Which Duel Mode character was your favorite and why? I always liked the Piranha Plant because he had the highest attack power (3). The Whomp was always the dud partner that you wished you never had. He had an attack of 0 and defense of 4. I only wanted him when I had two partners at a time.
It would be Boo, since he could counter-attack. And with an attack power of 2, it's not so bad. Goomba is also a worthy partner to have, but the downside is that it has a Stamina of 1.
Piranha Plant would be my favorite partner. He really did prove to be very useful as a partner to me. His attack power really did come in handy too. Though, I rarely ever got him as a partner...(that is, unless of course you always pick Waluigi)
My favorites are Toad, Koopa Kid, Whomp, and that's it. Toad prevents coin loss, which means you have money for partner salary, Koopa Kid, transforms into Bowser if the nothings in the way, and deals a lot of damage. and Whomp can take a lot of prevent a lot of damage. Another good combo was Snitfit and Mr. Blizzard.
My favorite was Chain Chomp even though he costs a ton he attacks the whole opponents team. My second would be Bob-omb because he just blows him self up right on the opponents head ignoring the partners guarding them.
