Does #17 and #18 have Ki?

[ahill]

According to the Herms translations, Vegeta said these Androids/Cyborgs don't give off any presence at all:

Chapter: 364 (DBZ 170), P10.1
Vegeta: “One of those guys with mysterious, absurdly large battle powers has vanished…But the other one remains…It’s not No.17 or the other androids. They don’t give off any presence at all…W-who the hell is it…!?”

But at the same time #17 donated his 'Genki' to the Genki-Dama:

#18 also used a technique which require chi at the tournament.

Trunks stated that he sensed #17's Ki in GT (100% canon), so yes.

They should have chi, but the text seems to state otherwise because they can't be sense all through the cell saga.

 

[Evil Vegeta]

They have normal human Chi, but Gero's cybernetics likely suppresses it.

 

[Let's Go Fearless!]

Of course they have.
