#i don't really know how the speedforce works but neither does dc so i will take some liberties

okay so i have been thinking very extensively about a flash family movie à la into the spiderverse

wally west is the main character, he's 14/15 and obsessed with the flash, not knowing that he's his uncle. eobard thawne, in an attempt to strengthen his own powers and take away barry's so he can kill him and replace him, creates a machine that can tap into the speedforce (or something like that). so barry goes to stop him and wally follows him because who would pass up a chance to see the flash in action? barry attempts to destroy the machine but he isn't able to completely dismantle it before it deploys. wally gets caught in the blast, which grants him superspeed and a connection to the speedforce. barry loses his powers and is severely injured from the explosion and when wally runs down to try and help him barry reveals his secret identity and gives wally his flash ring, telling him to run and not let thawne find him. wally obeys but stays behind just long enough to watch thawne kill barry.

the machine's explosion disrupted the speedforce and everyone who had been tapping into it when it exploded gets pulled into wally's universe. this includes an alternate universe barry, bart allen/impulse, jay garrick/flash, jesse chambers/jesse quick, max crandall/max mercury, irey west/impulse and jai west/kid flash, and jess chambers/kid quick (plus maybe don and dawn allen/the tornado twins and jenni ognats/XS but things might get real confusing with the whole allen family tree in one place). they'd all have a bit like in spiderverse where they say "my name is [name] and i'm the fastest [man/woman/kid] alive" and explain their origin stories. it would be funny to see bart and irey bicker over who was impulse first and see wally freak out over meeting his kids from an alternate universe

they all have to work together to defeat thawne and go back to their universes because the speedforce is messed up. wally gets mentored by the older flashes and gains the confidence to follow in barry's footsteps and become his universe's flash (like rebirth wally west) and its all just a bunch of flash family bonding! this is mostly self-indulgent because i want to see all of the flash fam together in one universe
