Winx Club
Season 4
Marion is first mentioned rather vaguely in the beginning of Issue 97 by Bloom after she returns to Gardenia from Domino's royal palace.
Stella tries to ask Bloom how things went as she unpacks wishing to know every little detail of her visit, which prompts Bloom to ask if she would like her to start off with how she tripped over the red carpet or how she completely embarrassed herself in front of a crowd of major dignitaries by forgetting her speech. She then sinks down into her bed, claiming to be a catastrophe of a princess as she ended up doing the one thing she did not want to: disappoint her birth parents, and so Stella tries to bring her friend's spirits back up by assuring her that Oritel and Marion would still be proud of her no matter what she did. She even offers to give Bloom advice on how to behave like a princess should in all occasions until the pair are interrupted when Roxy enters the room to see if Bloom came back from her trip.
Halfway into the issue, Marion makes her debut after Neruman's ambush on the Winx upon their arrival into the Dark Dimension. She appears very concerned for Bloom alongside Oritel when Bloom suddenly wakes up to find herself mysteriously back in her room at the Domino Royal Palace.
As she tries to make sense of everything, Marion and Oritel explain to Bloom that she had already defeated Neruman but was the only one of the Winx to escape the Dark Dimension successfully, as its portal closed just behind her and trapped the others within it. The Fortress of Light templars were also able to rescue Bloom, bringing her back to Domino, but the rest of the Winx continued to remain trapped in the Dark Dimension with no other way out.
Having heard enough, Bloom springs to her feet with the intent of returning to the Dark Dimension's portal to save her friends, but Marion and Oritel do not wish to lose their daughter a second time. Eventually, after Oritel snaps at Bloom, Marion chimes in, insisting that Bloom's friends are lost forever now and that the Winx Club no longer exists.
Hearing all of this helps Bloom realize that the Marion and Oritel that stand before her are nothing more than imposters, as neither of them would say such horrible things, nor would they ever fear doing the right thing even if it came at a high cost. The two imposters then charge at Bloom, taking hold of her arms to prevent her from escaping. As Bloom struggles to break free, the two imposters reveal their true identities to be that of Neruman's shadows, and Bloom is able to beat them back with the help of her Believix energy and Flora's words.
Marion does not appear again until Issue 100 when, after being plunged into her own memories, Bloom finds herself back in front of her home in Gardenia, only to be greeted by Marion as Oritel argues with Mike and Vanessa over which set of parents Bloom cares for the most. As Mike and Vanessa rush over to Bloom to confirm their thoughts of how she cares for them more, Marion warns for Bloom not to listen to them as they do not seem to be acting normally. This causes Bloom to make a decision on whether she should embrace her foster parents to reassure them or rebuke them for thinking that she ever stopped loving them.
If Bloom chooses to embrace her foster parents and reassure them that she will always love them as much as her birth parents, Mike and Vanessa reveal themselves to be a pair of shadow monsters. Marion will then rush to Bloom's aid with Oritel as she struggles to transform in vain. As Bloom makes a dash for the door, Marion hastily explains that the shadow monsters temporarily canceled out her powers and urges for Bloom to save herself as they begin to multiply.
If Bloom chooses to rebuke her foster parents for thinking that she would ever stop loving them, then Marion will stand by Bloom with Oritel to praise her for standing her ground and tell her that they are one big family. That is when Mike and Vanessa reveal themselves to be shadow monsters and multiply at a rapid pace, prompting Bloom to put up a magic shield around her and her birth parents. As she struggles to keep the shield up, everything fades into sudden blackness and when Bloom can see again, she finds that her birth parents are gone and that she had somehow ended up at the Eraklyon Royal Palace.
Season 6
Marion finally makes her physical debut in An Unforgettable Party alongside Oritel, Daphne and Thoren when they arrive at the Solarian Royal Palace to celebrate the anniversary of Radius' ascent to the throne.
When chaos later erupts and Celsius' plan has been uncovered, Marion can be seen again hiding behind Oritel as he tries to fend of the mutant insects. Bloom hears her shriek and promptly comes to their aid by protecting them within her Red Dragon Orb. Unfortunately, this distracts Bloom long enough for a hypnotized Sky to attack her from behind.
Marion can be seen again at the very end of the issue dancing with her husband now that Celsius had been apprehended and his mutant insects had been properly dealt with. </tabber>
