So be it...
==============
Mari was just about give the mercy killing blow to Xiroey, when suddenly a few scattered dark bolts rain from the sky mixed along with some magical arrows, both light and dark, mixed with scattered flames.
"What the--", reacted Mari.
Frostwraith rode his Hydreigon and accompanying them were Pit and Dark Pit, as well as Cynthia and Alder riding their Braviary and Volcarona respectively.
"You just can't do something hideous like that, Mari!", yelled Frostwraith.
"Frost, what's going on here?", reacted Xiroey.
"I found a possible solution in one of my magic books... you, Xiroey... are cursed!", said Frostwraith. "A rare type of hex... thankfully, I had just finished reading a book about curses... and possession."
"Cursed? What do you mean with that?", inquired Richard.
"Allow me for a demonstration...", calmly said Frostwraith, snapping his finger. Richard suddenly felt a horrible headache and a lot of fever. Launching a healing spell at Richard, Frostwraith cured him of the condition.
"Oww... my head...", said Richard in pain.
"That was a lighter hex...", sighed Frostwraith.
"A lighter hex? Where are you going with this?", inquired Mari.
"What Xiroey has is nothing more but demonic possession of the highest order. What I did to Richard was to give him nearly fatal fever, but it's like I said, it was a low level hex.", explained Frostwraith, calmly.
"So what do you pretend to do?", curiously asked Mari.
"Drive whatever fiend inside of Xiroey out... keep your distance everyone... this could get risky... and I mean very risky.", warned Frostwraith.
"I don't like the sound of this...", said Sonic.
"We're talking about dark magic here... it's among the most strange magic around. It's not evil, but it's certainly no toy... see all those scars in my face? These aren't there for no reason.", further explained Frostwraith, who was as serious as ever. "We're dealing with something dangerous here... it could cost our lives... and killing Xiroey would only set free the...
thing dwelling inside of him."
"Okay...", reacted Mari.
"It's time to start the purge...", grimly said Frostwraith. "I warn again... keep a safe distance. Except you, Xiroey."
Everyone backed off as Frostwraith demanded.
"Frost, what in bl--", Luco began.
"Silence!", rudely interrupted Frostwraith. "I need to focus..."
Xiroey standed there as Frostwraith ordered.
"NOW!", yelled Frostwraith, launching a bolt of light energy at Xiroey, hurting him.
"What the--", reacted Mari.
Xiroey's eyes began to glow again.
"Oh, no...", reacted Luco.
"Light Chains!", yelled Frostwraith as he binded Latios in light energy. "Expurget!"
Latios let off a roar which indicated pain and anger at the same time. Frostwraith remained as focused as ever.
"Damn... this is not working as I expected...", muttered Frostwraith.
"Arrgghh!!", roared Latios.
"Now... come! Face me, demon! Devour me! Feed my anger!!", yelled Frostwraith even louder, causing the black Latios to charge at him with full strength.
Frostwraith used light magic to stun him and ordred Hydreigon to use Draco Meteor, severely hurting Latios, who got back to fight as if nothing happened.
"Everyone, stay out of this!", yelled Frostwraith. "This is getting dangerous!"

Frostwraith was aided by Hydreigon in the battle.
"I need your hand, Chandelure!", said Frostwraith, sending his Chandelure.
Latios merely roared and charged at Frostwraith himself, who got knocked down.
"Frost!", yelled Luco.
"This is nothing! I will not be defeated by a demon like this! Now, do your worst, fiend!", said Frostwraith, drawing his sword.
Latios prepared a Hyper Beam move. Frostwraith merely stood there, waiting for Latios to fire the beam.
"Come! Face me!", provoked Frostwraith.
Latios fired and Frostwraith quickly conjured a magic mirror, deflecting the beam back at Latios, who needed recharging.
"Not quite so tough now, are you?", further provoked Frostwraith, causing Latios's rage to build up.
Latios was now fully recharged again and prepared another attack.
"Not so fast! Hydreigon, Draco Meteor!", yelled Frostwraith.
The attack interrupted Latios, giving Frostwraith time.
"Chandelure... Shadow Ball...", ordred Frostwraith. "Partners... I need you to buy me time... hold him off has best as you can..."
Chandelure kept attacking Latios by firing Shadow Ball attacks. Hydreigon attacked with such ferocity that some members of the group questioned if Frostwraith intended to kill Xiroey.
"And now... it ends...", muttered Frostwraith. "Dual... Dragon Blast!!!"
Frostwraith shot two dragon shaped projectiles, one made of pure, bright light, the other made of pitch-black darkness. The combined spell hit Latios hard, knocking him unconscious. In fact, almost dead.

Frostwraith began conjuring strange sigils which seemed to be made of arcane energy. The sigils made their way inside Latios's body causing it to shake uncontrollably in a way unhinged and unnatural.
"Two souls... one body bound to them...", whispered Frostwraith, with his dark red eyes starting to glow. "My first use of soul manipulation magic... I can only hope..."
Frostwraith began to hold a strange bluish purple energy ball, which seemed to have souls orbitating around what seemed to be a core.
"Soul Split...", muttered Frostwraith.
The energy ball slowly travelled to Latios's shaking body. Frostwraith's heartbeat was very high, he was starting to get dizzy. Upon contacting Latios' body, it suddenly stopped, only for it to shake even more crazily and suddenly a dark cloud popped out from Latios' body.
"Now, this truly ends... Lux, purget hoc pe fende... Curarent confractum istum corpus...", calmly said Frostwraith, while conjuring a light ball in his hands. "Finem huius tormentum!"
The light ball materialized into a sharp spike, which stroke against the dark cloud, causing it to blow up.
Shortly after the explosion, Frostwraith fell onto his knees and began to struggle to breathe.
"I... it... is... ov...er... uurgh... I... did... it...", said Frostwraith, coughing heavily between each word he spoke. "I... need... rest..."
Frostwraith fell unconscious.
---------------
Few minutes later, Xiroey woke up, wondering where he was. He was back at the group's camp. Now possessing a seemingly lighter color, he felt strangely optimistic.
"Xiro!", reacted Mari.
"Mari? Is that you?", reminded Xiroey. "I'm sorry..."
"You're alive now... that's what should matter for now... that mysterious Frostwraith fellow has nearly gave his life trying to save you from whatever it was tormenting you."
Frostwraith was lying on the floor, still unconscious. His body felt heavy and there were no signs of breath nor heartbeat.
"Is he dead?", asked Pit.
"He's holding on... but his vitality is very weak... he has really overdone his use of magic.", telepathically responded Palutena. "He will be fine, though."
-----------------
Few more minutes later, and Frostwraith woke up, all worn out.
"I hope that's the last time I have to take things so far...", said Frostwraith. "I suppose I should meditate for while..."
"That was quite the achievement there...", said Dark Pit.
"It was nothing...", responded Frostwraith.
Frostwraith got up and slowly walked to Xiroey.
"Frost...", reacted Xiroey.
"Hadn't I interrupted you that time... and your death would've been in vain... you shouldn't have problems with that thing again... but, there might be traces of it flowing through your body, so I can't say anything for sure... urggh...", said Frostwraith before rolling his eyes and collapsing again.
"Frost!", reacted Xiroey.
Frostwraith opened his eyes again.
"I am just too weak now... I can't be doing this effort to stay awake... but... I have a proposal... for... you...", weakly said Frostwraith.
"Proposal?", questioned Xiroey.
"Like... I said... there are... traces... of that... thing... in your... bo...dy... I can... teach... you... how to... control that power... just... let me... rest... for... now...", weakly said Frostwraith, before falling asleep.
"Control that power...", repeated Xiroey, before starting to consider such possibility.
==============
So... tell me what you think about this part, will you? If it goes against something... tell me, okay?
Also, let's not forget that the tournament is still going! The second semi-final is Cynthia vs. Luco, with the winner facing off against Frostwraith in the grand finale.
And the question is (considering everyone's okay with this): will Xiroey accept Frostwraith's offer to teach him how to control those shadowy powers?
