Vier gegen Z is a German children's television program shown on ARD and KI.KA in which four children are appointed as "Wächter" by their deceased aunt Hedda to prevent Zanrelot, the "Herrscher der Finsternis" from leaving the underworld and gaining control over Lübeck. As of September 2006, two seasons of 13 episodes each have been broadcast. The show's success has sparked the creation of a total of 6 novelized versions of the television episodes.
The main characters parents are cousins and it's mentioned that they met during some sort of family party. Also two of their kids are also in love with each other.
In the last episode of season 1, zanrelot kills a past version of himself and by this also his current self, you can argue if this is actual suicide, but I am going to say yes.
Since it's a kids show there is nothing shown, tho sex is referenced throughout the entire show (for example in one scene Sascha talks about a one night he had with Julia And in another one when Otti offers Larissa that she can stay the night at his place, she replies with "I don't know if I am ready for this")
In "Zanrelots Geheimnis" pinkas dresses up in typical mediaeval clothing and says "I look like Peter Pan after sex change surgery" but since he is not wearing a real dress I guess not really
A lot of people headcanon Z, Jona and Matreus as LGBT, however they are at most queer coded and since it is never explicitly stated, I am going to say no
There are multiple dead parents including: •The father of Leonie and Karo (his death is not shown on screen and it's not explained how he died) •Both of Franz's parents (his mother died because of the plague and his father is beheaded, both deaths are just mentioned) •both of Odalinde's parents are killed by Zanrelot(once again it's just mentioned) •Jonas mother( it's not explicitly stated how she died, it's mentioned that Z has something to do with it tho, also her death is just mentioned) •Jonas father(he freezes to death in a snowglobe, his death is shown on screen)
In the episode "Reise ins Nichts" Z and Matreus create gummy drops, that result in matreus being high, it's debatable if this really counts as "drug use" because it's a fantasy drug
