Lightning

Lightning is a French bulldog Darkus Brawler that appears in Bakugan Battle Planet. His main Bakugan is Darkus Howlkor, with his secondary Bakugan being Artulean, and tertiary Bakugan being Phaedrus. Lightning speaks in Lightning Unleashed, with only the viewer and his Bakugan being able to understand what he is saying. Age: 18... in dog years. A French Bulldog, Lightning sports a collar that allows him to carry and launch his own Bakugan. All kids filming prank videos need a lookout and for the Heroes that lookout is Lightning. A stray found lingering in the back alley of Dan’s home, Lightning has become their unofficial mascot. A happy, dumpy, sleepy French Bulldog who often co-stars with Dan, Lightning isn't quite as fast as his name might suggest, but he's good for a "YAP" when trouble is coming. Lightning is the best dog in the world... and that was before the kids discovered that he could fight alongside them with Bakugan! That's right, a dog— one very special dog— has his own Bakugan and uses them in battle with his human friends! During downtime, Lightning is usually sleeping, eating or playing with the Bakugan roaming around Dan's house. But when trouble rears its head, Lightning snaps into warrior mode and can brawl with the best of them! Lightning is a dog, and yes, it's a little wacky that a dog is an active part of Dan's team, but as an animal he has a different relationship with Bakugan than any human could ever hope to have. His animal instincts can mean the difference between success and defeat for the whole team. And no, Lightning does NOT talk— at least not in any way humans can understand. But his loyalty to his friends, human and Bakugan alike, give his partners faith in his abilities... Even if he does occasionally bury a Bakugan in the back yard. Lightning is the canine member of the Awesome Ones. Despite being non-human, he is shown to be a capable brawler, giving instructions to his Bakugan through his barks. He has a small ball attached to his collar that allows him to easily carry and summon his Bakugan. (Source: Wiki)
