Comics, mangas, community!

At first, I thought it was far-fetched because they don't have a container, but as some lad said in the previous page, he just needs to throw him off the ring. Thus, he wins and is clearly taking a senzu (exactly as did Roshi).

Good job, Chewys, you had a very well done idea. Regardless of how strong Haarp is, he can't know the mafuuba, as he never witnessed it.

And he's going, going, aaaaannnd he's gone. Ladies and Gentlemen it's a home run!

Good on Tien, learning the Mafuba after just seeing it once? That would make Fat Buu proud.

Go Tien! Go Tien! Hopefully he has enough energy to guide Haarp out of the ring, or even further out of sight, like he did with Banjo. Gohan still has some Senzus, so Tien likely shouldn't die.

@Jason Phoenix

Yes, many fighters in Dragon Ball have shown to have the ability of learning moves after seeing them once!

For example:
Tien with the Kamehameha and the Mafuba

Goku with the Kamehameha, King Chappa's 8-Armed Fist, Solar Flare, Kienzan, etc

Chiaotzu did a much lesser version of this by blowing himself up, similar to how the Saibaman blew up Yamcha.

Vegeta also learned the Kienzan after seeing it a few times from Krillin, as well as the Ki Sensing ability when he sensed the first Spirit Bomb.

Do it Tien! Throw him off. ^^

Amazing artskill.
