Unlike many of the monsters in the school, Blobert is undoubtedly the kindest and the sweetest. In fact, he is described as being the only classmate who is the least manipulative and murderous.

Blobert is known to be adored throughout the school, as even Vera enjoys his company. This shows that Blobert has a very positive influence on others. He believes in friendship and love, and is not indifferent to those who are being harassed, as such he is always willing to help out.

He seems to have a fondness for oddly specific greeting cards.
