He wasn't defeated by the water sword, Bisca shot him with the Jupiter canon and then Erza finished him of with the Yatagami armor
I forgot the end of the fight, but I maintain the absurdity of what I said: he shouldn't even have been hurt by it, but he was, because Mashima used Crocodile's weakness against his Crocodile knock-off, even if the powers being different actually makes his weakness being opposite.
Pretty much all the Spriggans took a team effort to take down
Ajeel- Erza with assist from Bisca
Dimaria- Wendy, Chelia with assist from Ultear
Wahl- Laxus with assist from thunder god tribe
August- Cana and Gildarts teamed up against
Irene- Wendy and Erza team up
Neinheart- Erza, Jellal and Kagura
Larcade- Sting, Kagura and Yukino
Bloodman vs Gajeel and Levy
Invel- Gray and Juvia, Juvia's apparent death giving Gray a rage boost
Only Spriggan that wasn't defeated by team effort was God Serena who got one shot by Acnologia and Brandish who became friends with Lucy and no longer had a reason to fight them
Yeah, they were team battles, but I fail to see how this changes how most (not all) were beaten by plot? I support how overpowered and superior they are, just not their handling.
Wahl in particular is the one I hold to a lower standard. The rest of them I just considered they were handled poorly and defeated by plot.
Wahl's hax was lightning immunity and he was still destroyed by Laxus, who only uses lightning magic. Wahl only had the upper hand until Laxus manipulated him to heal him and he stopped being on life support. Laxus didn't need any team effort to surpass him.
Then again, Laxus almost one shot Ajeel before this, so Laxus is just built different.
August deserves a special mention because he killed himself like an idiot. The teamup only managed to get him with one hit (that he should have been capable of dodging even if he can't copy an object's magic... precisely because he had other different copied spells on his arsenal. He had many options other than using Copy on the punch and he took it like a deer caught in the headlights).
Irene, to be fair, was beaten by fanservice, not by plot, and still ended up killing herself too rather than losing.
