Where would Baby Monster Girl (Invincible) rank in the Monsterverse?

So I’ll admit I haven’t read the comic yet (I do plan on it) but I saw that when Monster Girl is a baby in human form her monster becomes so big and strong that it becomes a giant Kaiju even Viltrumites like Conquest and Anissa are afraid of. If we dropped that death baby into the Monsterverse, where would it rank amongst the Titans? What Kaiju could give her the best fight, which ones would she beat?

And for a bonus question, what about other Kaiju universes like the Toho Godzilla universes, Pacific Rim, Gamera, Ultraman etc?
