Quirks from Another Dimension: Super Smash Brothers Quirks

Final Smash

A quirk based on Smash Balls and the Final Smash

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

Quirk Description:

Final Smash is an Emitter-type quirk used by Midoriya Izuku. When under high amounts of distress and/or pain, the user gets shrouded by an aura of multicolored flames and their eyes turn into a shade of yellow. The flames are purely cosmetic and don't act anything like normal flames. When the user touches a person with the intent to share the aura, the affected person suddenly gains a huge boost to their power and speed, both in their bodies and quirks. The power increase from the quirk is similar to the effects of Trigger, though for a shorter amount of time and without any negative side effects. This power-up can then be used by the affected person to create a powerful 'finishing blow'.

With OFA:

With the power of One for All boosting Final Smash, the quirk no longer becomes a purely support-based quirk. The user himself can now benefit from the aura created, as when activated it significantly boosts his own base speed and power. Additionally, the user can now expel the aura on its own without having to calm down first by unleashing a 'finishing blow' of their own. This can either manifest as 1.) a powerful volley of kicks and punches for close combat, 2.) a series of slashes and slash beams from a weapon for mid-range, or 3.) a massive singular beam of energy for long-distance.

The world seemed to blur around Izuku since All Might left the rooftop to drop the sludge villain off. He wasn't sure how he got off the building or even how long he'd been walking on the unfamiliar route home; simply putting one foot in front of the other in a dazed autopilot.

'Come on Izuku, you should have expected this,' He thought self-deprecatingly. His hands shook with emotion, small wisps of multicolored flame escaping from his clenched fists. 'They told you. Everyone told you you wouldn't make it, so why would the Number One hero say anything else?'

"Your quirk's so lame! You have fire and you can't even DO anything with it!"

"You're weak Deku! You're as useless as your quirk!"

"I'm sorry, young man. But with a quirk like yours, it's too dangerous to be a hero."

He forced himself to control his emotions, stamping out all the feelings of hurt and rejection he was feeling. The fires flickered away, leaving his hands and the backpack straps he was clenching completely untouched.

'They're right, I can't make it as a hero. Not like this.' Tears threatened to fall from Izuku's eyes as he shook. 'Maybe it is time to give up on my dream. Mom would be happy I wasn't in any danger at least..."

But before Izuku could walk away, a loud cacophony of sound reached his ears. He turned to see a large crowd blocking the street, all looking at what seemed to be a growing fire in the middle.

'A villain fight? Maybe I can take some notes to be-' Izuku stopped himself. 'Right... I can't be a hero... but I can still check out the fight, right?' He turned and walked into the crowd. He craned his neck to see what the fight was about when his blood went cold.

'Oh no, that's the Sludge Villain!' The same villain who'd attacked him hours prior was now at the center of the fight. Fire erupted from the villain's make, as he taunted and attacked the present heroes who were just standing around as he rampaged. 'But All Might already caught him! How did-'

The jump. All Might. He didn't have the bottles with him when they landed! Izuku choked back a cry, his flame coming back as his eyes flickered into a golden glow. He barely heard the crowd's commentary of the fight, nor did he notice the people next to him shrinking away from the flames. 'It's my fault. Stupid, stupid! I made All Might lose the villain with that stunt!'
