Plot hole: During the presentation of Bloom Innovative's pizza printer, the villain who pulls the strings of the whole operation (and controls Bloom) is in the audience. Since Bloom at the end of the movie is not depicted as a sophisticated AI but just a holographic projection, it appears impossible that he could do his stage performance and interact (verbally at least) with principal and audience.

Plot hole: Bloom Innovative is depicted as an incredibly famous cutting-edge tech company with a massive social network presence. It is unforeseeable that its charismatic owner and public face would have been for years a hologram whose likeness is modeled after "the most famous male model in Japan" (let's forget the fact that it's pretty unlikely that'd be a white dude), not exactly a secluded country with no attention to media and tech. Later when they talk with the real villain, Velma in fact refers to him as "an obscure model", which would make much more sense plot-wise (but then Daphne couldn't have recognized him at first glance).
