Sombra was very much a gentle giant before he was corrupted by the Malice (though still was obv pissed when he was mocked or hit), he would rather not continue the confrontation. He also sang with the birds that would flutter by, and would even make up his own songs- like this one called "¿Alguna vez has visto?" or "Have you Ever Seen?" which was some sappy love song that was so sweet it would rot your teeth.

Sombra is bilingual. He can speak both English and Spanish thanks to his adopted mother Chestnut Falls, whose native language was Spanish- as mentioned "here:":https://www.deviantart.com/gingygin/art/Plead-880168166
