Chimera is a Person related to Greek mythology. Offspring of Typhon and Echidna, the mother of beasts, and is the sister of Cerberus and Ortro.
This monster breathes fire and is made up of parts of different animals. Generally it is depicted with the body and head of a lion and with a goat's head placed on the back and with a snake as a tail. Other myths describe it as a three-headed animal with a dragon as its third head.
He made his first appearance in 1992's Shin Megami Tensei. In the Persona series he appeared with 3's Persona 2006.
Originally it was part of the Arcanum Carro which has become Force in Persona 5 Royal.
This Persona can be found in a Palace after the original part of the game, which we avoid mentioning due to spoilers. Let's assume anyone reading this article has already reached that point.
He excels in Strength and the rest of the stats are quite high, don't underestimate his offensive power at all.
However, it has a not very high Resistance for the point of the game where you will encounter it, so a wind attack will be enough to knock it down and then via Relay!
Weak to Wind and Cursed, it can block Ice and absorb Fire so be careful when you run into it.
