I agree with you, akash94:
Nothing else but the most relevant official assertions legible on
should be considered:
'Tintin is neither a surname nor a name (...) nor a first name'
(page 1/8) and a sudden acceleration 'gives Tintin the distinctive quiff with which he is synonymous
' (page 7/8) ...
If Tintin's two syllables are really synonymous
of a kind of 'tilted M-shaped' quiff, then one of his 'many avatars' could be the two French syllables 'penche M', and be part of a kind of very unusual ...rebus, imho... (please see the 'rebus-like writing' thread).
Finding empirically the remnant of the syllables fit 'to tell a story in the story' should then just be a matter of intense and prolonged reflection -not to mention 'thought transmission'.
These syllables would then help identify in the corpus the various sequences of the special and strangely drawn 'avatars'
which are capable to 'write' a rebus-like 'story in the story'...
Thus Tintin is much more than a name or a nickname: he belongs to a totally unique world, the world of 'avatars' or word-images able 'to stand for something else'... Case solved, imho...
