Mirrors are for scrubs. You straw man, he ain't stronger then! You speak of one shot, but have no clear of dbs characters being effective against supes in all areas of combat. Lets ice goku, he's now enveloped, what gift does he have to break free?! HEAT? You're siding with the weak end, goku will be looking at opaque darkness (he will witness himself quickly becoming blind!), because it will be hot. Superman can take him into space. What place will goku fly at if he can't see through darkness? You speak of Ki (being the dominant force, I'm just assuming since you speak of one shot!), but why use physical strength if their ki can discharge an explosion that level planets? You know they throw a LOT of ki blasts and the planet be fine. Your claim is strawman, it won't end in stagnant, and goku's stats aren't enshrouding in mystery, it's just your denial of defeat or letting supes go. The same scans of out of context display of Superman failing without telling or showing every detail from begining to end just means supes does lose to goku unless it's a plot device.
Also, the blob will make short work of them. His body can take their ki blasts, and it's curtains once they hit him physically! Plastic man would own them too.
