JLA: World Without Grown-Ups #1

Robin, Impulse, and Superboy burst forward atop an enormous JLA symbol, arms outstretched with unmistakable energy, while ghostly figures of the adult Justice League loom large in the blue-tinted background behind them — a striking visual that captures the title's generational tension perfectly. This 1998 DC two-parter puts the young heroes front and center in a story where the grown-ups are conspicuously out of the picture. Cover pencils by Humberto Ramos and Mike McKone, inked by Wayne Faucher and Mark McKenna, give the whole thing a kinetic, youthful charge that suits the premise beautifully.
