What does Satan cannot do that his children can do?

 The devil is always depicted mostly like this on earthly drawings

Do you think I am bluffing? No! I will prove to you from the verses of the Bible that this is true.

What are these things?

1) Satan cannot produce more wicked than him because he is the most wicked creature on earth but his children can produce more wicked than them.

Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves. (Matthew 23:15)

2) Satan sometimes stop to his evil doings 

And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord? (Acts 13:10)

but his children cannot do it and always continue before they sleep.

For they sleep not, except they have done mischief; and their sleep is taken away, unless they cause some to fall. (Proverbs 4:16)

3) Satan when exchanging ideas about religion stops when he feels that he cannot refute it.

And saith unto him, If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone. 

Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God. 

Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; (Matthew 4:6-8)

But his children on earth when debating them online do not stop exchanging ideas but instead repeating to you what arguments they already said even they know they cannot refute your arguments which lambasted their arguments.
