A/N: Okay since the way I made Ruby into the king of the monster's was very Shin Godzilla like, I went back a gave her a mix of Shin Godzilla/ Legendary Godzilla, needless to say she can easily kill Salem cause radiation sickness can easily kill her, she can throw hand's with the brother god's as well.
Also i decided that since Ruby is constantly evolving she will be a futa, her evolution is fueled by her energy and desires so she can actually be a futa, plus the fact that technically she can reproduce asexually with her evolutionary abilities.
Also this is going to be GRAPHIC! Shin Godzilla has my pity and so does Ruby since she's a mix of Legendary and Shin Godzilla, she will be evolving in some way every chapter very painfully too.
Ruby felt cold water rush around her new massive body, the cool crispness of the liquid flowing over her hard jet black skin. She was still following the transport bullhead to Atlas, hoping they have a chance to fix the things the blast had done to her body if she can't do it herself. Ruby used her tail to swim through the water's effortlessly, she felt the water rush through the gill's on her neck, giving her the oxygen her body still needed through the rushing water.
Ruby flashed her dorsal plates as a bright purple display, before she started to pick up speed in the water, going much faster than the bullhead she was following in a matter of minutes, she was feeling just how powerful the bomb blast had truly made her. She had become the strongest being around the world, no Grimm could ever truly hurt her again if she didn't kill them all, she let out a thunderous roar in the deep blue water as she swam in a terrifying visage.
On the bullhead now following Ruby through the ocean towards Solitas, the captain was watching with awe as Ruby swam through the water with such fluid ease, her giant dorsal plates gliding through the top water so easily. As everyone on the bullhead watched Ruby swim through the open hatch, they did not notice the sonar contact coming off the left side of the airship, its bright red dot pinging on the display in the cockpit with a very faint shrill screech.
Ruby however noticed this new threat as she let out a thunderous growl at it, sensing it through her new bodies biological sonar system that could see everything around, she swung her massive Body heading to the somewhat smaller sized threat coming in fast. She collided head on with a 50 meter leviathan Grimm and she wrapped her tail around the giant Grimm, dragging it into the dark murky depth's of the ocean.
She gathered the excess nuclear energy in her body to her throat, her spines glowing a fiery neon purple as her body pulsed with power, she kicked the sea Grimm hard upwards into the water, before letting out a massive blast of purple energy from her throat into the Grimm.
She immediately felt pain in her throat and organ's from expending her nuclear energy, it was burning her insides with an unholy amount of pain, she needed to use her body more and her atomic breath less or she will die again like before.
Ruby watched as the Grimm was atomized completely by the blast, the purple beam traveling through the water into the sky with a deadly shrill whistle, with the people onboard the bullhead screaming as the blast nearly hit them from below.
Ruby swam back to the surface and the bullhead that she needed to follow, getting back into swimming towards her goal in Atlas and maybe getting her old life back. Several Atlas warships had now surrounded Ruby as she swam to keep her from attacking anything, keeping up with her as she swam to that wintery continent of Solitas.
Ruby soon made landfall upon Solitas, letting loose a thunderous God like roar as she stood up to her full height and started to walk slowly to the floating city of Atlas.
