Which race would you add to Heroes?

I'm writing upgrade ideas:
1: Boa - swallows rabbits and level 1 creatures...
2: Full Hat - it also attacks...
3: Macaque - demoralizes the enemy with an attack (reduces morale to the minimum)...
4: Copperfield... appears - is not vulnerable to magic...
5: Experienced magician, casts spells from a pre-prepared list of spells (configured in the castle...)...
6: Hunter - can kill a beast :)
7: There are many options here... for example, it can turn enemies into allies with laughter...

But seriously... let's suggest some normal factions...
