Monster High

Spectra has a very forceful personality; she often makes snap judgments and leap to conclusions without supporting evidence, and when she's confronted with the facts she tends to dig in her heels. This makes for an excellent gossip columnist, but not a friend toi would want to share secrets with. In her diary it's hinted that she's constructed a mysterious, fanciful history for herself, and even began to believe it herself, but that the truth about her family is actually quite tragic (though it's never revealed). This may be why she's still a ghost; she hasn't "moved on" from whatever happened...
