Gru has several, but an especially noteworthy one is when he breaks into Vector's Fortress in an attempt to get Margo, Edith and Agnes back from him. This involves jumping over and around a series of heat-seeking missiles and then punching a shark in the face. With an Offhand Backhand.
Just before that, Gru delivers this threat to Vector (via video):
Gru: Listen close, you little punk, when I get in there, you are in for a world of pain.
(Vector laughs it off, thinking that Gru is just blowing hot air... until Gru punches the camera hard enough to crack the lens).
The DEFINING CMoA for Gru has got to be his first real "dad moment", which involved blowing up a (fixed) amusement park game being run by a Jerk Ass. Said jerkass would not give Agnes a stuffed unicorn as a prize for hitting a small target, simply because it wasn't "knocked over." So Gru took a turn at the game and used his personal blaster on it. He knocked it over... and disintegrated it... and most of the game booth with it. Needless to say, Agnes got her unicorn.
The Minions, who have been portrayed as about ditzy and scatterbrained, managed to do something just awesome! Well, technically one Minion, but if he could do it, so could the others. They are capable to hacking in government records, to change Gru's personal records. Why is this awesome? Because it was during the moment when Gru was talking to Miss Hattie! The Minions are just AWESOME!
Vector may be a real Jerkass, but the way this guy kept Gru from getting inside his house was not only very hilarious, but very impressive.
Mr. Perkins managing to intimidate Gru of all people. Makes you wonder what he was like or would be like as a nasty super villain talking to their younger, and probably stronger henchman.
A real example: This film becoming the 9th highest grossing film of 2010. No? How about becoming the 24th highest grossing animated film of all-time with $543,113,985, half a billion? OR the 11th CGI film in lifetime gross, Either way, this film is Universal's most unforgettable film and Illumination's highest-reviewed film yet! Even way better, the film surprisingly got very good feedback.
Gru, Nefario, and the Minions building a working rocket - without the support of the bank.
The part where the girls jumped over to Gru, most notable was when Margo tried to jump over. It TRULY redefined Climax Jump.
