yet he don't use them , maybe coz extreme chakra drain ? or zetsu was covering his body, he stated he momentarily _now_ have both senju and uchiha dna and that's why he should maybe be able to do stuff never seen before.. by that alone i'm not sure they are obito's abilities so you cant be sure either
Okay lets play along with the "Obito simply warps Itachi and its game over" argument.
So lets say Obito is about to warp Itachi. It has been proven to take about 2-3 seconds to fully warp someone, Danzous 2 body guards for example.
It takes less then a thousandth of a second for Itachi to activate susanoo.
Considering Obito needs to be tangible, near itachi, and 2-3 seconds to warp him, Itachi can activate susanoo within a blink of an eye, with the totsuka blade stabbing through Obitos body.
yeah and bigger the obstacle he need to warp longer he needs full big susano'o take's forever and OBITO NEED TO BE SOLID WHEN ABSORBING STUFF finally valid counter, he just cant "warp him instantly"
