Some examples:
Julan's Lightning energy manifests as an enhancement to his speed, or turn himself into electricity to phase through conductive surfaces like metal
Quarrel's Earth magic allows her to manipulate the elemental energy of nearby rocks and dirt and mold them into whatever she wants

A fair chunk of my characters are capable of using magic through awakening their bodies elemental energy, it flows through their body similar to blood, the element they wield (Elementus) is determined at birth and can manifest in many different ways

the little rhymes describing what the magic can do are very cute,
Interesting stuff

That’s so cooooooooool!

They look so cool!

I... How...

I'm not ready for another completely new Smash game hype cycle especially in this day and age so just give Ultimate a little extra something and let Sakurai work on other things
