not like he could hit goku with that. instant transmission constantly around the universe gathering energy. and GG whoever that is.
That's like saying Goku would know what attack was coming before he even did it.
It was never shown Goku to do such things, nor would it be in Goku's character to do so. Goku NEVER uses his spirit bomb at the beginning of a match. He ALWAYS does a warm up, but against someone like Z, it would be very bad for Goku.
The only way I see what you said to work is if Goku is blodlusted AND has full knowledge, but it wouldn't even matter since an attack like that wouldn't even phase Z.
