Why didn't Goku just fetch the Dragon radar himself?

[Fizzer]

During the Boo arc, instead of sending Trunks to get the Dragon radar, then teleporting to Boo to distract him and buy time for Trunks, why didn't Goku just teleport to the Capsule Corporation and fetch the radar himself, avoiding all the messing about and having to go SSJ3 and burn up his remaining time on Earth?

Gokuu probably couldn't sense the ki of Blooma's parents. If he can't sense the ki, then he can't use Instantaneous movement.

Buu was heading to the city the radar was in anyway. For Goku to look for the radar would leave nothing to hold Buu off from destroying things (maybe something of value).

Gokuu probably couldn't sense the ki of Blooma's parents. If he can't sense the ki, then he can't use Instantaneous movement.

He doesn't need to, there is plenty of people living there, even if he can't teleport to the exact location, he can make it much quicker than Trunks.

Don't we remember what happened the last time Goku tried to find his way around West City all on his own?

Enlighten me, oh wise one.

[Kaboom]

He got lost. Things happened to him. Hijinks ensued.

[Son Edo]

Cheers! Kaboom.

[Kid Buu]

I think he wanted to test out how strong Buu was, as well.

...And use SSj3 for no reason, even after he'd said just moments before that he didn't want to have to go that far. It's simply a plot device to introduce SSj3. I wouldn't put too much thought into the "whys".

[Piccolo Daimao]

Out-of-universe: everyone in the Boo arc were using the plot device of the Idiot Ball, so it was nothing more than an excuse for Toriyama to show off Super Saiyan 3.

In-universe: Gokuu may’ve figured that Trunks would be able to get to the Dragon Radar faster because he knew Blooma’s parents better than him (flawed logic, but Gokuu’s stupid and/or he may not have been thinking clearly under stress), and/or he wanted to stop Boo destroying the inhabitants of West City at all…well, most costs. Also, he wanted to test out Boo’s strength, because he’s a Saiyan, but maybe because he wanted to prove to himself that he wasn’t enough to defeat Boo after all and their only hope was in the boys.

Goku didn't know where exactly the Dragon Radar was. He could've teleported Trunks, though.

[Jackal puFF]

Simple answer is Goku wanted to have fun with Buu. It's exactly the same reason why he didn't kill him too. He wanted the others to have fun with Buu.. You know dying and stuff.

[matt0044]

I guess he wanted to keep West City as safe as possible while Trunks got the radar. I mean, I guess time was kinda the essence then.

[DoomieDoomie911]

I think that Goku just didn't have time to think, and went ahead and sent Trunks to get the radar. Also he wanted to have some time with Boo. Basically Toriyama just wanted a way to introduce Super Saiyan 3.

[caejones]

This is starting to make it sound like Goku is getting addicted to experiencing death, .
And he wants to get everyone else to try some, but he still has moral objections to killing people for the lulz.
But he's more addicted to fighting, of course.
... o.o I think I've just thought of the worst fanfic ever (barring MyImmortal).

But, yeah, the out-of-universe explanation of introducing SSJ3 seems to be the most logical explanation. I'm having trouble thinking of situations where Goku can come up with great split-second strategy under stress (other than fighting tactics, which ninjaing the dragon radar is not).

[Monkey D Goku]

Goku probably did it that way so he could take a look at the warrior who killed his rival and "supposedly" killed his son.
