The campaign I'm running features orcs, hobgoblins, and bugbears as prominent enemies, but the players are getting bored with the same old monsters, so I was wondering if anyone has heard of orc, hobgoblin, or bugbear variants. Could be homebrewed, from a blog, etc. Thanks in advance!

Step 1: pick any humanoid monster

Step 2: Pick which race to convert it to - soldiery, high AC monsters should be hobgoblins, brutes/sneaks should be bugbears, etc.

Step 3: Add the Martial/Arcane Advantage feature for a hobgoblin, Agressive for an orc, Brute for bugbear.

Step 4: Remove any features or attacks that wouldn't fit, or figure out how to reflavor them to work.

That's about it. That should work for most of the humanoids in the game. Other types too, although that may need more adjustment of stuff like stats and resistances.

Well... there are a quite a few orc and hobgoblin variants that are official, if you look for them. I count a total of 10 orcs and 5 hobgoblins. For orcs, there are...

The CR 1/2 Orc.
The CR 1/2 Orc Nurtured One of Yurtrus.
The CR 2 Orog.
The CR 2 Orc Claw of Luthic.
The CR 2 Orc Hand of Yurtrus.
The CR 2 Orc Eye of Gruumsh.
The CR 4 Orc War Chief.
The CR 4 Orc Blade of Ilneval.
And the CR 5 Tanarukk.

For hobgoblins, there are...

The CR 1/2 Hobgoblin.
The CR 2 Hobgoblin Iron Shadow.
The CR 3 Hobgoblin Captain.
The CR 4 Hobgoblin Devastator.
And the CR 6 Hobgoblin Warlord.

And for bugbears, there are simply...

The CR 1 Bugbear.
And the CR 3 Bugbear Chief.

All of the above monsters that aren't in the Monster Manual are in Volo's Guide to Monsters.

Orogs are half ogre half orc right? And I like the Tanarukk. One of my friends used them in her campaign.

 Actually, they haven't. Must remember to use one in a session soon.
