Guess I'm going with classic.
King, the robot rebellion leader
(You gotta tell us what's the max stat points)

okay Classic Mode time.

(I think that the max stat point is 100 to 275.)

He was outside of the Elemental Dormitory, it is pretty big place for anyone to come and
there is 2 section pathways outside and the 2 other section pathways inside. So King goes inside the place
and boy on the side of the dorm coloured doors to each Guardians as the blue door was unlocked while the other doors was locked, needing a key to open it

Ok.
King's stat points:
HP:65
ATK:60
DEF:100
SPD:50
King looks at the doors, wondering why he got there. He looks for any useful items in the surroundings before entering the door.

Oh... Someone was there, asleep on the blue bed with the burrito blanket, gotta be quiet while this guardian was asleep

???: *asleep* Zzzzzzz

King tries to find someone to battle in order to get stronger.

???: *rolls around a bit on my bed until fall down on the floor while asleep* Ouch!

Water Guardian falls down on the floor and groans in pain.

(yep I was not being prepared while asleep)

You'll do.
King challenges the recently awake Elemental Guardian!

???: eh?! *coughs a bit, being awaken up while getting up* what are you? I am A-Alicia by the way. You can tell that my eyes are tired out because I played games like too much.

Alicia (Me)
HP: 55
ATK: 50
DEF: 120
SPD: 50
Weaknesses: Electric and Nature

I got ready to fight, using the move called Water Breath, dealing a decent damage (25) to King

King puts up his shield, meaning any attack you use will not work and you'll take 5 damage as a recoil.

ah! that hurts a little... *I yawns constantly and swings my Water Hammer*

My yawning sounds annoyed King a bit

(Bruh, you literally hurt yourself)
King defends the attack and his shield turns it into an energy shot, dealing 5 damage!
King then calls one of his soldiers, Cold Man!(also suggestion: don't see much sense on Alicia being weak to nature, maybe freeze because part of her body is pure water, and her water freezing difficults her movement?)
Thanks for the recolor, father! What's my mission?
Cold Man creates an Ice Wall to block projectiles!
(Tip that works for all roleplays: Try to be creative when choosing attacks, for example, you can knock Ice Wall into king if you use Water Hammer)
Cold Man
HP:75
ATK:75
DEF:75
SPD:50
Weapons: Buster Shot Freeze buster Ice Wall Freezing Floor
Item:Cloud Creator: Cold Man makes a cloud mecha out of his freezing temperature
King's Weapons:Buster Shot Shield Buster X-Laser King Axe
Item: King's shield: When not attacking, put up a shield that resists all attacks and fires a small shot when attacked.
Cold Man weaknesses:Electric and Impact, resists flamr and affinity to freeze
King weaknesses: No weaknesses or resistances/affinities.

Me: grrrrrrr! *I swing my Water Hammer at the Ice Wall, knocking it back to King*

(That sounds good)

(However you also need to think about the consequences of your action, bruh he has a frickin shield walls wont change that)
King reflects the Ice Wall Alicia knocked for 5 damage again!!!
King finally puts down the shield, using his X-Laser(who is electric-cored thus meaning it's Alicia's weakness) and déaling a tremendous amount of damage, probably defeating her!

Noooooo!! *fallen down defeated*

The key must be somewhere within the Alicia's dorm room, it could be either on the desk table, food cupboard, mini kitchen or the drawers

King then grabs all of Alicia's items, including her Water Hammer.
Checkmate.
Cold Man looks for the key...

You found the... Energy pellet within the above drawer from the desk table. King sees the laptop that is still on and had the game that the someone played the game before she left to go out with her friends... Want to smash it?

(okay laptop can be optionally smashed... However, it will only make someone go ballistic if do so)

King decides that instead of smashing the computer, he should hack it.
There might be useful information for making a world without humans!

alright, you choose not to smash the laptop instead hacking it. Cold Man searches the key from mini kitchen that he found the weapon capsule to the last food cupboard which he founds the key from the above cupboard shelve though there's so many snacks like sour candy strips, gummy bears and instant ramens.

Cold Man stores all of the food inside himself, he's a literal fridge after all.
King searches for useful information on the computer.

he found some of info in the laptop. Some of the folder files are useful and others are junk and oh there's one folder file on the screen that has the good info and some lore about Virus Robots because the elemental lore folder file is in other guardian's room

Virus Robots Lore
Back in 1960s, their population used to be that high amount of those robots, their place of homeland
is unknown to this day but suggested that they lived in British to the Germany until they are hunted down
by some peoples and that year later, the Virus Robots began to move to their former place to other places and
lived for their safety. The First Virus Robot was Medley who was said to be very destructive and venomous to humanity in the world where her venom spit is enough to cause burns and could bite them with her sharp teeth as everyone was quite feared of her more than they are feared of venomous snakes
