I’ll say it plainly: Marvel Rivals players have been spoiled. The game arrived with a healthy content pipeline, and when the community pushed back against mid-season ranked resets, NetEase actually walked the plan back instead of digging in its heels. That kind of responsiveness spread through the player base like heat through a starship’s ventilation shaft—quickly, and without asking permission. Back when The Thing and Human Torch were about to complete the Fantastic Four lineup, the announced roster was nearly full, but the wishlist machine never stopped humming. Even now, in 2026, that early wishlist chatter still shapes how I think about the game’s future.
The character request that keeps resurfacing is not another mutant or armored genius. It’s Cosmo the Spacedog. Cosmo already charmed audiences in Guardians of the Galaxy Vol. 3, and the idea of controlling a psychic space dog in Marvel Rivals felt less like a joke and more like a missing puzzle piece. The case picked up steam on the Marvel Rivals subreddit, where a user named RedEyesGoldDragon made the pitch and the comments turned into a full brainstorming session.
Why Cosmo Would Fit 🐕
For me, the appeal is not just “add a dog.” Cosmo could slide into a support role with a psychic kit that works like a mental pressure valve. Instead of only healing, Cosmo might apply brief confusion, reveal enemies through walls, or toss out a telekinetic slow. That would give Jeff the Land Shark some serious competition in the adorable-but-annoying category. One commenter described Cosmo as “a psychic healer/attack,” which is exactly the kind of hybrid role that keeps matches from feeling like two trains ramming into each other on the same track.
Players also threw out ability ideas. My favorite was called “Puppy Dog Eyes.” The pitch: a 12-second cooldown that melts opponents’ hearts when they lock eyes with Cosmo, leaving them unable to act for 3 seconds purely from extreme adorability. It sounds silly, but in a game where chaos is already the default state, crowd control disguised as cuteness would be a delightfully weird tool.
Not everyone wanted Cosmo to be a full playable character, though. The pushback wasn’t about hating the dog—it was about emotional damage. One player said something that stuck with me: “Please don’t make me repeatedly kill a retriever dog.” That’s a real concern in a hero shooter where enemies get eliminated constantly. Making Cosmo an ult or a summon could give players the joy of seeing the good boy without turning every match into a guilt simulator.
A Quick Fan-Made Cosmo Kit
If I were sketching out a kit based on the community chatter, it might look like this:
| Slot | Idea | Why It Would Work |
|---|---|---|
| Primary fire | Telekinetic bark pulses | Short-range psychic damage that feels punchy but not cruel |
| Secondary | Mind Link heal | Locks onto an ally and restores health over time |
| Ability 1 | Zero-G Fetch | Pulls a nearby enemy or object slightly out of position |
| Ultimate | Puppy Dog Eyes | A short stun rooted in overwhelming cuteness |
That table is pure fan speculation, but it shows why Cosmo keeps coming up. The character is flexible enough to be a healer, a disruptor, or an emotional support dog—sometimes all three at once.

The wider Marvel Rivals community obsession is its own strange star. Around the time these Cosmo posts were making the rounds, players spotted an account with 2,749.9 hours of game time and 18,106 matches. That number is so large it feels less like a stat and more like a flashlight aimed straight into a black hole. Whether the account was shared, bugged, or just powered by an inhuman amount of momentum, it became a symbol of how deeply some players have fallen into this game. It was the kind of number that makes you whisper “go touch grass” and then immediately queue for one more match yourself.
That’s the thing about Marvel Rivals: the game has managed to build a community that treats every update like a holiday and every weird character pitch like a possible future. Cosmo the Spacedog may or may not ever join the roster, but the fact that players are this invested is a good sign. If the developers ever do add Cosmo, I’ll be first in line to main a psychic space dog—just as long as the enemy team is emotionally prepared to lose to puppy eyes.
