Titans #5 (Rebirth, 2017) – Wally’s Last Run!

Still reeling after reclaiming his pre-Flashpoint memories, Wally West realises the Speed Force is killing him each time he pushes past its new limits. When Linda Park is kidnapped by Kadabra, Wally redlines anyway—vibrating through Meta Solutions’ defences, flattening Mammoth, and yanking Linda out of a flaming deathtrap. The last-second save backfires: Wally’s heart can’t sync with the Speed Force and he’s violently yanked into it, vanishing in front of the Titans. The cliff-hanger tees up his “death” and leaves the team shattered going into issue #6.
