Jellian J. Jellswell XIII

Jellian J. Jellswell XIII, more commonly known as Jellswell, is the thirteenth and current Jellswell leader. Jellswell is the primary antagonist and final boss of Mando-Lynn. Jellswell is an industrialist Jellid who is the current CEO of JELLSWELL Industries Inc., and plans to tear down Mando and Lynn's tree house for land and destroy all music in the world, replacing it with his own after Mando and Lynn play loud music despite him asking them to stop. He is also the de-facto leader of the Fiscal Four.

Jellswell has two siblings, Jellzibelle and Jorts, and comes from a long line of historically significant Jellid magnates. He is a graduate of C.O.P.I.U.S. and has a complete monopoly many industries, including the soft drink industry.

He is a member of The Fellowship of the Scyphozoa, a secret society for only Scyphozoan Jellids, or "true Jellids." He is also a direct competitor with Janzworth.

Appearance
Jellswell is a deep purple Jelild with six tentacles for feet, and two for arms. He has large yellow bloodshot eyes, and dark purple eyebrows. Jellswell has dark purple bags under his eyes. Jellswell has twelve teeth, and a periwinkle tongue. He wears a light blue-ribboned teal top hat with seaweed stuck on the sides, a teal tailcoat and yellow cravat, and a white undershirt. He wears a long blue cape that reaches to the floor. He has a gold pocket square and carries a golden pocket watch with him at all times. He also has a black cane with a spherical golden top and bottom, with his name engraved into the bottom.

Business
Jellswell is incredibly stingy, obsessive, avaricious, and a ruthlessly efficient factotum. He also suffers from severe mood swings, and Chelonaphobia, which is genetic. This narcissism is further fueled by his posh nature, business/social success, causing him to strongly dislike any music that he doesn't feel is good. However, Jellswell is known to be highly intelligent and crafty, having amassed a large net worth and several degrees in various fields.

In Public
However, he appears "family-friendly" by providing many goods and services for anyone, as well as being a charismatic speaker and television personality, likely to avoid suspicion of corruption. He also claims every evil thing he does isn't entirely evil, and he does it "for the good of the people," and he could be "much, much worse" if he tried.

In Private
Jellswell is also musically inclined, as he enjoys playing the cello. He can be insecure about his plans around his family, who he looks up to. He has a dark, dry sense of humor that is often twisted, such as suggesting he'd "skin (Mando) alive," and "turn him into a red-panda-min."

Jellhannes' spoiling of Jellzibelle led to targeted animosity towards both him and Jellzibelle as well as the development of his severe stinginess, as well as harassment by other student's at C.O.P.I.U.S. who claimed his father's business practices "ruined their lives." He is vengeful, going after Mando and Lynn for seemingly petty reasons, as well as mistreating his siblings. Despite this, he still fought for validation from his father and family, who looks down upon his plans. This is not to say that Jellswell is an insecure person, it is to say that he is insecure about his family, as he has support systems through the Fiscal Four and Debbie.

If you were to inspect Jellswell's desk before the final battle with him, there are a series of writings that are interpreted to be poetry, presumably about another character.

Development
Jellswell originally started as an alien from Callipso. The head and pot like body changed into a plant named "Morris Rose," a play on words with "Morris" a male name, "rose," a flower, and "morose," a state of sadness. The vines that came out of his pot eventually turned into the tentacles that became Jellswell's. Jellswell originally was going to only have a last name, as a form of title. He was then given the name "Jellhannes," then "Seabastian," (after Johann Sebastian Bach). Eventually, after the inclusion of Jellswell ancestors, the creator wanted to have a "J-name that was related with influence," so Julius was chosen, after Julius Caesar. The name felt too "old", so "Julian" was chosen, which was later changed to "Jellian" to fit the Jellid theme.
 * The first Jellid-based design for Jellswell was originally going to wear a fishbowl helmet in order to avoid being dried out, as well as having thick black stripes on its then four tentacles. It was eventually scrapped due to the fishbowl helmet bearing similarity to a character in another game.

Jellswell also was originally Jellswell the III, but was changed with the introduction of his long ancestry. He became Jellswell XIII, as thirteen is seen as an unlucky or evil number. The inclusion of suffixes comes from figures such as John D. Rockefeller and Cornelius Vanderbilt, whose descendents are known to carry the same name for several generations.

Trivia

 * Jellswell's affinity for space is a joke based on the Aurelia aurita jellyfish species, more commonly known as the moon jelly.
 * Jellswell feasts on smaller jellyfish species. This is possibly based off of the Drymonema larsoni species, which are known to eat moon jellies.
 * He celebrates the day he got his first dollar as a holiday.
 * Jellswell is skilled at martial arts.
 * Jellswell intentionally polluting the waters around him and selling it as an aprodesiac is a reference to how in real life, pollution improves breeding conditions for jellyfish.
 * He is a patron of the arts, housing his favorite artist.
