If anybody was wondering about my other plans, I have some more original characters that I feel fairly confident with making movesets for. They are made-up and I did not take the ideas from anywhere else, except Blossomus is based off a Ricochet Infinity power-up called Blossom.
Alica Vassin Plan
Known by the nickname of Flame Kitty, Alica Vassin is no ordinary cat. With the ability to throw fireballs and unleash waves of flame, she is a worthy opponent both from range and in melee fighting, and can score KOs even with her projectiles. However you cannot use one half of her powers without the other. You won't get away with spamming fireballs, and you won't get away with spamming smash attacks. She has limited fire power, meaning after throwing about 15 fireballs, she'll have to wait some time before being able to use other fire-based moves. But combine all of them and you have yourself a very powerful foe. Flame Waves develop power and size over time, like R.O.B's lazer.
Akullotsoa Plan
I figured that Ice Wolf was a terrible name so I decided to find a foreign version of it and edit it to make a better nickname. While Alica Vassin's has fire as an outer layer; Akullotsoa has ice inside him, allowing him to breath it out and generate it from the tips of his fingers. He also holds a dagger which he uses in attacking as much as his claws, and he holds it in his right hand despite being left handed. He actually has more ranged moves than Alica Vassin, however his game is slightly more focused on his melee side rather than his projectiles. And like Alica, he has limited frost power, meaning that if he uses to much frost breath and throws too many ice spheres, he will have to rely on his claws and dagger.
Blossomus Plan
The idea of this moveset is to create a character that is completely ranged. It's melee attacks are mostly terrible, but he doesn't really have many since a lot of his standard attacks are projectiles anyway. The character itself is basically just Ricochet Infinity's Blossom power-up in Smash Bros., but of course you guys probably don't know this game so I'll explain the details in the actual moveset. With the ability to combo using his projectiles, Blossomus is quite hard to beat...
Except that it is so light that Ike's fully charged Side Smash will probably KO it at 0%. Your best bet is to use ranged moves against him, which Alica Vassin and Akullotsoa might be able to effectively pull off.
