finger up "But first we have to give her shots before we gone home, back in America." Then one of their relative asked "Nani desu Ni iku Namae Ni Anata no atarashii Inu?" that translates as 'What are you going to name your new dog?' "Bali?" Thomas puzzled, then suggest "Bonny?" then Thomas snapped his finger "I know!" he exclaimed "How about 'Sheila'?" I wow, he doesn't know her name is actually 'Sheila', she barked happily, licked the boy, "Okay, Sheila." giggled Thomas, James said "She acts like that always been her name." 'That because it is' I thought.

"Okay, lets go to Gajou." Nyoko bark, it is pretty stright forward to Gajou from here, then we met the Ohu and we introduced ourselves, well they know Kyoko, Galahad, and Hacker, they told them all of what happened, from the tiger attack and meeting this nice family of humans, and Sheila by her own choose gone with them, and our arrival at Gajou. They welcomed me, and one of the dogs told me "Your father was a good right hand dog to Orion, the 4th Generation Ohu leader." They let me to be part of Ohu.

-Over the seas on the American-Jap airlines

Sheila's POV:

After they gave me the required shots, the family said good-bye to their relatives, we made our way to the Japanese Airport, and Thomas convinced the family to take me on the carry-on so Thomas can hold me. Hours later, on the plane, we almost to what they called a 'Airport,' specifically 'Tri-State-Area Airport'. Thomas hold he next to the window I could see a city, we were about to land. I saw a light house, a large mall, and tall building, a woman in a blue uniform came up to us "Yoi, Anata motte iru E oku anata no inu Ni za Kyaria." This translated as 'Okay, you have to put your dog into the carrier.' Jill replied "Yoi." Thomas protested "But mommy!" Jill then said "It's the rules." then Thomas sighed in defeat, and place me into the cage under the seat in front of him.

Then ones we made it out, Thomas opened the cage and James then said "Okay it is good to be back home." Jill then said "We have to get her another series of treatments at Danville Veterinarian." Then we made our way to the Veterinarian and got me other treatments, then we made to the family's home.

-Lake Nose America-
-2 months later-

Then two weeks later, the family went to the lake called 'Lake Nose' what a weird named for a lake, and Thomas is swimming out in site of us, but then he started to frantic he was drowning, on instinct I started to swim for him, I was not about to lose another love one, he grappled me and made our way to back to shore, then they pull Thomas back on his feet, and put a towel around him, "You saved Thomas." Jill exclaimed and Thomas hugged me "Thanks, girl." A little girl who's in an orange uniform, with a cap, and sash that's full of patches, then she took a picture of me "I just got my Lil' 'Photograph a Hero Dog photo' patch." exclaimed the girl.

There was where I ment weird-looking Duck-beaver Hybrid and a Chauahah, and weird creature chittered "You saved your Owner, I'm sure you'll make a good Secret Agent." I replied, and the Chauahah barked "Yeah, yeah you will." I replied "I just did have to do, because I love my family." Then I turn to hybrid "What are you?" I asked "What do you mean Secret Agent?" the odd creature answered "I'm a Platypus named Perry, and I'm a Secret Agent working for O.W.C.A. aka Organization Without a Cool Acronym, it's an agency of animals assigned to stop evil scientists from taking over." "Well that does sound interesting." I replied "But, I take that under a consideration."

Then we went home that night there was a knock on the door, I gone through the little door and standing there was a man with a unibrow with black hair, and in a green suit with the English letters 'MM', "Hello, there, I heard about your heroic act of saving your owner." the man began "How would you like to be a secret agent, protecting your family from evil scientist?" I thought for a moment then nodded, "Good, around 900 hours you'll go through training as a Secret Agent." They taught me something I thought was impossible: standing, walking, and running on hind legs, and how to use gadgets, they told me that I shouldn't let my Host-Family know about this or I'll be relocated. Boy, I could see the amazment on my relatives and my brother Hawk's face seeing what I could do. After two weeks of facility training, I went though field training for one year.

After 2 weeks of training in the facility, I went to field training as an apprentice for an highly trained Agent.

-Japan-
-1 year later-

It took one year to complete. So I'm ready to be assign to my own Nemesis. 2 weeks after Perry was assigned to his Nemesis Dr. Heinz Doofenshmirtz, I was assigned to my Nemesis Dr. Bloodpudding, and from there, I am in-charged to stop every plan he'll think up.

My Host-Family gone back to japan for their annual family reunion, Nyoko, Galahad, Hacker, and my brother Hawk was in the forest near the relatives' backyard, apparently they know that the family visits their relatives every year, so I ran up to them and greeted them "Hey, everyone." Then I noticed there was three other "Hey, Sheila, you've grown, how is that family treating you?" I answered "They're great." We made our way to Gajou, and they introduced me to Orion the leader of Ohu, "So you're Sheila, I'm Orion nice to meet you." We talked and they show me around and they introduced me to Weed an old Akita one of the Elders in Ohu, I see some of his scars and he seen his days of battle. They introduced me to Jen they said that he is the son of Ken, and Yamaitora or Yama they also say son of Kurotora.

I decided to tell them that I'm a Sceret Agent, at least I could tell my dog family. It's to bad that I can't tell my Host-Family, "Hey guys can I tell you something?" Orion replied "Sure you can, you're just as welcome to speak here as everybody else, even if you won't stay here, you are welcome to come and go as you please." I then barked "Well I work for a Secret Agency." then an old Akita barked excitedly "So you said that you work for an Agency?" Weed asked "Just like Jorome, right?" I nodded, even at his old age he is energetic like I been told he is. "But with different types of training techniques." then Hawk asked "What type of trainnig?" "They've train us as Secret Agent, after a year of training in the field our Superiors assign us to our Nemesis who we must stop them from taking over, and informed us that we must keep it secret, I am just finish my year of training and soon I'll be assigned with my own Nemesis."

"Well, it's not a secret anymore now that you tell us, is it Sheila?" Jen barked teasingly, I replied "Well it is only kept secret from the Owners of the Agents." Yamatora replied "Why, why do you have to leave your family... well your Host-family out of the secret?" Hawk look at Yama as he continues "They're your family just as Daisuke is sort-of to us, every once awhile, some of us go to the river where it's just off the bandery of Gajou, where we meet Daisuke, he even gave Orion fish as when he was a pup." then Yama asked "Do you think they should know about what you do?" Hawk barked at him "Yamatora, she must abide to rules set by her Superiors, just as we too must abide to our leaders." I look at my brother, stated "Hawk it's fine, I have the same feeling about that rule." Orion added "Well I think it's for the protection of their family, too much knowledge could actually put them in harm's way." I thought for a moment and sat down "Yeah, yeah that's sound like a good reason." I see why he's the leader of Ohu, from what I've heard from, he grown wise, and my brother will be a good right hand dog to to the next Leader.

And after a while, it's time for me to head back to my Host-Family we said our goodbye, "Until the next Sheila." my brother Hawk called, I replied "I'll be seeing again for the next two weeks. I returned with my Owner's and Thomas said apparently most Agents' owners especially our favorites "Oh there you are Sheila." everyday for two weeks I visit with my relatives, then after those two weeks, my Host-Family once we say good-byes we returned to America.

-2 year later-

It's going the same everyday, My retain with Dr. Bloodpudding is the same as my good friend Perry, and my crush Pinky, Dr. Bloodpudding has a scheme, I come to stop him, I get trapped, he dose a cliché monologue, I escape then we fight and Dr. Bloodpudding is defeated, then return home to Thomas. But annually, I have two weeks off which I'm grateful so I can go with my family to go to a family reunion in Japan, while my Host-Family visits with their family I visit Ohu, mine dog family in Gajou.

When I arrive in Gajou, they greeted me "Hey, Sheila." Hacker barked, Nyoko greeted me with his welcoming eyes "It's always good to see you." Hawk my brother came up, and greeted me "Hey, Sheila." I greeted back "Hey, bro."

Then an old white Kishu came up to me and barked "So you're Sheila?" I looked at him, he has a look of honor "I'm Kyoushiro, please to meet you." the Kishu named Kyoushiro continue to barked "I've heard of you duty as a Secret Agent." I replied "it's good to meet you Kyoushiro." I greeted back "I heard stories of you helping weed." he nodded and then he asked "So do you really have special training?" I stood up on my hind legs, he looked up "Wow." he was in awed "That is a real good training." he his normal expression returns.

"Oh, don't show of Sheila." barked Jen, I got back on all four, smiling. Then Orion came up "Hey, Sheila, how is it at the Agency?" "It's going fine." I answered Orion, "Well, yesterday, before coming here, Dr. Bloodpudding tried to mind control every bear in the world, but I stopped him, thanks for the cliché feature that every Evil Scientist install into their machines." They gasped in surprise and one dog barked "Every bear in the world, no wonder the bears started up again then just stopped out of nowhere." Then Kyani barked "Well, that was a problem your Nemesis caused for us, luckily no one was killed yesterday." then orion added "Well, then I guess he don't need to refight the bears, then." I then whimpered "Sorry, the Bloodpudding caused problems for you guys." Weed then assured me "Don't worry Sheila no one was killed."

Then Orion barked "Well, while you were back in America, my mate Hiroko and I got a new pup, want to meet him." They introduced me to Echo the next in line, I look at the six mouth pup, being gave a lick bath by Hiroko, "Who's that mom?" Hiroko answered, paused from licking him, and answered her son "That's Sheila the Secret Agent form OWCA." he looked curious and asked "OWCA?" I smiled and answered, "Organization Without a Cool Acronym." then Echo replied "Wow, that is really uncool Acronym." everyone had a little laugh. Hours passed and then I returned to my Host-Family.

I've gone back and forth for two weeks, then my host-Family and I returns to Danville South Dakota, then my retain with Dr. Bloodpudding will began again.

-2 years later-

Dr. Heisuke Locogisu's POV:

It's been a week since the invasion from the second Dimension, and after learning about Platyborg, I remember when I was second in command to the head Scientist, who then become the manager making me the head scientist after P4 went out of control, after four years and six months I was fired, I thought what if P4 was a cyborg like that Platyborg, then it may have turn out different, then I decided to conduct an Experiment on Kaijū the Gerberian Shepsky after the manner of both Platyborg and my first Exeriment: Kaibutsu thinking it will help Agents fight their Nemesis, I firgured, to prevent the same incident I have to erase their recallations, I've tried to get the authorization for this Opperation, but the major four Superiors: Major Monogram, Admiral Wanda, Command Sargent Major Weaver, and Captain Zaker he's in-charged of the Seattle Division because they rejected my proposal of the experiment, I had to forged their authorization signature, then I restraint Kaijū to a operation table, and got him ready The reason I've chosen him because his name is an alternate word for "Monster."

Agent S aka Sheila's POV:

I saw Dr. Locogisu restraining Kaijū to a operation and saying "Alright, Kaijū, We are going to do experimentation on you." I thought that his experiment proposal was denied, this isn't right of him. I informed the Superiors immediately about this scheme, fortunately we arrived just in time, before they started, before a same type of incident with a Monster Dog named Kaibutsu that occurred at his earlier career as a scientist for a Japanese Secret Laboratory occurs here. I've been told by my Dog relatives what damages Kaibutsu caused in Japan all those years ago, I shutter that thought, the thought of Kaijū killing people and Agents.

"DR. HEISUKE LOCOGISU, WHAT IN THE HECK ARE YOU DOING TO MY AGENT?" demanded Weaver "STOP THIS RIGHT NOW!", Weaver freed Kaijū, one of the other OWCA Scientist asked "But didn't you authorized this?" Wanda replied as polite as she usually does "We did not, Dr. Gopper." Monogram stared at Dr. Locogisu crossing his arms "Dr. Locogisu, you've forged the signatures, didn't you?" Monogram said sternly, Dr. L. said nothing "Didn't you?" Monogram now demanding "Yes." Dr. L. said under his breath, "I can't hear you." said MM, "Yes." Locogisu responded "Yes, I did, I wanted to show the power as like my first experiment: Kaibutsu, with the modification as like Platyborg, so it'll be under control, and finally" Monogram cut him off "You're fired, now get out of the Agency." Zaker turn told me and said "Thankfully you informed us about this, Agent S."

When Dr. Locogisu got fired he look at me, with a look of shook, anger and hatred, "Sheila!" he retorted bitterly "Curse you!" then he yelled "You will pay for this, so will your family!" I widen my eyes give him the same look he gave me with a growl, the superiors look at him in shock as well, "And not only your Host-family." he gritted though is teeth, "Also your Dog family back in Japan as well." I widen my eyes even more, then narrow them "Wow dare you threaten my family!" I barked angrily, Perry grabbed my tail just when I lunged towards Dr. Locogisu, I wanted so baddly to rip Locogisu apart, "Perry, let go!" I barked then Brian the Bulldog and Elisa the Eagle grabbing Locogisu, but he shoved them off, he turned around and stormed out. "Okay," Weaver speak up "We should keep an eye on him." Monogram then sated "We might have an really Evil Scientist on our hands, soon."

Perry then reassure me "Don't worry Sheila, we won't le-." I cut him off, looked at him and replied "What if Doofenshmirtz says what Locogisu said, about not only your Host-Family, but your Platypus Family?" Perry stood there in silence, "Exactly." I return home, it was late, "Oh, there you are Sheila!" Thomas exclaimed, in jumped in his bed, "Oh you want sleep in my bed?" Thomas asked "Well good night girl.", I sleep under his arm.
