First example, Burnats Magnis.
The name Rumblenaught is a play with what happens when they have a boxing or wrestling match in a large stadium. The rumble part is from minor seismic activity that would happen from those in the stadium or largely packed areas with spectators. The naught part of their name is derived from the expression tuff nut and naught by definition means nothing since when examined after fighting and taking heavy blows no major injuries were found and only soreness and small bruises were reported.
They’re wrestling and boxing addicts. Large arguments, debates, and sometimes courts will be disputed over wrestling. If authorized the court match will be broadcasted.
The majority of Rumblenaughts are friendly and aren’t aggressive unless needed to. Those off the planet work as care givers or help those with disabilities. They have a large sense of community and have strong bond with those in their community.
Those who are more aggressive work as security, police/government agents, bodyguards, or join sports leagues. Rumblenaughts that work as security or bodyguards are highly sought after off the planet. A low effort from a 200 lbs, male, can have 675 pounds of force.(enough to breaks rocks)
They’re figuring out how to turn their seismic into electricity. They have already figured out how to turn their kinetic energy from training equipment into electricity. (It took awhile since they kept breaking the ones for their smaller arms)
They had genetic mutations during evolution causing most of them to become half mammalian half reptilian. It’s rare to see one completely reptilian or mammalian Rumblenaughts because of how much genetic mutation effects what amount of mammalian and reptilian genes they get. This is also is believed to have caused them to develop their extra pair of arms, they ended up turning it into an advantage in evolution. Another thing genetic mutation probably effected is genetic makeup, which is why they wild patterns and colors in their genetic makeup. Horns and small (and slightly retractable) spikes seem to have also snuck their way into their genetics.
Their second pair of arms are retractable and can come out of their backs. Their thumbs aren’t upright when they do this since they’re blades for their extra arms won’t allow that movement and motion. This is a disadvantage that they have when it comes down to it. A group of Rumblenaughts is called a ‘punch out’ They’re very open about gender identities and have hardly any gender differences, so most of them have gender neutral appearance. Heights fluctuates from 4'5 to 10'0 feet tall. 8'0 to 10'0 feet tall Rumblenaughts are the rarest heights. Spikes on a mostly mammalian Rumblenaught isn’t too uncommon. When quadruped their extra arms can be used for hold objects or will tucked in close to the body since they’re too short to touch the ground when walking. They can only use their extra arms when low to the ground since the second pair is up to the length of the first pair’s wrist. Leaving the second pair to dangle is dangerous and when crouching they can move fast since despite being shorter the second pair are stronger than the first pair.
That is what I have on them now and geez do I feel tired since I went out before writing the last few paragraphs.
