If a Lion and Tiger got into a fight then the Tiger would be the one who probably killed the Lion.
Tigers are usually much stronger than Lions so the Tiger is the one likely to win in the fight against the two.
Although they rarely do fight each other than when they come up against each other.
But still the Lion will usually just walk away or run away from the Tiger if it feels threatened.
But then again if they did fight either one could win the fight but the Lion is likely gonna be killed by the Tiger in the fight or at least severely injured.
Tigers are much more powerful than Lions.
