Heroes of The Storm

[Psychospacecow]

This is Tychus's 2nd palette for his base skin.




This is his 3rd palette for that same skin.

Now, if you look at the higher up shoulder on his armor, you'll notice the second skin has a character from Overwatch in both of these skins.

The 2nd skin has Widowmaker.

The 3rd skin has Tracer.

As far as I can tell, the 1st palette is just a generic pin-up.
