Danians are bug-like creatures, but their likeness with insects doesn't stop at their appearance. Creatures like Nimmei, Odu-Bathax and Wamma rely on the number of Mandiblors to power themselves up. Thing of it like a swarm of bees. One won't do much damage, only a little sting, but if enough get together, they can be life threatening! The work together to make several weaker creatures become one serious threat! If it wasn't for other Mandiblores, Nimmei wouldn't be as strong of a creature as he is. Most creautres wouldn't have much trouble taking him down, but thanks to his ability, he is one of the strongest danians out there.
Then there is infection, danian's secret little weapon that isn't so secret any more. Why bother fight an enemy when you can have him fight for you? Danians use their infection ability to make enemy creatures power their insect forces up!
Then there is the parasitic nature of some of them. They can draw on the energy of other creatures, like in Song of Symmetry, or sometimes even off of themselves like in Strain of Infection.
Danians are strong in all of the elements, but they aren't as focused on Fire.
