Master Yi is very weak early, and Riven interrupts his Alpha Strike (Q) engage with a Ki Burst (W) stun, then bursts him down with Broken Wings (Q) combos before he scales.

Twitch is squishy, so Riven closes the gap with Broken Wings (Q), stuns with Ki Burst (W), and instantly melts him with combo burst.

Shyvana is weak in fights before her Dragon's Descent (R) transform, so Riven wins early skirmishes and invades with her Valor (E) shield and combos.

Before level 5 Evelynn lacks her Demon Shade (P) stealth and has weak damage, so Riven sticks to her early and bursts her down.

Before transforming, Kayn is weak in jungle fights, so Riven overpowers him in early skirmishes with combos and delays his Darkin Scythe (P) form progress.

Warwick sustains through extended fights with his Eternal Hunger (P) lifesteal, and his Infinite Duress (R) suppression locks Riven down, nullifying her Broken Wings (Q) dash escapes.

Olaf's Ragnarok (R) makes him immune to all CC, so Riven's Ki Burst (W) stun is useless, and he chases her down for the kill with Undertow (Q) slow while ulting.

Jax's Counter Strike (E) dodges Riven's autos and combo and stuns her, and his Grandmaster-at-Arms (R) armor and magic resist bonus lets him win extended fights.

When Riven engages, Darius pulls her in with Apprehend (E), stacks five Hemorrhage (P) bleeds, and executes with Noxian Guillotine (R), winning the extended fight.

Xin Zhao is the strongest early duelist, using his Three Talon Strike (Q) third hit and Audacious Charge (E) knock-up to interrupt Riven's combo and out-damage her in sustained fights.
