Kuuga could take out the forest with just one good Rider Kick

Ryuki would try to reason with it...then Knight would actually do what needs to be done...

Blade would sacrifice himself but totally save the day...

Hibikki...ummm...not sure, but I'm sure there would be a great drum beat to it.

Kabuto, man Clock Up would be interesting against the Inves. But Hyper form can do the Time Travel thing...kick a meteor into the main forest?

Den-O, again Time Travel, but with much better precision. Stop the situation before it got out of hand on the original world perhaps.

Kiva...they do have a dragon...BURN

Decade would just read this list lol
