Heroes who are more likely to accidentally foil their own plots than the ones of villains they're fighting against, due to stupidity, bumbling, poor planning, cowardly behavior, weak strength or willpower, arrogance, and/or unwillingness on their part.

For obvious reasons, these heroes are likely not Successful, but in certain cases, they CAN still succeed in their goals, albeit they have the help of much more competent heroes, just with sheer luck or simply after taking much unnecessary and difficult detour in their path to their goals.

Pure of Heart heroes will NEVER fall under Incompetent as they are capable of performing wonderful heroic acts and causing immense advantages in a story which actually makes them very competent. But NPGs have to have a minor dose of incompetence, otherwise, they fall into Inconsistently Admirable or Heroic Benchmark

Even if, in very rare cases, some Pure of Heart heroes and NPGs are somewhat incompetent (e.g Tari) they should go under the Dimwits, Cowards and/or Weaklings categories instead.
