There is always room for more and there will be plenty of new faces, as well as some familiar ones, coming to the Rift this year.
With some limited details surrounding future releases, we look at champions we know, suspect or hope will be added to the game in 2020.
Champions we know
'A whimsical new jungler'
This new jungler was subsequently revealed to be part of an upcoming summer festival within League of Legends.
The language used included blossom, dream and prancing which has led some to suspect the new jungler to 'fawn over' could well be inspired by deer or satyr.
While Soraka has a similar appearance to a faun, she is instead a celestial, while Kindred is another champion some have suggested could link to this new jungler.
There is a splash art from Legends of Runeterra titled 'Meadow Guardian' that seems to fit the descriptions being given so far, so could be of the same species.
'An edgy solo-lane melee carry'
While Aphelios is edgy and Sett is a melee brawler, both were already covered by other descriptions provided over the last few months in regards to new champions.
Early concepts for Sett do mean it is possible for these designs to be reused in future but it is unlikely to be for a champion in the near-future.
This description could link to the 'masked champion that refuses to die' below as they were mentioned at separate times, but it could also be yet another unknown figure. There are a few options below that might end up being this mysterious champion.
'A masked champion that refuses to die'
A few champions such as Kindred, Shen and Tryndamere have abilities that literally prevent death while items can prevent death or delay it like Guardian Angel and the Stopwatch.
However, this masked champion looks set to be defined by his refusal to die.
There is not a lot to go on with this description, but there is a possibility that this could ironically be the 'familiar face' coming to the Rift.
Legends of Runeterra introduced fans to a whole host of new figures from the League of Legends world. With card descriptions themselves being canon, we can assume the characters introduced and expanded on in the card game could be options for future additions to the main game.
With this in mind, Minah Swiftfoot is the first option. This Ionian is an opposite to newly-released Sett, using her feet rather than her fists to take down enemies.
As an Epic Card in LoR, there is potential for Minah Swiftfoot to be a future brawler and join many other martial artists and fighters already in the game.
With the popularity of Yasuo maintained heading into 2020, a new warrior could enter the fray for all of those samurai sword-wielding anime fan Yasuo mains to get some variety in their competitive LoL diets.
Yasuo's older half-
Overwatch has its own pair of warring brothers in the form of Genji and Hanzo so it would not be surprising to see League of Legends go down the same route.
Yet another Ionian, Ren Shadowblade is certainly edgy and could possibly be the solo-lane melee carry.
The splash art gives Ren shadowy blades like his namesake and it looks like being up-close-and-personal is the way he strikes.
Freljord's deck sees the likes of Scarthane Steffen and Tarkaz the Tribeless in Legends of Runeterra, but the main game's lore was what first introduced us to numerous members of the Winter's Claw.
Scarmother Vrynna leads members of the tribe during an encounter with Sylas in The Shackles of Belief.
In the same story, we meet Thorva, the Sister of Frost and the iceborn warrior Brokvar, both could also be contenders to be added into League of Legends following the addition of Freljord Sylas as a skin in reference to this story.
Shiraza the Blade
One of the Reckoners, a group of warriors that entertain the masses in fighting arenas across Noxus, Shiraza the Blade was also featured in Legends of Runeterra.
With multiple other Reckoners and pitfighters including Vessid and Kato the Arm throughout LoL history, it seems unlikely all of these figures would stay out of the brawl for too much longer.
Sett's unnamed pitfighter father is also a possibility, especially with the backstory suggesting his son's efforts in the pit were initially designed to try bring him back.
Only time will tell which champions are indeed added later this year.
