Since you didn't provide a specific link to the new character ideas for Street Fighter 6, I'll discuss some general concepts and ideas that have been circulating in the community.
: Some fans suggest creating a new character inspired by Urien's moveset, which could include abilities like the Metallic Sphere and Chariot Tackle. This character could be a female version with a more traditional uppercut instead of the Dangerous Headbutt2.
: Sakura is a popular choice due to her fan base. Her inclusion in Season 3 could involve a more mature design, reflecting her growth since her last appearance in Street Fighter V2.
: Although not as popular, some fans would like to see Sodom return as a full-fledged character rather than just a costume pack2.
: There's a rumor suggesting Alex might join Season 3. Alex is known for his wrestling and kickboxing style, making him a unique addition3.
: Fans also suggest introducing characters from diverse backgrounds and fighting styles, such as a Cree Canadian fighter or a new female Indian fighter combining Kalarippyattu and Bharatanatyam4.
These ideas reflect a desire for both nostalgic characters and new, culturally diverse fighters. The inclusion of characters like Sakura and Alex could appeal to long-time fans, while new characters inspired by different cultures and fighting styles could attract fresh players. However, without official confirmation from Capcom, these remain speculative suggestions.
Overall, the community's enthusiasm for diverse and engaging characters highlights the potential for Street Fighter 6 to continue expanding its roster with exciting and unique fighters.
