A full Bel'Veth skin gallery, plus the practical point: some skins change the silhouette enough to matter in a fight.
Before the cosmetics: Bel'Veth is a fighter at 150 attack range whose job is to trade repeatedly, survive the return damage, and win the third exchange rather than the first.

Bel'Veth has 4 skins, excluding chromas. The art below is the in-client splash.
Skins change no numbers. They are not therefore free of consequence — a skin that alters the silhouette or recolours an ability changes how quickly an opponent reads what you just cast.
That cuts both ways, and it is the honest reason some players keep the base skin on champions they take seriously.
Bel'Veth gains permanent attack speed stacks after taking down large minions and monsters and champions. She also gains temporary bonus attack speed after using an ability.
Bel'Veth dashes in a chosen direction and damages all enemies she passes through.
Bel'Veth slams her tail to the ground, damaging, knocking up, and slowing her enemies.
Bel'Veth roots herself in place, channeling a storm of slashes around her that targets the lowest-health enemy and grants her lifesteal and damage reduction.
Bel'Veth consumes Void coral remnants, transforming into her true form and increasing her max health, attack range, and attack speed. Consuming the Void coral remnants of a Void epic monster will grant her the power to summon Void remora.
A nightmarish empress created from the raw material of an entire devoured city, Bel'Veth is the end of Runeterra itself... and the beginning of a monstrous reality of her own design. Driven by epochs of repurposed history, knowledge, and memories from the world above, she voraciously feeds an ever-expanding need for new experiences and emotions, consuming all that crosses her path. Yet her wants could never be sated by only one world as she turns her hungry eyes toward the Void's old masters...
Skins are tied to the account, not to you. Anything bought on a smurf stays on the smurf — worth knowing before spending real money on one.
