Which Godzilla enemy is your favorite and why?

I have a soft spot for space godzilla

My favorite Godzilla enemy is King Ghidorah! Why? Because he’s a flipping three-headed 500 foot tall dragon from space!!!

Thank you for your replies!

Mecha Godzilla. I felt sorry for it since people created and manipulated it. Too bad humanity wasn't just destroyed once and for all at that point. Godzilla Actual would have made a good partner!

My favorite Godzilla adversary is a tough call.  I can say my *LEAST* favorites are Biollante and Megaguirus.

Pretty much all of the Ghidorahs except for Mecha-Ghidorah. Monster X/Kaiser Ghidorah and Monsterverse King Ghidorah are my favorite Godzilla enemy.

The Ghidorahs are like the Joker to Godzilla's Batman, the Lex Luthor to Godzilla's Superman. Also I love dragons

Gigan has always been my favorite because of how awesome he looks (especially in 2004) and how he was the most brutal Godzilla villain.

Does Mothra count? If not, I also love Gigan, one of my favorite over-all kaiju.

It is pretty hard for me to choose other than Godzilla. Since this is about Gojira's enemies I'm might choose two which are

Ghidorah- since he has given Godzilla a hard time in almost every appearance plus his bio-electical gravity beams, and all his roars, and his overall design he looks pretty sick tbh, his defense is great and offense. He is such a great kaiju

Destroyah- has been a huge match for Godzilla that has been created with some of the particles from the oxygen destroyer, oh and he was pretty much O.P in Godzilla unleashed for the Wii which was a character I would often choose when not Godzilla

If not Gojira I would choose these two
