Rain Boy

Rain Boy made their Marvel debut in 2005's X-Men #171, brought to life by the creative team of Peter Milligan and Salvador Larroca, stepping into a Modern Age landscape rich with mutant storytelling. Over two decades of publication history — stretching all the way to 2026 — this character has woven through some of Marvel's most compelling X-corner titles, including New Mutants, Reign of X, and Trials of X. Along the way, Rain Boy has shared pages with fan-favorites like Karma, Rahne Sinclair, and Victor Borkowski, placing them squarely within the vibrant, emotionally charged world of younger mutant characters. With 18 catalog appearances spanning 21 years, Rain Boy is a quietly enduring presence in Marvel's mutant tapestry — the kind of discovery that rewards the dedicated reader digging deeper into the X-universe.
