my headcannons on how the flash fam uses their powers
jay- didn't have the speedforce until later in his career so doesn't really use it much in his fighting instead he'll quickly disarm someone or skid across the ground to trip someone up - his fighting style consists of tackling to subdue and sidesteps to dodge as he was a college American football player
barry- had the speedforce but didn't understand it as well as wally did so he could vibrate through Walls and make them explode with the correct frequency he'd do the spinny hands tornado thing and other tornado-y things more than the other flashes he would often throw lightning by getting a good run up and then stopping suddenly and whipping his arms forward to have it flow past him
wally- taking inspiration from young justice he couldn't really phase through walls and wasn't as good running up walls or with the tornado-y stuff so when he became the flash and became so powerful with the speedforce he never really learned he's the best with the lightning and can produce it at will and since he's the fastest he can go around buildings faster than the others can phase which is always amusing
bart- because he was born with the speedforce and spent his whole (three years of) life developing it it's the most defined- he doesn't cause explosions by phasing he just vibrates his hand puts against a wall and channels the speedforce into the wall and then there's these pulses (heh see what I did there) that go through it before it explodes- Bart has the most creative ways of using the speedforce hence the speed clones- sidenote his powers manifest as pulses rather than lightning (except for the lightning trail behind him) e.g when he throws the speedforce energy it is in these circular blasts until it makes contact with a target then it turns into electricity
Wallace- he's the newest with the speedforce so his lightning is the least refined and the most red and it crackles off of him in the largest amounts when he uses even the slightest amount of his powers- he can control his friction in a way the others can't making it so he can slide against the ground like an ice skater (which is how he runs mostly so he's the most elegant) or he can become completely immovable at a moment's notice (not like he can't be pushed but when he'd be running at full speed he can just stop completely) so he can run on walls the best and when he runs he leaves sparks behind him and even after his lightning there's a glowing red trail of sparks that follow him everywhere and because of this he grafts his emblem wherever he stops a crime as his signature - also as older wally can steal speed Wallace can imbue things with the speedforce temporarily giving his allies a speed boost or making a vehicle a speedforce construct (like older wally does for his suit or hot pursuit has his bike)
I'm gonna make a part two later with irey jai the tornado twins Jesse etc
