i think only generation 1 dragon slayer who can't ride transportation. well in harc oracion ceis cobra feel nothing when he ride the nirvana. hmm... still a mistery.. （￣へ￣）
all of them couldn't but u're right..i never noticed that before orz & cubellious is no longer a flying snake & is not with him now ╥﹏╥
i think all of dragon slayer will become sick in transportation when they become full fledged dragon slayer..or when they already accomplish dragon force...thats what i'm thinking...so cobra must be can use dragon force now
or state magic power that strong enough to use dragon force
