Locke is one of the strongest AP assassins introduced in League of Legends Season 26, capable of taking over games through explosive burst damage, excellent roaming, and deadly teamfight execution. While Locke is perfectly capable of carrying games on his own, pairing him with the right teammate can make his strengths even more impactful.

The best champions to duo with Locke are those that provide reliable crowd control, strong engage, map pressure, or enough damage to quickly follow up on his assassination attempts. Whether you’re playing with a Jungler who can repeatedly gank mid lane or a Support that excels at setting up picks, the right synergy can help Locke snowball games much faster.

In this guide, we’ll rank the 10 best champions to duo with Locke in League of Legends, explaining why each champion works so well with him and how you can use these combinations to dominate ranked games throughout Season 26.

#10: Udyr

Udyr is a strong duo partner for Locke thanks to his excellent early-game presence, fast jungle clear, and ability to pressure lanes from the opening minutes of the game. Since Locke excels at snowballing early leads, having an aggressive jungler like Udyr can make the laning phase much easier.

Udyr’s mobility allows him to reach mid lane quickly and repeatedly threaten ganks. Once he closes the gap with his crowd control, Locke can easily follow up with Ritual Nails (Q) and Ashen Pursuit (E) to secure kills. Even if the enemy escapes, forcing them to burn Flash gives Locke more opportunities to punish them later.

Beyond the laning phase, Udyr continues to complement Locke by controlling neutral objectives and invading the enemy jungle. His durability and frontline presence create space for Locke to dive into fights and eliminate priority targets without immediately being focused down.

If you’re looking for a reliable jungle duo that can help Locke snowball early and maintain pressure throughout the game, Udyr is an excellent choice in Season 26.

#9: Graves

Graves is an excellent duo partner for Locke thanks to his strong early-game damage, fast jungle clear, and ability to consistently pressure the map. Together, the two champions form a highly aggressive mid-jungle duo capable of creating early leads and snowballing games before the enemy team has time to scale.

During the laning phase, Graves can frequently invade the enemy jungle or pressure the mid lane with early ganks. His burst damage pairs perfectly with Locke’s assassination potential, making it easy to secure kills whenever Locke lands his abilities or forces the enemy to overextend.

Once the early game is over, Graves and Locke continue to work well together by controlling objectives, invading enemy territory, and catching isolated targets. Graves provides sustained damage while Locke quickly eliminates high-priority carries, giving the duo excellent skirmishing power around Dragon, Rift Herald, and Baron.

If you enjoy playing an aggressive mid-jungle combination that can dominate the map from the very beginning, Graves is one of the best champions to duo with Locke in League of Legends Season 26.

#8: Leona

Leona is one of the best support champions to duo with Locke thanks to her incredible crowd control and reliable engage. Since Locke excels at bursting down enemies who can’t escape, Leona’s ability to lock targets in place gives him the perfect opportunity to land his full combo and secure kills.

During the laning phase, Leona can roam from the bottom lane to help pressure mid, creating easy setup for Locke whenever the enemy is pushed up. Her chain of stuns and roots gives Locke plenty of time to connect Ritual Nails (Q), engage with Ashen Pursuit (E), and finish off opponents before they have a chance to react.

As the game progresses, the duo becomes even stronger in skirmishes and teamfights. Leona can initiate fights with confidence, forcing enemy carries to burn mobility spells or defensive cooldowns, while Locke follows up by diving into the backline and eliminating priority targets.

If you’re looking for a support that consistently creates kill opportunities and makes Locke’s assassination combos much easier to execute, Leona is one of the best duo partners available in League of Legends Season 26.

#7: Yasuo

Yasuo is a fantastic duo partner for Locke because both champions thrive in aggressive skirmishes and can quickly snowball games through coordinated plays. Their high damage output allows them to eliminate enemies before they have time to react, making them a dangerous mid-jungle or mid-support combination when paired with teammates who can provide crowd control.

During the early game, Yasuo’s mobility and sustained damage complement Locke’s burst-oriented playstyle. While Locke weakens enemies with Ritual Nails (Q) and looks for an opening to engage, Yasuo can quickly follow up to extend trades and secure kills.

The duo becomes even stronger during the mid game, where both champions excel at roaming and catching isolated targets. Locke can instantly burst priority carries, while Yasuo provides consistent DPS to finish off anyone who survives the initial combo. Their combined damage also makes skirmishes around Dragon, Rift Herald, and Baron extremely difficult for the enemy team to win.

If your team has reliable knock-ups to activate Last Breath (R), Yasuo and Locke become an even more threatening combination. Their ability to quickly eliminate high-value targets makes them one of the strongest offensive duos for climbing ranked in League of Legends Season 26.

#6: Amumu

Amumu is one of the best jungle champions to duo with Locke because of his reliable crowd control, strong teamfight engage, and excellent gank potential. Since Locke excels at bursting down immobilized targets, Amumu gives him the perfect setup to land his full combo and quickly secure kills.

During the laning phase, Amumu’s Bandage Toss (Q) creates easy gank opportunities in the mid lane. Once he lands his crowd control, Locke can immediately follow up with Ritual Nails (Q), Ashen Pursuit (E), and his burst combo before the enemy has a chance to escape. This combination makes it much easier for Locke to snowball an early lead.

The synergy becomes even stronger in the mid and late game. Amumu’s powerful teamfight initiation groups multiple enemies together, allowing Locke to dive into fights and maximize the impact of Purgatory (R). With enemies locked in place, Locke can safely eliminate priority targets while Amumu absorbs the incoming damage.

If you’re looking for a jungle duo that offers consistent engage, excellent gank setup, and game-changing teamfight synergy, Amumu is one of the strongest champions to pair with Locke in League of Legends Season 26.

#5: Pantheon

Pantheon is one of the strongest champions to duo with Locke thanks to his dominant early-game pressure, reliable crowd control, and global map presence. Together, they form an aggressive duo capable of snowballing games by constantly creating picks and winning skirmishes across the map.

The synergy becomes even stronger once Pantheon unlocks Grand Starfall (R). His global ultimate allows him to instantly join Locke’s roams, turning 2v2 and 3v3 fights into favorable numbers advantages.

Since Locke excels at bursting immobile enemies, Nautilus provides the perfect setup for him to land his full combo and secure quick kills.

During the early game, Nautilus can roam from the bottom lane to pressure mid or help secure objectives with his strong engage. His Dredge Line (Q) and passive root make it extremely difficult for enemies to escape once Locke commits with Ashen Pursuit (E), often forcing Summoner Spells or resulting in easy kills.

In the mid and late game, Nautilus continues to shine by initiating teamfights and disrupting the enemy backline. His Ultimate guarantees crowd control on high-priority targets, giving Locke a safe opportunity to dive in and eliminate enemy carries before they can react.

Her knock-up provides the perfect setup for Locke to land Ritual Nails (Q) and follow up with Ashen Pursuit (E), giving enemies very little opportunity to escape. Their combined burst damage is often enough to secure kills before opponents can react.
