One thing that has been a consistant fear of failure. There are other fears too, but the most consistent one is failure.

87 Donatello has no stated or implied fears. But if he did have a fear it would possibly be that all his inventions would be a complete failure, or be used for the purposes of evil.

2003 Donatello: The episode titled "The Darkness Within" shows that Donnie's greatest fear is the demise of his family and loved ones. This can be interpritated as failing to prevent his family and loved ones from meeting their deaths. And later episodes shows that he also fears being a direct cause of said deaths. This also can be viewed as a fear of being left behind.

2012 Donatello has no acknowledge fears but there is at least a few implied or hinted fears. The most common one is 'Failing to fullfill the promises he has made to people who are counting on him.'

Other fears are a fear of being left behind...as in fearing his brothers will excell at Ninjutsu and advance in rank, while he will be left behind in the dust. As he states in Tales of the Turtle Lair, "It feels as no matter how hard I train, I just can't keep up with my brothers."

I believe there is a hinted fear that he doesn't truely belong. Donnie in someways sees himself as the odd duck of the family. And other moments where the other three treat him like he doesn't exist. This may be looked at even more in later seasons.
