I have been following along with Truegreen7's series on Youtube where he and 3 other Fakemon artists get together to design a new pokemon based on the same prompt.
This Prompt was: Pretty, Protector, Protagonist

I started my prompt with the word "Protagonist", what animal and type would I want to see be a Protagonist? Well as evident by my love of Charizard and Salazzle I really like Hot Lizards so I would go for a Fire type Lizard! They are meant to be Feminine but I don't just want to copy Salazzle's look so I decided to go with a different body type to emphasize her strength, if Salazzle is a Glass Cannon of Special attack then this pokemon would be a Tank that can take a hit and give it back.

I decided to base mine off of the Marine Iguana, native to the Galapagos islands, they spend most of their time basking on hot rocky beaches to build up heat and energy to then go diving in the cold pacific ocean and graze on sea plants so Fire/Water type seemed perfect. They prefer being warm on land but they have adapted to a semi aquatic lifestyle. Another fun fact about Marine Iguanas that is relevant to this is that when they feed on sea plants they also end up swallowing some sea water and have to get rid of the salt somehow so they projectile sneeze the salt out their nose which is why their faces often look white and have salt crystals built up on their heads. I imagine this pokemon has a signature move where it fires hot salty steam out of it's big round snout that has a damage over time effect like Salt Cure.

Marine Iguanas are not what people often consider traditionally beautiful looking, Famous naturalist Charles Darwin called them:
"Hideous looking creature, of a dirty black colour, stupid, and sluggish" and then spent time picking them up from the beach and throwing them in the ocean to watch them swim back...this obviously is now very illegal. Thank you for your contributions to Natural Science Darwin, you also married your first cousin!

Personally I think they are very cool looking like something reminiscent of prehistoric times, while usually a black volcanic color sometimes Marine Iguanas bear a mix of Red and Teal which looks majestic. I figured the pre-evolution should look small, cute, and like something you would want to protect but has the potential to be strong. Mariguna is a fun loving child who loves to play on the beach. When they go swimming they make a bubble jet from the heat vents on their hands and feet to propel them through the water. Mariguna sometimes get picked on by bigger pokemon so they stick around their much larger evolution for protection.

Then Mariguna becomes Ambroyroar, a Big Sunbaking Beach Babe with scales that make it look like she is wearing a Bikini, and has muscles like a powerlifter, not a traditional feminine aesthetic but very beautiful nonetheless. They spend most of their time laying on the beach and up on rocky cliffs by the sea basking in the sun and building up heat. If anybody messes with their Mariguna then they are ready to move and fight at any moment using the heat Vents on their hands and feet to inflict burns on enemies.
