The 'Miku Miku Beam' is a viral internet phenomenon centered around the iconic Vocaloid, Hatsune Miku, performing a playful, magical-girl-style energy attack. While anime characters firing beams is a classic trope, this specific iteration gained massive traction on platforms like TikTok and YouTube through fan animations and VTuber recreations of the catchy audio. The meme typically features Miku striking a dynamic pose and shouting her signature catchphrase, followed by a colorful blast of energy. It is widely used to represent a sudden 'dose of cuteness,' a playful distraction, or an overwhelming wave of fan enthusiasm that 'attacks' or 'converts' the viewer in a lighthearted, humorous way.
