Dean/Enj
Dean knew what Enjolar had said, and knew what he was talking about as they burst loudly.
Dean would not lie and say the cannons did not hurt him, but this kind of pain was still nothing to a Totem Barbarian such as himself. A tentacle swipe from a Kraken a claw strike from a Black Dragon, or a chomp from a Tarrasque? Those hurt. But, Dean was more than happy to take the brunt of the assault for both in front and behind him. While dumb, he had fantastic battle awareness.
Enjolras was correct to back up, though Dean's tail would have avoided him, the lightning on the spine of it may not have. The charging sound grew louder as the blue lightning began to move up the spines of his back, through the cloud of dust only this was illuminated. Even the army not fifteen feet in front of them could see it happening.
Finally, the charging stopped as it reached the top of Dean's neck as he stood up straight. In what seemed like an eternity, everyone on both sides waited on bated breath, waiting for what would happen next.
"DDDDEEEEEAAAAAAANNNNNN!!!" The Dragonborn would roar out as he leaned forward firing a singular straight line of lightning from his mouth. The sound of the crackling was nearly louder than the cannon fire. It hit the first few rows of the men in the army in front of them, basically frying them. Some of the bolt would chain off to others, frying or injuring them greatly. After a second of two of this, it died down. With a flap of his wings, the dust cleared, and the french stood could be seen, 'shocked' and terrified by what they just witnessed.
