Quote from Syphilis
Tobi was funny; Obito is pretty lame. He doesn't say anything unexpected and is weaker than Madara...
Quote from Jun Tenkawa
Obito with the mask = silent, cool, mysterious antagonist
Obito without mask = ANGRY ANGRY UCHIHA. REVENGE!!!! REVENGE!!!! RAWR.
I don't dislike Obito but I liked his Tobi persona much more than how he is now.
