Shame the Naruto character above you by...

[BlacLord™]

By giving any reason for Iruka beating them. I'll start with...

Rock Lee.

 

[Punk Hazard]

He goes 6th Gate and unties his bandages to blitz Iruka and land the Lotus. The loose bandages get tangled in his legs during take off and he crashes into the ground at the hypersonic speed, completely shattering his bones and tearing his muscles to shreds as he passes out.

Might Gai.

 

[SUPERDEADLYKING]

[Dantee]

Might Gai tries to avenge Lee's death but slips on an ice cube and breaks his neck.

Madara

 

[Punk Hazard]

Madara

Iruka stands before Madara with a kunai in hand. Madara activates his 3 Tomoe and Iruka starts shaking in utter fear. Madara steps forward, towering over Iruka, releasing chakra causing the ground around them to crack and break. He switches to Mangekyo and glares into Iruka's eyes to land a powerful Genjutsu. At the same time, Iruka holds up his arm in fear, the kunai across his face. Madara's eyes are reflected in the kunai, causing Madara to induce the Genjutsu into himself. Iruka then slits the immobile trapped Madara's throat.

Kakashi

 

[Illuminater]

Kakashi engages in taijutsu with Iruka and eventually uses his raikiri, it fatally misses his heart and iruka slips a paper bomb under his sandel killing kakashi.

For simplicity's sake, Onoki should be the next choice.

Hagoromo flys full speed at Iruka. Iruka sidesteps to pick up a penny while Hagoromo gets a face full of the bujii bomb

Kiba

 

[ChicagoJhawk]

Hagaromo calls out for all 9 tailed beasts to appear before him. All of them go around in a circle as they charge up biju bombs to attack at Iruka. But being the smart teacher, Iruka ducks and the bijuu bombs hit all the tailed beasts instead and hagoromo has not choice but to commit sepoku as he was embarrassed by the conniving Iruka once again.

But what about tsunade doe

Naruto

 

[Obito the supreme jin]

Iruka takes a look at Naruto. Naruto not yet made his full resolve to attack his sensei decides to hold back and stop Iruka from attacking with TNJ. Iruka in digust with how much he was underestimating him used substitution jutsu to escape the vicinity only to leave behind some delixious cup ramen.
