'destroyed' is the definition.
The definition and answer can be both related to competing as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?

'a little fellow touring the kingdom' is the wordplay.
'a little fellow' becomes 'ned' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'touring' is an insertion indicator (touring can mean going round).
'the kingdom' becomes 'uk' (UK is an example).
'ned' placed around 'uk' is 'NUKED'.

'by' acts as a link.
