The androids, piccolo and the humans

[Mazingerdestro]

No need for a power up IF the tournament goes beyond fights.
I have to say that as individuals everyone except Goku and Vegeta are weak.
However, what they lack in power they have in skill.
17+18 infinite power
Krillin's kienzan
Tien's kikoho
Master Roshi's mafuba
Piccolo's quick thinking and analytical skills
Gohan's.....gohan...ness

First, Krillin's Kienzan being useful is based if you believed that it can cut through anything regardless of power, which have never been proven. On this forum, the Kienzan has the unlimited power fallacy applied to it.

Tien's Kikoho could only pushed Semi-Perfect Cell without doing any damaged to him. So that is limited even if it allows Tien to hit people outside his power range.

The Evil Containment Wave is not something Roshi can just do. You need a seal and a place to trap the opponent. Even then, it will kill Roshi since he's so much weaker than anyone else he uses it on.

All the attacks that I mentioned aren't meant to kill but to provide a strategical advantage. Tien's kikoho can push someone to Krillin's or Piccolo's range, so they can damage him.
Also Piccolo and Krillin have demonstrated the ability to fight as a team, something that the android siblings can also do.
Tien and Master Roshi can combine their mafuba knowledge to avoid dying (even if I think that they have enough ki to use it now) and push someone off the ring etc.

Gohan can.....still thinking it, give me a min....

That is assuming that Tien's opponent is weak enough to be push. The Kikoho didn't pushed Super Buu after he absorbed Gotenks for example. Krillin's attacks damaging anyone is questionable for the reasons I named. Piccolo and Krillin fought in a team, and got wreck by Nappa, so teamwork can only go so far if your opponent is laughably stronger. The same with the androids.

Tien and Master Roshi would still need to set up the Evil Containment Wave. It isn't something that can be done on the fly. And they will die if their opponent is much stronger than them. The reason why Future Trunks did drop dead was because Future Zamasu was within his power range and may have been a little weaker.

Kikoho did allow him to blast away an attack from a at least 1000 times stronger.
Also I don't get the kienzan hate since Goku was able to cut buutenks who again was way stronger than him and Goku used it in the normal form.
The mafuba has no clear instruction but I thought that the reason you die is that you pay high ki cost to activate it. Saiyans can use it. Additional ki drain is applied if the opponent has the ability to somehow resist it. Zamasu didn't resist and Trunks was already too weak from fighting black in SsjSsjGod.
In Piccolo and Krillin vs Nappa case, both were at best like 1500 when Nappa was at least twice stronger if not more.
Again you are referring to battles, I am referring to strategic advantage for example in a tournament like in fairy tail. You have battle but you also have trials

You're ignoring that blast was aimed at Denda, who wasn't thousands of times stronger than Tien. Buu was also pierced by bullets and Dabura's spear, so the Kienzan cutting Buu isn't impressive.

The Evil Containment Wave kills based on how much strain you put on yourself. If your opponent is vastly stronger, the more strain it puts on the user. Trunks was even or stronger to Future Zamasu, which is why he didn't die.

Who says the tournament would be like Fairy Tails Grand Master Games?

Well we haven't really seen anything NOT get cut by a Kienzan that hits home in canon yet, and the attack was deemed dangerous enough by Nappa and Frieza that it momentarily caused Krillin to become a threat to them despite their overwhelming power advantage. Hell; it's the only attack that does any significant damage to Frieza at any point which speaks wonders about it's potential.

That's most likely where the Kienzan praise comes from.

There's also the chance that cutting Freeza's tail is like cutting a Saiyan's tail though - like how Yajirobe cut Vegeta's tail even though he obviously wouldn't be able to cut through Oozaru Vegeta himself.
