OMG, you guys! The Penacony drama king himself, Sunday, might finally be joining our teams in Honkai: Star Rail! 🕊️✨ Ever since he got locked up after that wild finale, I've been on the edge of my seat wondering if we'd ever get to play as him. Well, hold onto your Stellar Jades because the leaks are spicy! Rumor has it he's coming in Version 2.7 as a 5-star character. Can you believe it? The main villain, playable! How wild is that? I can't wait to see how they weave his comeback into the story—will it be a redemption arc, or is he still scheming? 🤔

So, what's the tea on his kit? The leaks point to him being an Imaginary-type Harmony character. Yep, another support for our collection! But here's the kicker: he's not just any support. He's rumored to have a game-changing ability that could shake up the entire meta. Think about it—what if your favorite DPS could ult even faster? That's the dream, right?

Let's break down what we think we know:

• Path: The Harmony (Support extraordinaire!)

• Element: Imaginary

• Rarity: 5-star (Obviously!)

• Key Rumor: Can increase allies' Ultimate energy. Sound familiar? It's like a supercharged version of Tingyun's ultimate, but potentially for the whole team!

But wait, there's more! The most exciting leak is about a brand new "Overflow" mechanic. 🤯 What does that even mean? Well, imagine your characters generating more energy than their bar can hold. Instead of wasting it, this overflow energy could get funneled back to specific teammates! Is this on his Skill? His Ultimate? We don't know for sure yet, but the potential is insane.

Why is this "Overflow" mechanic such a BIG DEAL?

Let me paint a picture for you. Think of your favorite hypercarries who live and die by their Ultimates:

Character	Why They'd LOVE Sunday
Jingliu ❄️	Faster ults = more time in her enhanced state! More slashes!
Firefly 🔥	Her whole combo relies on that ult. Faster cycles = more damage!
Argenti ⚔️	Two-layered ult? He could charge the second layer in a flash!

This mechanic could literally bring forgotten DPS characters back into the spotlight. Have a unit you love but never use because their ult feels too slow? Sunday might be their new best friend!

Sunday vs. Robin: Sibling Support Showdown! 👯‍♂️

With both Sunday and Robin being Harmony siblings, will they compete or complement each other? Let's compare the rumors:

• Robin (Physical Harmony): Your go-to for raw ATK and CRIT DMG buffs. She also has that awesome team-wide Action Advance on her ult.

• Sunday (Imaginary Harmony - Rumored): Focused on Ultimate Energy regeneration and potentially that new Overflow mechanic.

Honestly? I think they'd be an unbeatable support duo. Picture this: Robin buffs your damage through the roof, while Sunday ensures your DPS is ulting every other turn. The synergy could be absolutely broken (in the best way possible).

Could Sunday also be a DPS? ⚡

Here's a plot twist! Leaks about his signature Light Cone suggest the wearer gets increased damage and energy regen after using skills. Sound familiar? It's giving Aventurine and Silver Wolf energy—characters who brilliantly blend support and damage roles. Could our angelic boy be a hybrid hypercarry in disguise? The possibility has me so excited!

Final Thoughts & The 2026 Meta

It's still early, and leaks can change (remember, this is all speculation for 2026!). But if Sunday arrives with this Overflow mechanic, he could fundamentally change how we build teams. The meta often shifts based on enemy toughness and character synergy. Sunday might not just enable the current top DPS; he could redefine who is a top DPS by fixing their energy problems.

Are you ready for the ultimate energy battery? Start saving those pulls, because the Harmony family reunion on our teams is about to get lit! 🔥 What team are you planning to put him in first?
