There are several different types of boar minions in Hearthstone.
Boars may be collectible or uncollectible, but all of them are Beast minions. All boars except 
Duskboar, 
Helboar and the Boar summoned by 
Razorfen Hunter have Charge. With the release of Ashes of Outland, Helboar is the first boar to have a different effect.

Lore
This section uses content from Wowpedia.Boars (aka wild boars) are a common, usually furry, cloven-hoofed, four-legged beast that is the wild ancestor of the domesticated pig. Most boars are neutral when approached and are generally omnivorous. They start at around large dog-sized and get larger from there. Some boars are minions of the quilboars and are revered within quilboar culture, and particularly large and tenacious ones are seen as a favor from Agamaggan. Boar meat is the staple diet of the orcs.
