Flashman is one of the stronger EXE villains from the anime, but he’s still no match for Omega Shenron. Omega Shenron is the final villain of Dragon Ball GT and he can end solar systems in the blink of an eye. This poses a major problem for Flashman since the thunder navi doesn’t have enough speed to dodge such a fate. Unfortunately, this means that his fate is sealed. Omega Shenron wins.
