Description
Dekao Oyama is a supporting character in the anime series Rockman.EXE Beast+. He is recognizable by his imposing physical stature and his distinctive mohawk hairstyle, and his height is recorded as 152.9 centimeters. As a student, he is a classmate and close friend of the protagonist Netto Hikari, and he operates the powerful NetNavi GutsMan.EXE.

In terms of personality, Dekao often presents a gruff and irritable exterior, which can make him seem like a bully or a troublemaker at first glance. He tends to view Netto as his main rival, frequently seeking to prove his superiority in Net Battles and competing with him for the affection of their friend Meiru Sakurai. However, this rivalry is not born of genuine malice. Despite his tough appearance, Dekao has a notably timid side and can become easily frightened or begin to stutter in scary situations. At his core, he is a loyal and caring individual with a strong sense of friendship, and he proves to be a reliable ally when he is truly needed. He also has a deep affection for his younger brother, Chisao, showing a responsible and protective side to his character.

Throughout earlier series, Dekao's primary motivation was to defeat Netto and prove his strength as a Net Operator, though his operational skills never quite match his ambitions. This competitive drive leads him to seek out rigorous training, including a period on the island of Jawaii with former members of the criminal organization World Three. Over time, his focus shifts from being strictly a rival to pursuing his own path. He develops a strong passion for cooking and eventually becomes a curry chef, working at the Maha Ichiban restaurant. While he continues to hold a flame for Meiru and sees Netto as a romantic rival, Lan is often completely oblivious to the situation.

In the context of Rockman.EXE Beast+, Dekao appears as a member of the supporting cast. His role in this specific season continues to build on his established character as a friend and ally to Netto and the others, often providing muscle and support during their various conflicts. However, specific details regarding his unique storyline, dialogue, or direct involvement in the primary plot of Beast+ beyond his presence are not extensively detailed in available records. As such, his function is consistent with his role from the final parts of the preceding series Rockman.EXE Beast, where he is seen observing events from the sidelines.

For notable abilities, Dekao relies almost exclusively on brute force when Net Battling. His strategy is generally straightforward, relying on the sheer power of his Navi, GutsMan, to overwhelm opponents rather than employing complex tactics. Beyond battling, his most significant developed ability is his culinary skill, having been entrusted with the kitchen at a major restaurant by the time of the later series.
