This is actually very tough for me I like the Reel, Crystal Snake, and the Fireworm they all have such cool lore. I think my favorite is the Fireworm because I like how it lives in Lava and was able to fight Luke in Legends. Second place for me would be the Crystal Snake as It makes me laugh how he basically killed orvak lol. 3rd place for me is the Reel, I love its color scheme it reminds me of the black momba from our world but about 50x bigger. Oh and Here is some cool art of Luke Fighting the Fireworm.
