Aspirations, I have some

You point and shout at one creature, reminding them about the kind of action Hero they always wanted to be. They burst into lightning, get spectral sunglasses and for the next 1+1d4 rounds, they turn into that Hero.

When empowered, The Hero gain these effects:

• "Terminated.": During the transformation, a burst of lightning erupts. Each creature of the Hero’s choice within 5ft. must make a Constitution saving throw against your spell save DC, taking 2d10 lightning damage on a failed save, or half as much on a success.
• "Welcome to the party, pal.": Immediately after the transformation, the Hero can take one Action and one Bonus Action. This occurs before the next creature’s turn in initiative order.
• “I'll give you a war you wouldn't believe.”: On each of their turns, the Hero can make one additional Weapon attack as a Bonus Action.
• “Do I feel lucky? Well, do ya, punk?”: The first attack roll each creature makes against the Hero on each of its turns is made with disadvantage.
• “Smile, You Son of a...”: The Hero adds their Charisma modifier to all weapon damage rolls.
• "There can be Only One": There can be only 1 Hero within a radius of 1986ft. If you cast this spell while another Hero is within that range, the spell slot is expended but the spell fails.

At higher levels: 

Casting this spell with higher-level slots gives the Hero even more abilities:

• 5th Level, “I’ll Be Back.”: The first time The Hero would be reduced to 0 HP during the spell’s duration, they instead drop to 1 HP and can immediately move up to half their speed without provoking opportunity attacks.

• 6th level, “Dodge this.”: The Hero scores a critical hit on a roll of 19 or 20 for the duration.

• 7th Level, "I ain't got time to bleed.": The Hero has resistance to all damage until the spell ends.

• 8th level, “This is my BOOMSTICK!” Once per turn, the Hero can deal an extra 2d8 thunder damage on a hit.

• 9th level, “No sequel for you.”: When the spell ends, the Hero unleashes a final cinematic explosion: all hostile creatures of their choice within 15ft. take 5d10 Fire damage and must succeed on a Dexterity saving throw against your spell save DC or be knocked prone.

"Can we trade in these lives we lead
'cause baby you should see me in my dreams
Fighting assassins off in bullet time
Spinnin' three-sixty degrees
'cause all these movies got me thinkin'
Could i ever be like them?"
