These ideas even decent?

1. The Jawcerasaurs AKA The Comivians:
They are a formerly unknown race of snake like kaiju with large and strong jaws. They have grass-like hairs on their bodies, allowing them to camouflage easily on land. They camouflage by digging not very deep holes into the land using their mouths and sleep on them, waiting for prey to step on their back. Their main prey are cows and they change hair color depending on the season and location. The Queen and King Jawcerasauruses have arms that allow them to unleash devastating blow, They reproduce sexually through the use of their tail which has an organ for only breeding named the Progeneous Gland.
2. The Viridians:
They are an intelligent race of aliens with advanced technologies living on planet P79-86K41N or as they call it “Planet Corvano” They look like traditional aliens from early pop culture, but don’t let their look deceive you as they can be peaceful to aggressive in a matter of seconds. They are commanded by a president who is elected through a democratic election, much like humans. Their very advanced tech allows them to travel through space, galaxies and dimensions, and they have an ongoing 23 year war with another alien race named “The Wexans” who have started their war when they nuked one of Planet Corvano’s main cities with a Mutator Bomb by fooling The Viridians with a peace treaty, now the Viridians have a hard time of trusting other species due to it.
3. The Crawlasaufagus AKA The Exodians
They are recently discovered race of small spider like kaiju that move using their eight legs much like a spider. They also have claws that they use to inject a poisonous anesthesia like toxin to immobilize and poison their prey. Their body stands high much like a human and they reproduce by making eggs. Their poison helps in adding nutrients to their parasitic eggs, and they also have kings that make the eggs, the eggs can either be made asexually and parasitically. The parasitically making of eggs is faster and makes stronger hatchlings than the asexual way. But it needs a living thing to put inside the egg to absorb it’s proteins and nutrients, The Exodian kings are different to the normal Exodians due to them having sharper claws which has a more poisonous toxin. But the anesthetic composition in the poison is gone. They hide underground in hives and they focus on increasing their numbers, waiting for the perfect time to strike the Comivians since they are their rivals.
