The only giant dragon capable of rampaging without being subdued in Chen Yu's Necromantic Space, with such an imposing size, is naturally Xiao Lan, the mount of Jounouchi Hiromi.
Xiao Lan's original size wasn't as large as it is now, nor was it shrouded in storms—these changes were all brought about by its fusion with the Storm Divine Core.
Enhancements in size were expected; each stage of growth for the Giant Dragon Clan brought physical transformations. Adult giant dragons typically reached over thirty meters in length, Legendary Dragons could exceed fifty meters, and for a being like Xiao Lan, which had the rare chance to fuse with a Divine Rank to become an Ancient Dragon, breaking past one hundred meters was far from extraordinary.
Some giant dragons who lived long enough to grow into Primordial Ancient Dragons even surpassed three hundred meters in length.
