As a regular Brawl Stars player, I have watched the roster grow from a small set of scrappy fighters into a huge universe of personalities, but Sirius feels like a genuine event. He is the 100th brawler in Brawl Stars, and the developers clearly wanted his arrival to matter. Sirius is also the first-ever supervillain in the game, which instantly gives him a different flavor from the usual heroes, villains, and chaotic creatures. He fully joined Brawl Stars on March 5, 2026, and I grabbed him through Brawler Blast. As an Ultra Legendary brawler, he costs 5,500 Credits, the same price as Kaze, the first brawler of that rarity. That price tag made me pause, but after a few matches, I understood why he sits at the top of the rarity ladder.

Sirius is listed as a Controller, but I think that label undersells him. When I play him well, he does not just control space; he controls attention. His basic attack, Binary Starr, fires two projectiles with different purposes. One projectile deals area damage, and the other targets a single opponent. Every four hits, I collect a brawler shadow, a copy of my opponent. I can hold up to three shadows at once. That mechanic alone makes me feel like I am building an army during a match, and I love that slow-burn power curve.

His Super, Shadow Summon, sends those shadows onto the battlefield, where they attack my opponents. If I already have active shadows, using the Super again lets me command them, directing where they should go. That is the part that separates a good Sirius from a great one. Random shadows are annoying, but directed shadows are terrifying. His Hypercharge, Unlimited Power, makes shadows have more health and deal higher damage. When that activates, I feel like the match has tilted in my favor.

Ability	What it does	How I use it
Binary Starr	Fires two projectiles: one area, one single-target	Poke, charge shadows, and control lanes
Shadow Summon	Sends shadows out; with active shadows, commands them	Zone enemies and force them into bad positions
Unlimited Power	Hypercharge buffs shadow health and damage	Snowball after I have three shadows

After testing different loadouts, I believe the strongest build is Star Power 2, The Darkest Starr, combined with Gadget 2, Master of Shadows. The Darkest Starr gives me two shadows after the standard four hits, which doubles my tempo. Master of Shadows recalls the shadows to Sirius and recovers some health, which keeps them alive longer. Together, this build lets me create shadows sooner and make them battle longer. For me, it is the best choice for Sirius. The other options are Star Power 1, Dusk Runners, which increases shadow movement speed, and Gadget 1, A Starr is Born, which shoots a projectile and creates a shadow on hit. Those are fine, but they do not match the raw consistency of my preferred setup.

To play Sirius effectively, I try to accumulate all three shadows quickly, then overwhelm opponents with a massive attack. Sirius thrives in all Brawl Stars game modes because number advantage is very significant. In Gem Grab, my shadows can distract and pinch. In Knockout, they can scout and force early retreats. In Brawl Ball, they can create chaos around the goal. In Hot Zone, they can help me hold space. But Sirius is not easy. He is not as straightforward as Frank, for example. The effectiveness of shadows becomes real when I control them, not just let them wander randomly. During dynamic matches, that is a lot to track. I have lost fights because I summoned shadows and then forgot to direct them. When I remember to command them, I feel like a puppet master.

Sirius has good potential to hit the Brawl Stars esports scene, just as Kaze did with the versatility of her two forms. Professionals need time to weave him into their strategies, but I would not be surprised to see him picked or banned in coordinated play. Perhaps Brawl Cup 2026 will be the first opportunity to witness Sirius at a big event. That tournament runs from May 15 to May 17, 2026. With Pierce joining the game in late December, the game received 12 new characters in 2025, and Sirius is now the 100th brawler in 2026. The pace of releases is wild, but Sirius stands out because he adds a new fantasy: commanding copies of your enemies.

As an ordinary player, I think Sirius is a special release. He is complicated, expensive, and demanding, but he is also one of the most creative brawlers I have played in a long time. The Shadow Master might have given the development team a nudge, enough to make him overpowered. I am still learning his limits, and I am still losing matches when I mismanage my shadows. Yet every time I summon three shadows and command them across the map, I feel like I am playing a different game. If you are saving Credits or waiting for Brawler Blast, Sirius is worth the investment. Just remember: do not let the shadows wander. Control them, and they will control the match.
