Tobirama is both strong and badass, loved when he he made the cave (where they were summoned) start cracking by just lifting a finger, + yea, invented ftg, edo tensei, dan's reika nojutsu, shadow clone,gojo kibakufuda (since you can't use it without edo tensei) dude is a f*cking genius, well above minato, he insta understood sage oil was'nt nullified by tsb even without being a sage mode user while minato was there looking confused, fast to act, is a better sensor than minato, minato is just a copy of tobirama, and version 2 ftg is bullshit, because tobirama already knows how to mark a kunai and use it its just that minato named it and used it more efficiently
