His cold, calculating nature makes him both sinister and the exact type of mastermind you'd expect for the top spot on this smartest anime characters list.

L serves as Light's arch-nemesis in Death Note. Known only as "L" or "Ryuzaki," he is a mysterious international detective prodigy and one of the smartest anime characters. L leads the investigation into the "Kira" serial murders. Despite eccentric behavior, L's intellectual capabilities prove on par with or greater than Light's.

He makes deductions nobody else imagines through seeming intuitions bordering on the supernatural. Like Light, L has exceptional knowledge of mathematics, science, languages, psychology, and other subjects. He can analyze minimal data to uncover information people aim to hide.

L stays a few steps ahead of the Japanese police force and even figures out that supernatural forces give Kira killing power. In the battle of wits between L and Light, L deduces Light’s identity as Kira before his untimely death prevents him from definitively proving it.

As a teenager in early Dragon Ball hunting dragon balls, Bulma already shows herself as an engineering prodigy on par with full research institutes. She quickly grasps alien technologies and makes significant improvements to inventions like the scouter device.

Decades later, in Dragon Ball Super, a middle-aged Bulma continues to play a pivotal role through her scientific genius by creating new gadgets and methods to help her friends face increasingly potent threats. It makes her one of the smartest anime characters.
