Obito had Mokuton from 2 chapter ago, so what? Suddenly he can grow plants from his body parts instantly to spear through enemies? I can attribute that to emotional shonen power-up/breakdown.
But the Mangekyo Sharingan teleportation is something else. Overusage with no practice and just unlocking it as well.
Also in my original post I stated the random jump in power because Obito has 2 of the most powerful bloodline abilities in one chapter thanks to Rin's death.
Which reminds me Rin, screw you for dying and getting captured in the original Kakashi Gaiden. Naruto should blame you for causing Obito to go mad and ended up releasing Kyuubi, causing his parents death and a whole bunch of other junk.
