Megaman X could throw hadoukens and do shoryu’s in the snes games. And Megaman has a shoryu in the VS series as well.
Magmar Dragoon has akumas move set and prayer beads.
Zangief apparently stole mike haggars spinning pile driver or something, maybe it was the other way around, move could have been the lariat.
Everyone knows Dan is a gag take on SNKS Ryo being blatantly based on Capcoms Ryu, But now Dans sf4 self has the Haoh Gadoken or whatever which is a hilarious version of Ryos super fireball.
That one teacher in rival schools has all of the shoto moves but kinda toned down (like just a spinning hop instead of full on TORNADO KICK, YEA)
Ash Crimson is like a gayer version of Remy who is a fagged up french version of Guile. Guiles moves have been ripped off maybe more than shoto moves by other companies.
Fighters History feels like a weird version of ST where everyone traded moves around for a while.
The amount of shoto-related (any combination of fireball, shoryu, tornado kick) characters that have been playable in SF (including Alpha and EX series) : 11. Ryu, Ken, Akuma, Dan, Sakura, Evil Ryu, Allen, Kairi, Sean, Sagat and Gouken
Sho from Breakers is my favorite Shoto-clone.
Morrigan and Lilith and basically shotos too, and they will never get new sprites so I vote morrigan for most re-hashed character of all time
In conclusion, Capcom are self referrencing bastards but we all love it because it shows they care (kinda, re-using the shoto formula is almost the opposite)
