A/N: Okay here is chapter 4, I don't know how this chapter is going to go yet. I am kinda going to wing it with this one. Sorry if you guys don't like that but I didn't think too much about what I wanted to do with this battle, since I originally planned on having all the metarex leaders fight this. This chapter will tell you why Dark Oak is back.

--With Shadow, Cosmo, Mira and the mystery person--

When they appeared they found themselves in a forest and they could see Sonic and Knuckles. But no sign of Dark Oak or the Chaos Emeralds. They rushed foward to Sonic and Knuckles to check on them. They felt a very weak pulse on both of them. Mira frowned, "This isn't right. I am happy they are still alive but if what I think happened happened then they should be dead."

Shadow turned to him, "What do you think happened?"

Mira said, "If he has acheived his super form already we are too late to win this fight. We had to use the Arcane crystals to beat him before and they aren't powerful enough to take on a super form, but we were able to draw the power of the chaos ermeralds out of him and combined it with my hyper form." He said.

Cosmo who was watching the interaction between the two and then they stopped talking and looked behind her, before she turned around. She felt someone wrap their arms around her and she screamed and stomped on the person foot. She turned around, and felt her eyes well up with tears at the sight of who it was and she collapsed into his arms sobbing.

She couldn't believe it he had been gone for over a year now, since she had seen him. "Tails!! Thank god! Your alive!" And just sobbed into his chest.

Mira smiled, so all hope was not lost yet. He walked up to Tails and Cosmo and said, "Hi Tails, its good to see you are alive. we can still stop Oblivion Dark Oak. But first we need to get Sonic and Knuckles some help."

--Back at Tails and Cosmos House--

Tails hadn't been home in three years, it didn't look any different. He was in the Kitchen downstairs waiting with Mira as Comso tended to Sonic and Knuckles. "So Mira, who are you exactly?" Tails asked.

Mira shook his head, "All I can tell you is that I am from the future, where Dark Oak won against Sonic and Knuckles but he killed them. I was the one who stopped him finally because of a crystal that I was born with. Noone is sure where it came from but with just one peice of this crystal you can use chaos control. There are eight peices to this crystal. It took me using only one to beat Oblivion Dark Oak." He said.

Tails then asked, "Do you know how he came back? I thought he was destroyed."

Mira nodded, "He was destroyed but the essence of evil that was in that robotic armor was too powerful, its pure evil that lives in that armor now." (A/N: For those who can't guess what I got this from I got this idea from Soul Calbur 3 with Nightmare and Sigfried.)

Tails sat back studying the kitsune in front of him, "Why did you come back to our time? If you won I thought it wouldn't matter."

Mira sighed unhappily, "Well the thing is I don't want your timeline to go through the suffering mine did. When you, Sonic and Knuckles were killed, practically all hope was lost. When Shadow arrived after so many years being gone it helped greatly. He had dissapeared after Sonic and Knuckles died and they had found you dead. My mom was devastated along with all your friends." Mira said carefully.

Tails then asked, "Who was your mother Mira? And why do you look like me?"

Mira only smiled, "You will find out when its time for you to find out who my parents were."

They suddenly heard crying from upstairs, and Miras eyes opened wide in shock, "No it can't be" he said.

Tails looked at him weirdly, "What do you mean?" He asked.

Mira just shook his head and stood up, "It looks like you are going to find out who my parents are sooner then I thought." He said.

--Upstairs in a room--

When Tails and Mira came into the room the crying was coming from, Tails was expecting to see Cosmo crying over Sonic and Knuckles but what he didnt expect was for her to be sitting in a rocking chair holding a young baby. This made Tails heart wrench. She had moved on while was gone.

Cosmo looked up and realized she wasn't alone, "Hi Tails, hi Mira." She said kinda nervously.

Mira looked at her and said, "You know who I am don't you Cosmo?" He asked.

She nodded and answered, "Yes but I don't think you should be calling me by my first name anymore since it will be revealed now." Mira nodded at this and told Tails to sit down. When Tails sat down, Mira said. "As she already knows, I don't know if you have figured this out. But I am the last of the seedrians in my time, my mother was killed on the day the final battle with Oblvion Dark Oak." he said

Tails was getting kinda impatient now, "What does this have to do with whas happening right now, it looks like Cosmo moved on and had a baby during these last three years." He said.

Cosmo sniffled a bit at this and Mira got mad, "She didn't ever move on, the baby came from the seed that was given to you by Uncle Sonic! Just like I did dad!" He shouted.

A/N: I am on a goal right now to update all my stories in the next few days. Sorry if this chatper sucked but I have a preview for a chapter coming up soon not sure when but this is planned to happen soon after dark oaks defeat.

Preview:

Cream and the others were by the master emerald celebrating the 6th anniversary since the metarexs defeat when the master emerald started glowing. Then they noticed something strange appearing inside of it.

There was a shadow coming out of the master emerald, and when it came out entirely, it had the appearance of a teenage rabbit. he walked up to cream and hugged her.

She was shocked and pushed away from him, "Who are you?" She demanded.

He looked puzzled at first then said, "Thats right you don't know me in this form, but I was the robot you called Emerl." He said.
