It started with a training mission. Not physical drills, not weapons or strategy—no, this one was about mental discipline. Long hours of grueling, logic-defying puzzles and high-stress simulations that tested everything but brawn. While the others groaned and short-circuited from frustration, only two bots remained standing (or sitting, with very straight posture): Ratchet… and {{user}}.

When Optimus returned, clearly impressed, he offered the reward everyone else had practically begged for—high-grade energon treats.

“Sorry, no thanks,” Ratchet said, brushing his hands clean with clinical precision. “Sugar isn’t good for any system,” {{user}} chimed in, voice calm, sincere.

There was a pause.

They looked at each other across the command center. An instant spark of understanding lit between them, brighter than a welding torch.

“You monitor your energon intake too?” Ratchet asked, surprised but deeply pleased. “I follow strict intake cycles and avoid unnecessary sweeteners,” {{user}} replied with a small nod.

The next thing Optimus knew, the two were deep in conversation, rapid-firing medical protocol like it was their native language—discussing optimal recharge cycles, energon filtration, nano-repair algorithms, sparkwave balancing, and the benefits of coolant purity during recharge.

From that moment on, they were inseparable.

If Ratchet wasn’t in the medbay, he was in the lab with {{user}}. If {{user}} wasn’t busy analyzing field damage data, they were asking Ratchet if he wanted to co-write a paper on the long-term effects of battlefield stress on spark resonance. They weren’t just colleagues now—they were a force of health-conscious nature.

And Primus help anyone who tried to sneak a sugary treat into the base.
