#in this reading the nose lizard becomes OBVIOUSLY a Treecko

would anyone like to hear about my feelings regarding Boba Fett's character arc and Cubone/Marowak's evolution

well I'll let some Pokédex entries (via Bulbapedia) do the talking (obviously you need to substitute "father" for "mother" in Boba's case) (and I am, of course, being selective with my quotations because there are other parts of the Pokédex entries that don't fit with this interpretation at all, but that's okay because this is not about real life and no real person will be harmed by my rascality)

Pokémon Red and Blue: "Because it never removes its skull helmet, no one has ever seen this Pokémon's real face."

This is the earliest version of Boba Fett known to fans, mysterious and badass.

Pokémon Silver: "It always wears the skull of its dead mother, so no one has any idea what its hidden face looks like."

Once we know what happened to Jango and the symbolism of his helmet, this heartbreaking view of Boba emerges.

Pokémon Moon: The skull it wears on its head is that of its dead mother. According to some, it will evolve when it comes to terms with the pain of her death.

A little hope is suggested, that Boba may not remain always locked in the same state of trauma and grief.

Pokémon Shield: This Pokémon wears the skull of its deceased mother. Sometimes Cubone's dreams make it cry, but each tear Cubone sheds makes it stronger.

Excuse me while I believe that the fluid in Boba's bacta tank is somewhat diluted by invisible tears shed as he lies dreaming.

But then we get to Marowak!

Pokémon Ruby and Sapphire: Marowak is the evolved form of a Cubone that has overcome its sadness at the loss of its mother and grown tough. This Pokémon's tempered and hardened spirit is not easily broken.

This is the Boba that I feel emerged in The Mandalorian.

Pokémon Sun: The bones it possesses were once its mother's. Its mother's regrets have become like a vengeful spirit protecting this Pokémon.

Pokémon Moon: Its custom is to mourn its lost companions. Mounds of dirt by the side of the road mark the graves of the Marowak.

These entries refer to the Alolan form of Marowak, the one with a Polynesian design influence, which seems apt for a character played by a Polynesian actor who's been bringing elements of his culture into the role. Although Mandalorians don't believe in such things, I personally love the thought of some remnant of Jango's spirit within his armour - which at any rate provides real and practical protection to his son. While I detested the fridging of the Tuskens in episode 3 of The Book of Boba Fett, the Moon description tracks.

Referring to the standard Kanto Marowak again:

Pokémon Sword: This Pokémon overcame its sorrow to evolve a sturdy new body. Marowak faces its opponents bravely, using a bone as a weapon.

In this case, rather than the connection being to Jango, I see the bone aligning with the gaffi stick Boba carries. And his body sure is sturdy.

And this is why, if we are to imagine a Star Wars Pokémon AU, I would have little bereaved Boba finding a wandering baby Cubone in the arena on Geonosis, recognising it as a kindred spirit, and bringing it with him so they can grow up and ultimately evolve together.
