If you're looking for something specific, the slides are named their concepts, so look at those. Otherwise, just scroll through. Thank you! If you can't find your answer, comment below your question and I'll try to help! Like I said, if any characters are made, I'll make a studio for them. Anyone will be able to add their characters. If you just wanna start small, I suggest changing colors of costumes, adjusting some damages, changing jump and speed stats, and/or adding some effects to attacks. Combining all these things is basically the goal, and you don't need to rush straight for the goal. But if you think you're capable of doing it all at once, I think it's achievable even with limited experience.
Smash Bros. is created by Nintendo and Sora, Ltd. Credit to Masahiro Sakurai and anyone associated. Most of this was made right after I made Pikachu, pre-Character 3. That's why almost none of it mentions that project, other than the end.
