Diego Estrada is an accomplished Mexican-American voice actor known for his work in the English dubs of popular anime series. His career is primarily associated with the prolific dubbing studios in Texas, particularly those connected to Funimation (now known as Crunchyroll), where he has become a recognizable voice for a wide range of characters.

Estrada's voice acting career gained momentum in the mid-2010s. He quickly established himself as a versatile talent, capable of delivering both intense, dramatic performances and lighthearted comedic timing. His background and fluency in Spanish have also allowed him to contribute to the industry in a unique capacity, occasionally working on Spanish-language dubs as well, though he is best known for his English-language roles.

His filmography includes a variety of significant roles that showcase his range. In the action-romance series Love of Kill, he voices Hou, a mysterious and skilled informant whose calm demeanor belies his dangerous connections. He demonstrated his comedic abilities in the yakuza comedy Back Street Girls: Gokudols, where he played Ryo Tachibana, one of three gangsters forced to undergo a physical transformation and become an idol group. Estrada also took on the role of the powerful and stoic Shirō Ashiya, the loyal former general to the Demon Lord, in the beloved fantasy-comedy The Devil Is a Part-Timer!!.

In more action-oriented roles, Estrada has lent his voice to Iwao Akatsuki in the revived adaptation of Spriggan, playing a determined operative of the ARCAM Corporation. He portrayed the complex and manipulative Kanade Uryū in the supernatural drama Platinum End, a character whose actions drive much of the series' conflict. He also voices the fierce and determined fighter Lihito in the popular martial arts tournament anime Kengan Ashura, a role that allows him to convey raw aggression and physicality.

Beyond the roles listed, Estrada has built a career through recurring collaborations with the same dubbing studios and directors, frequently appearing alongside a consistent ensemble of fellow voice actors in Texas. While he maintains a focus on his craft rather than a public persona, his body of work reflects a dedicated professional who has made a substantial contribution to bringing Japanese anime to English-speaking audiences. His ability to navigate between dramatic leads, comic relief, and villainous antagonists has solidified his place as a prominent figure in the modern era of anime dubbing.
