Cerambus

Cerambus is a Beast Wyvern introduced in Monster Hunter V. It's also one of the game's 3 flagship monsters.

Physiology
Cerambus resembles a ceratopian dinosaur, like Triceratops or Torosaurus. It has blue scales covering its skin, with navy blue scutes on its back. Two massive, curved horns sit atop its brow, along with a smaller horn on the nose. It has a large frill on the back of the head, which it can use to absorb sunlight to convert into electricity. It has a relatively short tail. However, this tail has a mace-like club at the tip, meaning it can be used as a secondary weapon.

Basic Attacks
Stompquake: Cerambus rears up and stomps hunters with its front feet. Causes Quake if close.

Charged Stompquake: Cerambus rears up like normally, but electricity forms around its hind legs. When it comes down, it has a wider area of effect than normal. Causes Quake and Thunderblight.

Horn Swipe: A simple swipe with its horns. This can be repeated.

Head Thrash: Cerambus wildly waves its head around, dealing damage to anyone it hits.

Tail Slap: Cerambus waves its tail around, damaging hunters behind it.

Bull Charge: Cerambus lowers its head and charges like a bull! It can change direction once during this attack.

Uppercut: Similar to Gammoth, Cerambus drags its head along the ground, then jerks its head skyward to impale enemies on its horns. Causes Stun.

Stormlance: Cerambus engulfs one of its horns in electricity, then jabs it straight forward. If this attack hits, it will cause Thunderblight. Has a large windup time.

Electric Wrath: When entering Rage Mode, a lightning bolt will strike Cerambus's horns. This will make its horns charge up with electricity. All horn attacks will now cause Thunderblight, and Stormlance's windup time is lowered greatly.

High Rank Onwards
 

Flail Kick: Cerambus quickly kicks with its back legs to prevent hunters from attacking its weaker rear end.

Turnabout: Cerambus spins around 180 degrees, turning to face hunters attacking its rear end.

 Lightning Arrow: It shoots an arrow-shaped electric projectile from its nose horn. This attack causes Thunderblight.

Electric Trident: Cerambus engulfs all three of its horns in electricity, and then charges. This is its most powerful attack, and inflicts Thunderblight.

Delta Thunder: Cerambus summons blue lightning bolts to fall from the sky in a triangular pattern. Causes Thunderblight.

Behavior
Cerambus is surprisingly territorial. If it feels it or its young are in any sort of danger, it will chase and trample attackers until they are either gone or dead.
