I've finished the game but was wondering, if I use all 5 party members in the final battle (with their respective quick time events) do I get a different ending?

I've finished 2 play throughs and the ending is the same.

Well there's one alternate ending if you're walking away from the snuke earlier, but that's it.

Ok. But has anyone tried to exhaust all of the last boss's abilities?

I don't think it matters, just like the Cartman vs. Kyle choice.

There are special abilities for each buddy, I presume if you exhaust all your buddys you will be left alone.

Though, it would take awhile to exhaust all your buddys help. Considering I beat him/her with a makeover outfit on.

No matter which buddies you use in the final battle, you get the same ending.
