Gru was just a non-canon side character in the first two Minions movies.
even though this post is a joke, this is how the majority of the minion fanbase probably thinks. in fact, i bet half of em don't even know who gru is, they only care about the yellow jellybean stuffstains.
honestly, the only thing that saves the movie in general is the fact that gru shows up at the end with his freeze ray
