My Sign-in system in Marvel(AU)

Katarina looked at the two items in her inventory, first being the Super Serum(Revised), the system explained that it was like the Serum Captain America got but without any of the side affects, next was the Symbiote(perfected), at first she was happy but then after hearing the system's explanation she had a complex feeling, essentially the Symbiote was the strongest of it's kind but unlike the others it had no connection to anything, but once connected to her it'd be utterly loyal to her, if it somehow got unmerged with her it'd immediately be put back into the inventory. And unlike other Symbiotes that are weak to fire and sound, this symbiote is immune with the only weakness being that of cosmic type energy/magic, as for the HUD, well that immediately merged. Katerina's left eye constantly had a health bar, mana bar, and stamina bar, and the system explained that this was all a pinpoint accuracy HUD, meaning she lot 1 point of health it'd show on the HUD. Katerina was looking at this and thought of something, 'do I have a status?' With a kind of ding sound a screen popped up.

----------------------------------------------------

Name: Katerina Barton Age:17

Strength: 25

Agility: 30

Mana: ???

Stamina: 30

Luck: 45

----------------------------------------------------

Katarina nodded with satisfaction as she looked over her stats, but the smile disappeared as she looked at her mana stat, she wasn't sure if could wield magic or if it isn't showing because she doesn't know magic, either way she put it aside from now. 'System do the sign ins disappeared are they permanent?' 'They are permanent.' Katerina smiled and nodded, 'use one sign in'

'Ding! Host has gotten an ability! The ability is spider-sense!'

Katerina's smile faltered not of sadness but confusion 'I thought I'd need to be like spider-man or spider-gwen to get spider stuffs' 'while certain abilities are tied to the spiders some abilities can be extracted for host to use such as this one' Katerina nodded slowly, taking in the information as she felt her world view shift from a 180 to a 360, she could even sense the fly that was close to the window bathroom, after a few minutes she got used to the sensation, 'system do one more, I'll save an extra for a sticky situation' soon came a ding.

'Ding! Host has obtained a mental laptop! The way this works is that host can summon the laptop with a thought, everyone can see it which looks like a floating ethereal laptop so be careful host! The Laptop automatically connects to any Wi-Fi anonymously. also since Laptop doesn't technically exist, host can hack people but people can't hack host!

Katerina only had one thought while taking in the systems text, 'goodluck to anyone who wrongs me!'

-knock knock knock- "Katerina you okay? You been in there a while!" Katerina nervously flushed the toilet as her first thought then turned the sink on before replying, "Y-yeah dad I'm fine! I'll be out soon!" Katerina mentally slapped herself for not coming up with an excuse other then the dumb act, after actually using the bathroom and washing her hands Katerina made her way back outside where Natasha stood in a almost battle ready stance, she threw Katerina a wooden sword, "I know you prefer a bow like you're dad but I think we should practice close combat." She said while fully getting into a combat position.

Katerina made the first move by taking a low stance while rushing toward going for a side slash, Natasha was momentarily stunned at the display of speed but she came back to her senses and dodged backwards, Katerina grinned as Natasha had done what she wanted as she was mid side slash she quickly changed the direction to do a forward piercing, Natasha was mid dodge when she felt pain in her stomach. After clutching her stomach at the unexpected pain she finally breathed and stood straight up, "Clint you sure she hasn't been learning close combat? If she can get me with a move like that I'm kinda fearful of what she can do with a dagger or just fists."

Clint came out of his momentary daze upon being called by Natasha, "I'm a hundred percent sure I haven't taught her that, maybe she's been watching our sparring sessions?"

Katerina was currently looking at her hands while flexing them into fists, she isn't sure where the skills came from as she hasn't gotten an ability like that yet, but she assumed it was something gifted to her upon reincarnation.

'Did I get some innate abilities while reincarnation' 'Affirmative, The One Above All had gifted you with some basic combat abilities such as, Close Combat Mastery(perfected), Small Firearms Master(perfected), and melee weapon mastery(perfected)'

Katerina was stunned at first but upon realizing that she was literally in Marvel, those skills are needed.

A few hours later and after dinner

Katerina sat on her bed looking at her inventory, deciding now or never she summoned the Super Serum. She looked at the bright blue vial in awe for a minute before taking the top off and downing it, almost immediately she felt her insides heating up and her muscles tensing, 'FUCK! Worst decision to this at home!' Katerina thought as she couldn't scream or else her family would show up. After an hour extreme pain, inside and out, she stood up breathing. She walked up to the mirror, 'thankfully there isn't anything to noticable like Caps transformation, still though, my muscles do seem bigger...shit even mu chest got bigger!? Sigh guess I gotta ask mom for a few more bras, shit wait' Katerina quickly lowered her pants and felt her heart drop, 'fuck fuck fuck! I was fine with six inches! It was easy to hide! How difficult will it be to hide nine almost ten inches!?' Katerina quickly breathes and pulled her pants up and re-situated herself, 'ok ok this is fine, it's not fine! Whatever I'll deal with it with...something I'm not sure how, anyway up next is the Symbiote.'

Katerina quickly opened opened her inventory and summoned the Symbiote, Katerina smiled as it made her think of a slime, "i am you're creator and you will listen to me, if you understand then combine with me" as Katerina finished the Symbiote slime convered all over her body with tendral like fingers, once finished he formed and contorted to her clothing and clinged to her body. Katerina wasn't sure about the closeness at first but then she notice her 'member' was as in the open as before and even her chest was toned down, with a nod of satisfaction she quickly went to work on a superhero outfit.
