Multiverse Theory is a BITCH (RWBY)

Helminth

Aj: "In this universe, Jaune and Arthur are scientists that are working on a virus that can deal with the grimm"
S+A: "Oh?"

???: "Test subject Cinder are you ready?"

Cinder: "THEY'RE EXPERIMENTING ON ME!?"
Cinder's glare lands on Jaune and Arthur as they both sheepishly look away.
Adam: "Hmph, Human's being as disgusting as usual"
Aj: "Well Cinder is dying and this may save her life and make her stronger than before"
Cinder eyes light up at the words 'stronger' while Adam just rolls his eyes

Cinder  "As ready as I'll ever be Jaune, just do it."
Jaune nods and pulls out a syringe and pierces her arm and empties it. He leaves the room and the speaker crackles to life
Arthur asked "How are you feeling?"
Cinder while rolling her eyes replied "Annoyed, was that supposed to work instan-!"
Cinder felt like she had pure fire pulse through her very being and had her perception of time slow to a crawl then the screaming started.
Cinder roared in pain and she felt her everything being broken down and rebuilt only to be broken down again

Cinder just stared in shock at her other self as she screamed while Jaune just cringed and Arthur just seemed interested in what was in the vial.

Jaune yelled through the speaker "Focus on a point in your life! Focus on a moment in your life you remember like it happened yesterday and focus on it!"
Cinder screamed curses at Jaune but listened anyway and felt everything go black. Then she opened her eyes and saw herself in her bedroom with another Cinder and this fake Cinder told her she died, that the experiment that was supposed to bring you closer to your goal had killed her and that she was a fool for thinking it would save her. However Cinder just told this fake Cinder to shut up in a nonchalant tone. F.C just stared at her in shock as Cinder continued talking about how she knew this experiment could kill her and how she refuses to die until she accomplishes her goals as the room caught on fire and she stared into the eyes of F.C and F.C smirked and said "Then go and show them who you are"

Everybody just stared at the screen in shock and confusion wondering what kind of virus Jaune and Arthur made

Cinder woke up to the sound of someone yelling "It worked! It worked!"
Cinder still feeling dazed she heard Jaune asking "Are you ok? How are you feeling?"
Cinder finally waking up fully replied "I feel like a haze had lifted off me, I feel...reborn?" Jaune's eyes lit up and excitingly told her to activate her aura and she did so only to feel like she just wore a full suit of armour that fit perfectly and Jaune stared at her in shock and happiness and ran off to get a mirror and told Cinder to check herself out in the mirror and she saw her self in armour shes never seen before.

When she deactivated her aura, the armour disappeared and when she activated it came back.

Cinder looked at the armour feeling like it fit her for some reason while Ruby and Arthur had been sputtering at how a virus could do all that and how it could possibly work.

Arthur clearly feeling nothing but happiness at the fact it worked asked if she wanted to name the armour. Cinder looked into the mirror and smirked underneath the armour and said 'EMBER'
