* SugarWiki/AwesomeMusic: If there is one band whose entire career is more characterized by SugarWiki/AwesomeMusic than is Music/BlindGuardian's, it's almost incontestably Therion. Just [[AwesomeMusic/{{Therion}} check the page]].
* BrokenBase: There's a huge split of certain fans that prefer the earlier death metal sounds, and others that prefer the clean gothic style of later albums.
** Christofer Johnsson singing versus the various singers on their later albums has also been up for debate.
* GermansLoveDavidHasselhoff: While popular enough in their home country of Sweden, they've had much more commercial success in places like Germany, Poland and Hungary; ''Sitra Ahra'' even debuted in the top 5 of the Hungary album charts on release.
* {{Narm}}: Therion has its moments too.

* ReplacementScrappy: Christian Vidal. While he is an excellent guitarist in his own right, the general consensus is that he [[StuckInTheirShadow simply can't measure up]] to Kristian Niemann.
* SignatureSong: "To Mega Therion" is the main one; "Schwarzalbenheim", "Invocation of Naamah", "Blood of Kingu", and "Rise of Sodom and Gomorrah" get played live quite often as well.
