Badly create alien initially and so on (2,6)
I believe the answer is:
et cetera
'and so on' is the definition.
(I've seen this before)
'badly create alien initially' is the wordplay.
'badly' is an anagram indicator.
'alien' becomes 'et' (extra terrestrial).
'initially' is a charade indicator (letters next to each other).
'create' with letters rearranged gives 'cetera'.
'cetera' after 'et' is 'ET CETERA'.
(Other definitions for et cetera that I've seen before include "Etc" , "something similar" , "Drive out, expel" , "That can reduce length of sentence" , "Including other similar items" .)
