Immense Strength: (Well, PK is a half-dragon yk?)
Fire Breath: (Again, Pebble Knight is a half-dragon)
Indestructible:: PK's skin is impenetrable by any means
Sword Master: PK's a master of all sword & sword style
Combat Exp:: 582 years (PK's a half-dragon, so...)
[Swordication]:
PK has the innate ability to transform any pebble into a sword, which is done by giving them a soul in a process known as "Recognition", where PK breathes into a pebble to make them recognize that they're in fact, alive
The reason this works is because hylozoism's in fact, real, & since PK has fire breath due to being a half dragon, & fire's said to be "Life Essence", then.....
