Sylas can be said to be one of the champions with the most distinctive and versatile abilities in League of Legends, with the power to steal enemy ultimates. This has turned him into the champion with the most in-game interactions in the game and a potential candidate to become the owner of an Ultimate skin.

Recently, a League of Legends player on Reddit presented a very interesting concept for Sylas’ Ultimate skin, where he would have the ability to transform his appearance by stealing the ultimate of enemy champions. Upon stealing an opponent’s ultimate, Sylas would morph into a character that reflects the characteristics of the land from which that champion originates.
Specifically, he could transform into up to 14 distinct forms, corresponding to 13 famous regions in Runeterra and one special case for champions of unknown origin:

Bilgewater: The hallmark of this area is the “promised land” for pirates and the tradition of worshiping Nagakaborous. When Sylas steals the ultimate of a Bilgewater champion, he will don a pirate outfit, while his iron chains become tentacles.
Freljord: Sylas already has a Freljord-themed skin, so his Ultimate skin may be slightly altered, with the chains replaced by a frozen fur cloak.

Shurima: Sylas would wear a skin similar to Ryze’s Desert Guardian, and the chains would transform into sand.

Void: Sylas transforms into a semi-Void creature, with the chains becoming tentacles similar to Vel’Koz.

Ionia: The sacred land of natural magic would turn Sylas into a champion with a “flower wolf” outfit, and instead of whipping chains at enemies, he would whip bushes with magic.

Demacia: Sylas wears a magic-resistant armor and a crown, while his chains always emit a radiant energy glow.

Noxus: Similar to Demacia, Sylas will wear the signature armor of Noxus, with bloodstained chains symbolizing the brutality of this land.

Targon: Sylas transforms into a celestial being, with radiant chains.

Shadow Isles: Sylas becomes an ethereal entity like mist, and his chains resemble Thresh’s, made of deadly bone joints.

Ixtal: The homeland of elemental queen Qiyana, Sylas’ skin would resemble a native, with his chains formed by the three elemental states of earth, water, and plants.

Piltover: (idea suggested by a gamer) Sylas uses iron chains carved from crystal stone – sharing the same origin as Jayce’s hammer, and wears a noble outfit similar to Caitlyn’s.

Zaun: (idea suggested by a gamer) Sylas wears a gas mask, and around him are characteristic green chemical tubes.

Bandle City: (idea suggested by a gamer) This is also the most interesting idea, Sylas would shrink if he steals the ultimate of a Yordle champion, however, his chains would not change size, causing him to awkwardly drag his weapon whenever he moves.

In addition to the major regions in Runeterra, when Sylas steals the ultimate of unidentified entities like Evelynn, Nocturne, etc., he would transform into an undefined ghostly form.
This idea has immediately received much positive feedback from the gaming community; however, one unfortunate thing is that the guy seems to be too focused on the locations and forgot about the most beloved name in League of Legends: the race of the family-less – the… Darkin.
If additional Darkin champions were included, this would definitely be a rather interesting skin concept that Riot could consider for Sylas, of course, on the condition that they also buff him a bit to give this copying specialist a chance to “rise again” on the Summoner’s Rift.
