Health-bars were standardized with Yie Ar Kung-Fu but it was saw first with Kung-Fu Master in 1984.They all steal key mechanics from it. Super meters, health-bars, characters automatically turning to face eachother, advanced button combinations that combine what would have been basic punches and kicks into a more powerful and distinctly different attack. All are as much or more a bespoke creation of Street Fighter I and II than throwing a sphere was in Pokemon.
Super meters didn't exists in Street Fighter I or II... it was added in Super Street Fighter II Turbo in 1994... said that Samurai Shodown is the one that innovate being the first game to have "super meter" in 1993.
Advanced button combination were not started on Street Fighter either (but Street Fighter popularized two move sets used Hadouken "quarter-circle forward" and Shoryuken "Z").
Street Fighter key and most famous signature is Hadouken created by Takashi Nishiyama in 1987.
That is something no other game can direct copy (like Pocketpair did with the pokeball) due the copyright and design considerations.
You can do fireballs or projectiles with different design, animations and/or different moveset.
But a similar projectiles with the fighting doing the two hands opened position using a 90 degree with the quarter-circle forward motion and punch input... you can't.
