Marvel Rivals Tetrameron Event begins with Season 10 as the new seasonal story event, placing Loki , The Chronicler at the centre of a task-based reward track. NetEase’s launch notes describe The Tetrameron as a story event where players assist Loki by completing tasks and earning rewards while Season 10: Butcher’s Blasphemy unfolds.
The important thing about the Marvel Rivals Tetrameron Event before launch is that NetEase has confirmed the event itself but has not published a complete text list of every task and reward. That means there is plenty we can say accurately about when it starts, who it focuses on and how it is structured, without inventing a costume, currency amount or final milestone that has not been named.
Marvel Rivals Tetrameron Event: What Is The Tetrameron?
The Marvel Rivals Tetrameron Event is Season 10’s main seasonal story event. Its official description asks players to assist Loki, The Chronicler, by completing tasks for rewards.
It sits directly alongside the new Butcher’s Blasphemy serial and the Season 10 story material for Gorr and Loki, so the event is part of the season narrative rather than a disconnected arcade challenge.
When Does The Tetrameron Start?
The Marvel Rivals Tetrameron Event launches with Season 10 on September 11, 2026. The game update begins at 09:00 UTC with around two hours of maintenance.
Because Marvel Rivals is inaccessible during that maintenance, players should expect to enter The Tetrameron once the Season 10 servers return.
How Does The Tetrameron Work?
NetEase says the Marvel Rivals Tetrameron Event revolves around completing tasks for Loki. That confirms a mission-style progression structure, but the patch notes stop short of publishing the entire objective list before launch.
There is no official basis yet for claiming a fixed number of stages, a precise daily reset structure or a specific final reward. Those details should come from the live event screen rather than guesswork.
What Rewards Can You Earn?
The official Marvel Rivals Tetrameron Event wording promises ‘abundant rewards’ but does not name the complete reward pool in the September 9 patch notes.
That matters for anyone looking for a day-one reward guide. If a supposed complete list names a final costume or exact Unit total before NetEase has shown it, it needs stronger evidence than the launch notes currently provide.
Is The Tetrameron Free?
Nothing in the Season 10 patch notes presents the Marvel Rivals Tetrameron Event as a paid Battle Pass or store purchase. It is listed as the season event, separate from The Godbomb Battle Pass and the new store bundles.
That separation is useful: The Tetrameron is the event activity, The Godbomb is the Battle Pass, and Gorr’s Divine Destroyer Bundle is paid store content. They all arrive around the same update but are not the same progression system.
Who Is Loki The Chronicler?
Loki , The Chronicler is the central character in the Marvel Rivals Tetrameron Event and also one of the highlighted Season 10 Battle Pass costumes.
Season 10’s story material focuses on Loki’s changing relationship with truth and Gorr’s campaign against the gods, which gives The Tetrameron a direct place in the wider Butcher’s Blasphemy narrative.
Does Gorr Appear in The Tetrameron?
Gorr is the headline new villain for Season 10, but the official Marvel Rivals Tetrameron Event description specifically tells players to assist Loki. The patch notes do not provide a complete event story synopsis or promise a specific Gorr encounter inside the event.
It is therefore safer to treat Gorr as central to the season story without pretending the live Tetrameron mission sequence has already been fully documented.
How Long Does The Tetrameron Last?
NetEase has not published a specific end date for the Marvel Rivals Tetrameron Event in the September 9 launch notes. The event begins with Season 10, but a precise closing time is not listed there.
That means players can safely plan to start on September 11, while anyone trying to leave the entire event until the final day should wait for the in-game event timer rather than assume it lasts until the end of the season.
What Else Launches With The Tetrameron?
The Marvel Rivals Tetrameron Event arrives alongside Gorr, The Godbomb Battle Pass, Scarlet Witch’s rework, the Season 4 Battle Pass rerun and new Season 10 Ranked and Twitch rewards.
The official Season 10 patch notes confirm the Marvel Rivals Tetrameron Event and describe its Loki-focused task structure without inventing unrevealed rewards.
