Captain Cadaver said:Trunks fought evenly with a #18 out to win rather than playing around, whereas Piccolo wasn't even as strong as the Vegeta that could compete with a casual #18. Absolute stomp in Trunks' favour.
Kenshi said:Trunks stomps. I think #18 could've easily raised her battle power to the level she used against Vegeta if she felt like stomping Mighty Mask and Trunks was as weak as this version of Piccolo.
Her motivations in both fights were entirely different. Against Vegeta, she just wanted to mess around. Against Mighty Mask, she wanted to end it quick and get the money. Enjoying herself was nowhere near as important when considering she passed on the risk of tracking down Babidi in favour of getting money and the rules of the Budokai would make her not act carelessly. As you said, the fight with Vegeta was a deathmatch from Vegeta's perspective, whereas #17 and #18 treat the whole situation as a game.GreatSaiyaman123 said:But even on a fight to the death (At least from Vegeta's perspective) 18 didn't bother going all out from the start until he asked her to. Is it possible she showcased more than one level of power during their fight?
