Nubis

Is it worth fighting everyone in the arena for because the last guy Is pretty much unbeatable

It’s worth having, but not worth rushing to get. Just wait until you level up some more.

It’s good but not that necessary. Get Arkwing first!

Last guy isn’t too bad with the right strategy, did it for my brother last night and he doesn’t have that many great arkadians.

Put a Stun arkadian (Storm Fox works well) Angelon or Halopard and Don Penguini at the back. Haste with Angelon/Halopard, then sacrifice. You’ll be left with a Don Penguini that can use Showdown quicker than the new arkadians that come in can make their first move.

I went through about 25 arkadians with just Don Penguini, and won.
