Alistar has been my main for a very long time now, and I have grown more and more fond of him as I play him more. He is sometimes referred to as the CC king, as he has many cc abilities and he is just overall a great champion. This is my first guide on MOBAFIRE so don't be too harsh. :)

Pros
-Doesn't die easy
-2 CC abilities
-AOE Heal
-Amazing ult
-Free Skin
-Best joke in the game

Cons
-Doesnt put out too much damage
-Not really focused

Passive: Trample: After casting a spell, walking over minions and champions damages them.
This is an OK passive, it is only useful when farming a huge creep wave.

Q: Pulverize: Alistar hits the ground, knocking nearby enemies up, dealing damage, and stunning them briefly.
I love this move when I'm fighting or running or chasing because it just destroys them.

W: Headbutt: Alistar charges to the enemy, does damage, and sends them back, stunning them briefly.
This move is good because you can send somebody into your teammates for them to kill them, or hit someone into a wall and stun them.

E: Triumphant roar: Alistar war cries, healing nearby teammates and minions.
This is an awesome move because it is an AOE heal. In a team fight, or pushing a tower, this can save you.

R: Unbreakable Will: Alistar shields himself, taking half damage from everything, removing debuffs, and gaining extra attack damage.
I freaking love this move, because it is cleanse, extra damage, and half damage from EVERYTHING. This makes turret diving a breeze, and you can deal some attack damage in the process.
