Mythical Lion

This Minecraft mob would be in a new end biome called the Chorus Fields, and would be a boss that would be created by placing 4 Netherite Blocks in a T-Formation, 1 Ender Dragon Head on top of the middle block, and 2 End stone blocks on either side.

It would have 500 Heath on JE and BE, and would have 3 attacks:

1) Floor Slam

He would slam the floor with his sharp paws, and destroy some of the blocks, as well as knock backing you and sending you flying up, then falling.

2) Paw Claw

The mob would slam his claw into you, dealing 8 Hearts of damage without armor, and also giving you blindness for 10 seconds.

3) Enragement

When the boss has 250 HP left, it becomes enraged, grows more, and sucks up some of the landscape, armoring it more. The attacks also become more powerful.
