Oryx wouldn't die instantly, and it wouldn't nesicarily kill Oryx, even if it is that powerful.

Yea it would...I just put all the math down in a post and when I went to check my calculations I lost the post...so here the laments term. Oryx evil/weak against light. (Source destiny) Spirit bomb = light, strong against evil (source dragonballz) Ever weakness/strength modifier on average is 1.5 so water to fire would have a critical ratio of 1.5 Seeing as how oryx has two handicaps to Goku, the critical damage he receives is stacked to x3. Gokus highest known power level is 1,000,000,000+ (Kid buu is really the highest known but Goku defeated kid buu therefore having a higher power level) Kid buu= 1,000,000,000 Oryx a pet golgoroth has a little over 10,000,000 hp and is the tankiest bullet sponge in destiny to Date besides Oryx. But let's go ahead and assume that Oryx has 10 times more health. That would put him at 100,000,000 hp. An unrealistic amount for any guardian to do without blights. See where this is going? Well let's go ahead and say that oryx has 100xs more HP than Golgy. Now we have a whopping 1,000,000,000 hp monster God. A number that no developer in their right mind would give to an endgame boss. So... Where does that leave Goku when armed with a power level that matches oryx full hp? Too far ahead....because Goku has a 3xs stacking bonus which would put him in the 3,???,???,??? Range. Easily Goku would be able to take on 3 super oryxs single handedly, then go back home to Chi Chi and a dinner table full of food.

Holy shit. I didn't think Spirit Bombs would have that much power, damn.
