He comes to investigate what was happening. But then, after seeing too much of it, Ludo throws him into the medieval kingdom of Mewni and traps him with no way to escape. Now after what happened to him, along with Seymour, they attempt to try to return back to their home dimension and get vengeance on Ludo while assembling a team of warriors to help aid in their quest.

Now after what happened to him and Kyle they attempt to try to return back to their home dimension and get vengeance on Ludo while assembling a team of warriors to help aid in their quest.

Tiana O'Donnell: She is a dark, scary, terrifying demon who lives in the Afficited Forest.

However, since her childhood, unlike many others, she had been able to read and soon mastered her clan's lore and history, legal laws as well as healing and certain decree of magic (especially enchanting). The lord of the tribal confederacy was convinced by her skill and talents, therefore make her a bureaucrat of sorts. Contradict to her profession, however, her true dream is to see the whole world.

In Mewni, she accidently caused trouble with the guards and thus lost contact with her fellow travelers there. His personality is that he's not talkative and is often stand behind a crowd. She has trouble express her complicated ideas fluently and soundly, is described by many as sloppy and having her mind on the clouds. However, Sigrid is thoughtful, wise, objective thinking and rarely let emotion influence her decisions. Also, unlike what people think, repetitive and easy tasks bored her very quickly. She is ambitious and adventurous, it is just that...not adventurous in the style of holding the swords and go into danger. Even though being able to recite her clan's laws and history doesn't help much when being outside, it shows that Sigrid has very good memory. Healing, both by spells and by herbs, is another left-hand skill of her. Sigrid is also a part-time amateur magic users, making many magic items which are very useful, but most of these items come with a huge or stupid flaw that were cause by her sloppiness.

Gabriel Flynn: He is a 17 year old boy originally from South London, however he was accidentally transported to Mewni completely by chance when he was 11. While the Magical High Commission we're dealing with a monster incident in a back alley near Selhurst Park, Gabriel found himself coming back from a trip to the corner shop. While taking his usual shortcut to his home down that particular alley way, he stumbles upon the situation, unnoticed by all around him. In an attempt to send the monster back to its rightful dimension, Heckapoo opens a portal to Mewni to try and lure the monster back. Gabriel, naturally curios, steps into it. Still unseen. He stumbles into Mewni, scared and alone. After several hours of wandering through dark and murky forests, Gabriel comes across the Butterfly Kingdom and mainly the village below the great castle. He is taken in by a sympathetic family and raised for the next 3 years. Now know as the Mewman with a funny accent, Gabriel is bullied for being different to the other kids. Badly. At the age of 14, he had taken the last straw and leave at midnight in Winter. Never to be seen by his adopted family again. Left to his own devices, he learns basic combat and the street smarts necessary to survive in the magical dimension. His natural British quick-wit and sarcasm a handy tool still to this day. He is 17 years old standing at 6 feet exactly with light brown hair, styled into curtains. It is thick and medium length, reaching the tops of his ears. He has a stereotypical British accent (similar to Kevin from AnimatedJames' series 'C Students'). His fashion style consists of regular blue denim jeans, trainers and different checked shirts (usually neutral colours like black, grey and white. But he does have the odd purple and navy blue one as well). He always carries with him his trusty umbrella, which is plain black. He tends to use it for pure 'British style', in his own words, but it can double as weapon. Usually using the handle like a staff, but it does have an extendable blade hidden at the top of the umbrella. Although it is only used in the most serious of situations, other than that. It's for threatening. Also only in the most serious of situations and challenging fight (so not every time there's a battle), Gabriel dons a black Tribly hat with a single purple stripe running across the bottom of the top section of the hat. Gabriel Flynn is your typical Brit, smart, funny, quick witted and sarcastic (often to his own detriment). He is passionate for what he believes in can even become emotional at points. Although not the strongest, his tacticalness gives him the edge of most openings in combat, observing weaknesses and isolating them to his own advantage. However, when up against a well rounded opponent he faces his greatest challenges as his sheer tactical awareness and use of umbrella is not enough to defeat a smart, strong and agile opponent. His sarcasm is his greatest downfall, although funny at first, it often lands him and his party in hot water from him blurting out ironic observations at the wrong moment. It can also be used to frustrate opponents in fighting, allowing him to use their irrational anger against them, by beating them with calmness and agility. (I'll go see if it's possible to make him appear there or not). Character made by: spicy_meme_broke (from Discord).
