There is 0 consistency in the game on wether the bear is considered a creep or a hero unit. Here's a few examples on top of my head:
Creep interactions:
- Doesn't make lane creep aggro enemy when targeted
- Can be targetted by Axe ulti, but doesn't give stacks to Axe
- Can't have illusions
- Can't carry Aegis
- Can't pop smoke
- Can't get Moonlight Shadowed
- Deals lower damage to Supernova, Tombstone, Wards etc.
Hero interactions
- It itself takes lane creep aggro when focusing a hero
- Can be targetted AND give ulti stacks to Reaper's Scythe
It's like they've chosen the worse one every single time it's relevant.
