@Seekquaze1 : Well, Gaia isn't destroyed like Kronos, she's just been forced back to sleep. Honestly, if she woke up, she probably would've been much worse than Tartarus and the demigods would've been toast. They defeated Gaia before she could wreck havoc although I would have loved it if she was owned in a much better manner than Piper's charmspeak.

As for the Giants, although they were more powerful than the Titans,  they apparently lacked the brains to carry out a full scale war unlike Kronos.

All immortals and the Gods are quirky and Zeus is no exception. If Zeus wasn't an idiot, PJO wouldn't exist in the first place.
