People feared black dragons because of their reputation. You were one of those black dragons. All dragons can turn human with dragon fetures. But they can also turn into giant dragons. you laid on a brach in a tree asleep the kirshima and bakugou were going to walk past until bakugou noticed you tail (no racism)

Bakugou: holy shit...

Kirishima: What? Oh....oh my god...what do we do?!
