So many are quick to judge Type: Null and UB-01 for their "names". I wouldn't say that they are names per say.
Type: Null was just created to do a specific task and to rival mythological Pokémon, the creators didn't care about naming it so it is just called by its classification/project name. Mewtwo was technically not even given a real name, just Mew and two, probably its project name. Type: Null wasn't cloned from one specific Pokémon so they couldn't name it Absoltwo (or whatever you think it resembles :P ), it was synthesized from many Pokémon, a chimera, its creators obviously didn't care about naming it because it wasn't supposed to be treated like a normal Pokémon, it was made to serve a purpose, one we still don't know what it is. At least, that's my take on it :P
UB-01 is easier to explain, it is unknown, is it a Pokémon? Nobody knows. They are just anomalies in the Pokémon world and has no info about them. They can't name something that is unidentified, for now they are being classified as Ultra Beasts until more information surfaces.
I love Type: Null more and more every time I lay eyes on it, it's cool as heck and has an interesting story, even the name grows on me
Edit: Sorry for the double post :P
