"Giant dragons can lay many eggs at a time, and although the hatching rate isn't very high, it's not uncommon to see several hatchlings from the same clutch all at once. That's why it's not rare to find siblings among giant dragons."
"These two Storm Dragons are Twin Storm Dragons, which actually hatched from the same egg."
"This is a very rare occurrence, and only this kind qualifies as Twin Dragons. Moreover, these giant dragons share a connected strength, and when the two fight together, their combined power can even surpass that of three or four individuals."
"Plus, these are mutated among the giant dragons, Storm Dragons, whose strength is naturally stronger than that of ordinary Blue Dragons."
