The sun is a solar mass that Makes up 99% of the mass of our entire solar system, bathes all objects in the solar system in deadly radiation and heat as well as give light to us, it's surface is so hot that the atoms that make it up have turned into plasma, can lash out at planets with a wave of charged particles that can destroy the power system, it can create antimatter, which when it collides with matter they vaporize each other into pure energy with 100% efficiency, the sun emits enough energy to equal a few billion nuclear bombs exploding every second and fuses more Hydrogen per day than the weight of all the planets asteroids, moons, comets and the Oort Cloud equaling to An in fathomable amount of energy and heat, on top of that The heat we experience today is over 170000 years old and still going strong, I think it's safe to assume the sun would win against anything inside our solar system, plus all it would really have to do to kill all those Lions is send out a burst of solar wind, or simply die
