Skylanders Giants - What Skylander Do I Need to Defeat Frightbeard?

I'm trying to defeat him, but there's something wrong.

I have Cynder and Flashwing active in my team, but it says in the Pause Menu that it's an Elemental Match, meaning that Fire is the key, but I don't have a Fire element Skylander. I only have Undead, Life, Earth, Magic, and Air elementals. Do I need to get a Fire elemental to defeat him?

If so, what Skylander should I get (must be a Fire elemental) for the battle?

So from my understanding, are you saying that you think you need one Skylander of each element to beat him? 'Cause you technically don't need several Skylanders to beat the entire game, so it shouldn't be a problem.

But if you want to get a fire Skylander, I'd reccomend Hot Dog. He can shoot fireballs and firewalls which are pretty powerful, and he can do Comet Slam which is a really cool attack. Plus there's plenty of other cool upgrades. He's pretty adoreable as well so that's a bonus.

I would prefer Hot Head, because he's a Fire Skylander, too!

Then it's settled. I'll try to obtain Hot Dog when I can.

When I beat him, I used hot head & tree rex.
