Isabelle

Isabelle is the primordial host of the show Assets with Liabilities. She is a yellow shih tzu from the franchise Animal Crossing.

Who she is
She is a yellow shih Tzu dog from Animal Crossing. She can be nice for all the time, but then can be mad if you trigger her enough. Her TTS voice is Hazel Desktop, pitch +3.

Her niece Vadim and her brother Digby are both in the show, with the former in the Shenanigans and the latter in Cheer's C**ts.

From a financial perspective she has more money (emeralds) than Matt the show's executive producer himself because she literally took all Tom Nook's money from Nook Inc. and claimed that she owned the kingdom, even though Matt is the true prime minister, or owner, of the kingdom.

In Assets with Liabilities
From season I, Isabelle is a passive-aggressive dog who immediately applies Matt's challenges such as the Collect the Birch from the Oak Forest challenge without further planning, which could go wrong, like the House Building Contest, which caused a modified coronavirus pandemic in the AwL Mansion area due to the Screwed Blocks causing extreme coal emissions causing a modified pneumonia in the Death PACT 2 and C**ts.

In Tieuth's Animated Discourse on Minecraft and Its Buzzy Bees and Bugs
Isabelle constantly annoys Tieuth and his work on his own village, but does save his village from the raids that constantly happen all the time.

Trivia

 * Even though Vadim is her niece, Isabelle treats her as if Vadim's her proper daughter - which she wasn't, because Vadim's true mum is Elizabeth.
 * She would always sometimes give her duties mistakenly to Tom Nook because of how he acted like was one of the hosts - which Matt agrees all along, but Four doesn't.
 * Her being the host is a reference to Pocket Camp, wherein it seemed like she manages everything the player does to their camp, much like Tom Nook to the player in mainstream Animal Crossing games such as Wild World and New Horizons.
