This could be like a magic, or your own custom ability, essentially I’m talking about like your own super powerful ability that cannot be used repeatedly because it’s either really energy consuming or it has some kind of cool-down.
Anyways here’s mine as an example:
sandals ultimate ability: MAGNUM OPUS
The user wields a massive magical pencil to rapidly barrage the opponent with the eraser side, before finishing off by drawing the ultimate life-form that fires a laser of total erasure at the target. Dealing massive damage and usually resulting in an OHKO
For me, my ultimate ability would be called, “ NO, MY PING!” The user basically creates multiple big explosions with explosion magic causing the servers ping to skyrocket so fast it freezes the game.
This is an all out spam of every single offensive spell from mutiple directions. Almost every magic is used and it converges on the opponent in a storm of colour and variety. Ends with a massive beam of mono-polychromatism magic, a magic which combines the unaligned arcane magic with every other type, including opposites and equinoxes (it itself is an equinox).
Very, very draining though and requires extreme knowledge and skill in magic.
Sounds kinda crazy, but I did have an idea for a story where the main character would eventually create and use this, but only once.
In terms of Smash Bros, it would appear more like a representation of its true capability.
The target is rapidly barraged with rays/projectiles/fists/constructs from every side, each construct being of a different element (smoke, lightning, fire, ice, poison, explosion, speed, time, dragon, memes, etc.) The target is then faced with a giant burning rocky fist imbued with every single element before being either uppercut into space or smashed into the ground, generating a massive elemental nuclear explosion.
