Talk with the Kages AU Headcanon
Gaara the Walking Fortress
During the Kage council with the former Kages present as the elder advisers asked where Onoki is and Mei mentioned he probably out there destroying buildings.
Imagine if this is a common thing. Like Onoki just randomly visits the other villages (because he has nothing better to do) and accidentally or intentionally destroys buildings and made all the Kage's alert because of it. But because of his age they are lenient even though he was a very terrifying Kage with a terrifying jutsus at his disposal.
Like,
"Dammit! Onoki caused havoc at a downtown construction site and accidentally blew up the foundation!" Naruto groaned.
"At least the building wasn’t finished yet—that would have been far more costly," Darui sighed, recalling the time Onoki had obliterated a newly constructed building. The aftermath had buried him in a mountain of paperwork, not to mention enduring a scolding from the Daimyo.
"We’re just lucky that the building he ‘accidentally’ destroyed was already condemned, with no one living in it," Chojuro remarked with a weary sigh.
"Kurotsuchi groaned. 'Are you kidding me? I live with the guy! Even before he retired, he was blowing up buildings left and right. Do you know how many times we had to rebuild the Tsuchikage's office? It was absolutely insane!'
The four Kages turned to Gaara, anticipating similar tales of destruction, but the redhead merely blinked at them in confusion.
"What?" Gaara asked, his expression blank.
"What do you mean, 'what'?" Kurotsuchi pressed. "Don’t you have any stories about my grandfather and his destructive tendencies?"
"What destructive tendencies?"
"What do you mean by that? My grandfather visited your village more times than I can count and... wait." Kurotsuchi paused, realization dawning.
Every time Onoki caused destruction, Iwa inevitably had to deal with the consequences—paying reparations to other villages for damages. Yet, she couldn't recall ever compensating Suna.
She turned toward the Kazekage, who was casually sipping his tea, completely unbothered.
"Did Suna ever suffer any damages?" she asked, suspicion creeping into her voice.
That got everyone's attention.
"Not that I'm aware of," Gaara replied, unfazed.
"What? How is that possible?" Darui burst out in disbelief.
Kurotsuchi pointed an accusatory finger at Gaara. "I knew it! You're the favorite!"
Naruto scoffed. "Favorite? Am I not the favorite?"
Kurotsuchi shot him a look. "What makes you think you're the favorite?!"
The Kage's don't know that Onoki did have accidents in Suna. It's just that, Gaara was always able to stop it before any damages can happen. He wasn't called the walking fortress for nothing. And Gaara, being Gaara, didn't think it was a big deal.
