I like ligers because they are such fascinating big cats. They are the offspring of male lions and female tigers. Ligers tend to be larger and more powerful than either of their parents and surprisingly quick for their size, bursting with hybrid energy and stamina. They are about the same size as Smilodon AKA the famous saber-toothed cat (minus the sabers). After watching this video of ligers, they are not the big killer cats you would expect. Instead, they are essentially large, lazy, and spoiled babies.
I am thinking of including ligers in my fantasy world and their origins would be based on a local fairy tale and children’s story. I will base this legend on a Greek myth about the Myrmidons. In the original legend, the first king of the Myrmidons prayed for Zeus to give him a strong and powerful people to rule over. Zeus granted his wish by turning every ant on the island into a human and the Myrmidons were born. Because they used to be ants, the Myrmidons were the original Ant-Men.
