The time has come. Once again, Frisk and Twilight stand against another great challenge of their lives. It's not the biggest compared to the final battle of the pony war, but still, going up against an immortal being is no easy task.
For convenience, Twilight turned into a human for this fight. The two got the best gear they can possibly get through their powers, and a day after their final, casual chat, it was finally their turn to face the genocide king. After a few months, three failed attempts, the two set out for one last time. Right now, Spike, Frisk, and Twilight are the only ones left representing ponykind. If they fall, ponykind will be eradicated from history.
'Are you ready, my friend?' Frisk smiled.
Twilight nodded. 'I was born ready!' She gave her a high-five.
Spike was at the control panel, so he gets to communicate with the two while the fight goes on.
'I never thought this guy can kill all of our kind,' Spike said sadly.
Frisk sighed. 'We tried to stop him... However, he is too strong. We have hidden our powers away from him for a while. It is the time he deserves the punishment he should have accepted a long time ago, and he will see just how strong I have gotten in all the years I left him. There's no chance for Felix to win.'
'This is the moment of truth. Either we'll persuade him to show mercy, or... Well, you know what I mean.' Twilight explained further.
'So... I guess this is goodbye... I'll be okay if you both fall. I wish you both good luck,' Spike said.
Twilight picked him up and cuddled him tightly into her heart. 'I'm going to miss you, my sweet buddy.'
'(Giggles) I will too. You've been my pet for a while as well,' Frisk said. She lightly kissed Spike goodbye after she said that.
They put him down again, and he ran back to the control panel after they reached the door of the castle.
'Let's go and end the suffering,' Twilight told Frisk, holding out her hand.
She took her hand, and the two were lightly holding hands as they walked to the royal castle in Canterlot, where Felix was waiting for them.
As they finally got to the throne room, they both knew one thing: Once they go in, there is no turning back. Only one side will stay alive in the end.
Frisk looked at the door to the room. 'I remember this scene...'
Her friend nodded. 'Yeah, you were only fifteen when you faced Gromiz. But now... We have grown so much through the years. Our friendship grew much closer as we went on.' She touched Frisk's shoulder. 'But, I just wanted to say something, just in case we die. Honestly, you have always been the most beloved friend of mine. Of course, Nathan's my boyfriend but... You mean a lot more to me than just a friend. You may not know, but I missed you so much when you weren't with me in those few years.'
Frisk did the same thing with Twilight. 'It feels if we share the same soul sometimes. We're a destined pair.'
The two friends hugged, and both touched the handles of the door, ready for their last fight.
'Open it on three.' She said.
'One... Two... Three!' They both said, opening the door to reveal the villain.
Inside the throne room, sat the infamous convict, Felix.
'(Sigh) Finally. I was so tired of all this fighting I had to go through with the others.' He muttered.
They both got their swords ready. 'This will be your last fight!' Frisk shouted.
Felix turned to them. 'Don't you still not know I can't die? It's useless to fight me. You will still lose. You failed numerous times already. Just give in, and let me take your souls.'
Twilight stomped the floor with rage. 'No, never! We'll never give up trying to stop you, no matter how much effort it takes to persuade you to mercy us!'
The moment she said the word 'Mercy', Felix started to feel awkward, and he felt as if he had an extremely painful headache. Suddenly, his body went dead for a bit, and some kind of ghost came out.
'Frisk? Are you there? It's me, your best friend.' It said kindly.
'Shut up! You are not my friend anymore!' She angrily responded.
'Please listen to me.' It said. 'I am the soul of the real Felix. Dark magic has consumed me into this human being. Now, I am nothing now but a spirit. The only way to free me is by doing exactly what you guys just said.'
'You mean... We have to mercy him and show him true friendship?' Twilight asked.
The ghost shook his head. 'It's not that simple. Only when you have the golden soul... That is the only way he can be affected by your kindness. Then, if you can break his heart with all of your warmth and love, you will successfully give me the chance to escape his soul, and free myself from this curse.' He realized something. 'I don't have much time left to tell you guys about it. Just remember what I say, and good luck to you both.'
As soon he finished, he was sucked back into his body.
'What was that!? You didn't hear anything!' He yelled.
'We know your secret... And we will force you to show it!' Frisk yelled back.
Both Frisk and Felix were furious at each other.
'Fine then! Let's fight, shall we?' She asked.
Felix started a little song.
'So much blood...
So much pain...
Just to see...
My friend again...
Oh, my friend...
I'm sorry...
Now you must face the...
Genocide king!'
He was ready to fight when he had one last thing to say.
'(Chuckles) Frisk, it's been nice to meet you again. Goodbye.'
He pulled out his swords, and the two sides started to fight, while a song was ringing in their ears.
'This will be...
The last soul I need.
I will not,
Accept your mercy...
With your pain,
My heart will fulfill...
It's final destiny!'
'No, you'll fall,
You'll pay for your crimes.
You must die,
We'll claim victory!'
As they sang, the voices of their past friends were counting on them for the future of ponykind.
'No more pain,
Our saviour be!
Come on,
Frisk and Twilight!
They will stand tall,
It's come down to this,
The future's counting,
On our last warriors...'
'Can't hold back...
My breath is all gone,
My vision is blurred...
I'm asking myself,
What have I done!?'
'The pain you have caused,
Our friends you have killed,
You must pay the price,
You shall burn in hell!
You changed their lives,
You broke all the laws,
We will see the sun!
'Frisk... I'm so sorry!
You killed everyone,
Now it is your turn,
They'll never give up,
They will make us smile!
We cannot delay,
And after this fight,
Someone has to die,
And I hate to say goodbye...'
Suddenly, the sound of the real Felix was ringing in their ears as well.
'Should I embrace...
This last chance that I have?
Should I erase...
All the ponies I've killed?'
'Maybe you didn't mean to,
And we could forgive you.'
'Could have been just normal,
And go on with my life.
If we could reunite,
How good that'll be!
Relive the old days,
As best friends for life.'
'NO!
That's just me dreaming,
I need to wake up!
My heart is hungry for it,
Your souls will be mine!
And when this fight is over,
I will see the sun!
And all the memories that we made,
Will all be lost!
I'll have the last laugh!
Farewell, my best friend!
For tonight...
The villain has won!'
In the end, Felix had the upper hand, and Frisk and Twilight were already almost dropping dead. Their past partners were all afraid they'll lose, but it was no surprise.
'No, they're losing!
He's gonna win!
They have fallen!
It's all over!!'
'Time to finish you!' He shouted, performing a huge explosion spell against the two and sending them flying to seemingly oblivion in the sky.
Both of them had a long scream as they flew, and it was seemingly all over.
'Finally... I have won this battle,' He sneered. 'You know what, I don't need their souls. I have already proven myself as the ultimate fighter. I'll just wait for them to perish, now that they are defenseless. There's no chance for them to escape the added poison spell in that explosion. And THEN I will take their souls and become a god.'
And so, Felix had a very loud evil laughter, thinking he has won and eradicated the ponykind.
Meanwhile, on the other side, Frisk and Twilight were being blown far away by the blast. Crashing into her castle, the defense had failed once again.
'I... I lost... How could that happen?' Frisk muttered to herself. She wanted to turn to her friend. 'Twilight, we have to go back and stop him!'
But there was no response from her.
'Twilight? Hello? Oh no, are you dying!?' She panicked.
'(Grunts) Frisk... Over here...'
She immediately ran to her, who was on the other side of the room. The princess was severely hurt, and the chances of her dying right here are high.
Twilight smiled. '(Chuckles) Frisk... That was... a great fight, wasn't it?'
'What!? We lost!' Frisk yelled.
'It was a great final fight. My time is running out now. I... I'm sure you'll be okay. I just know it,' She said, with blood dripping down her face.
Frisk hugged her friend tightly and cried. 'Twilly.... Don't leave me alone...'
'There is one last thing I can do for you, though.' She said. 'Have you tried the fusion spell you've been working on? If you can use the spell on me, and fuse with yourself, you will have much more power than you will ever have. The only problem is, doing so will kill me, as I am already very close to dying right now.'
The girl thought about it for quite a while and finally accepted the idea. Holding back all of her tears, and performed the spell on her friend. The second before the spell was initiated, Twilight waved Frisk goodbye, for one last time. When it was complete, the girl had changed. Her mane was a mix between blue and purple, and now some parts of her skin are yellow, some are purple. It sounds weird, but she didn't care.
The new girl looked at the perished body of the princess.
'Twilight Sparkle... I promise I will avenge you! I will fight him for you, for all our friends, and for the future of Equestria!' She proclaimed. Then she busted through the ceiling of the castle, and had one thing to say, before dashing over back to Canterlot castle.
'Felix... You've slain all my friends, now I will find you, I will force you to give in, and I will not stop until you are free!'
