Ok, this isn’t new or anything, but I want to get other peoples opinions on this. I believe that the Pokémon would win, but only if we’re following anime rules. Game rules, its probably the lions. The way I see it in simple terms, dialga freezes the lions in time and giratina can teleport them to the distortion world. If it’s game logic, the Pokémon would eventually run out of PP and could only use struggle which would barely do anything to the lions. But what’s your input?
