Well damaging his shirt is better than no damage at all though by facial expressions Tao does indeed less affected and one can argue the Saiyan armor which is designed for battle would have better protection than a regular shirt
King Piccolo wasn't going to nuke the planet in one-shot. He was going to destroy a major city every year until the planet would ultimately be destroyed.
Because Piano is shown shitting himself when Goku starts beating up Daimao implying that he didn't know Daimao had another power up beyond his young form which he knows is already so much stronger than he was pre wish.
Daimao arc power jumps are really nutty lol.
You think Roshi wouldn't try a Max Power KHH if it could kill Piccolo? Mafuba was equally risky, if not more so and he didn't even consider using his max power form. Daimao didn't even try to dodge when Goku hit him with his KHH so it's unlikely he would have feared Roshi's either.
Vegeta wasn't near death after getting beat vs Recoome and still got a zenkai. In fact the largest by far zenksi he's ever got at that.
Goku also was confirmed to had gotten stronger after muscle tower. He did no training in between so that is the only possible explanation.
During Tien vs Jackie Chun's match. Tien uses all three of his eyes to see through Chun's afterimages.
That is the only time I remember Tien using his third eye beyond an aesthetic.
Yajirobe can be weaker than Goku while still stronger than Tien. He atleast has better durability. He might lose if he doesn't use his sword due to Tien's variety of techniques though.
The Super KHH is portrayed to be stronger. It's the strongest ki attack in part 1 db. Piccolo surviving it was just plot like how a battle worn Vegeta was able to survive a half powered Genkidama that could have defeated him in his Oozaru form.
