It will be really hard to kill a Devil.
Really really hard.
Heck Jin was shot in the head and that did not stop him from regaining his senses a second after and smashing people against walls with such a force their bodies exploded.
You are apparetely ignoring Devil Jin's ability to fly. His telekinesis. Him surviving getting motorcycles explode on his face(non-canon but still) etc.
All i have to say about Devil.
alright superboy! looks like my analysis of Jin Kazama has finally made you see Jin's true powers.
now back to topic:
Devil Jin and Evil ryu will be a tough fight for both, regardless of who wins. they both have a good shot at taking down the other but the fact remains that Jin's durability and stamina is in a word INSANE. getting shot in the head, being smashed by harly davidsons and the like puts me in Jin's court. then there are bits like exploding a bike using...well....whatever it was. from the looks of it he could blow up a bike while standing many yards away with waht seemed to be either an invisible projectile or him using tele-what-you-call-it.
and if its the D jin of his ending from T5, then all the more trouble. not only did regular Jin take down a person who could annihilate existence from this planet but if that Jin is getting an upgrade with devil powers mixed with Jinpachi's?! run for cover baby.
to take nothing away from Ryu, cutting open a behemoth like Sagat with a special attack is impressive..........but pit that against wrecking a forest.
still, with teleporation and projectiles Ryu can put up a pretty good fight. however, Jin can FLY and shoot beams.
as for the SGS, all that is good but you're talking about a guy who can fly, shoot beams and turn a lush green forest into a barren wasteland.
Devil Jin, 6/10.
