there were so many, plus, its just fun to see what you know, I'll start
lightfoots: a tribe of increbily agile raptors with more or less tribal beleifs.
cloudrunners: a rather peaceful group of terasaurs who seem to run as a primitive monarchy.
earthwalkers: a race of dino's from various species who lack the ability to fly, or for the most part swim. they follow a royal member, again like a primitive monarchy.
I love Cloud Runners. You know the one that Krystal flies on? I had a dream that it told me it's name was Kyte. I know the spelling because he gave me a bit of paper with his name on it XD
OK my turn:
Red Eye: A dangerous and carnivorous dinosaur tribe known for their reckless and intimidating behaviour.
Thorntails: A friendly dinosaur tribe that often give valuable information when not eating grass or ambling about.
Sharp Claw: A reviled group of pirates lead by the infamous General Scales.
grubtubs: a species of mobile fugi, favorite food of the earthwalker tribes.
bombfodads: a bouncy bunch of seemingly rodent species. these mystical and mysterious creatures are embedded with magical powers capable of bringing the fallen back to life
moon beasts: a groups of unknown origin from an unknown place. these creatures were thought to have come from a comet that struck dinosaur planet (and luckily they did no follow the same fate as the dinos here on earth). these creatures are only vulnerable on one purple diamond shaped opening on their backs and could possibly be a plant species due to the seeds they drop when killed.
bomb plants: plants capable of spontaneous energy release once put to a fire
galdon: a mantid like reptilian that has three main attack, a bite, an energy blast that only happened when his throat is exposed, and to eat the enemy. he walks on four legs and posses a pair of arms.
snow horn tribe (something like that): a tribe of mastodon like creatures who are very friendly and seemingly rebellious group. they will do favors at a price, such an example would be when fox rides a snow horn he must keep feeding the creature or he will no longer be able to ride it.
The Sharpclaws were actually created when a moon hit the planet (now Moon Mountain Pass). At least, that's what the Nintendo Player's Guide says... Sounds odd, but there you have it.
Also, are those annoying flying enemies called Sharpwings? I heard that somewhere...
I don't know, but they are very annoying, oh and here's one.
apariods: insect like creatures that have the ability to assimilate technology and people alike. upon assimilation they can alter technology to perform in ways never seen before. these creatures can absorb organic beings and the queen may manipulate their voices. it is unknown whether or not these creatures are organic or mechanical as both forms have been seen wandering around the planets.
I know, not adventures, but in assault they fought the apariods on dinosaur planet
