The guiding angel, Yoshi.
Yoshi is a character who has abilities to help Mario reach his destiny and in turn, you go up higher in the level of the game. Memes talk about the same relationship between Yoshi and Mario but depicting it through the Marvel characters, funny memes.
Red skull was so doomed that he had no other place to go except the cold, dark world and to protect the soul stone. When Thanos came to take the soul stone, Red skull, helped him take it. Red skull guided him, that was his only purpose in life, just like Yoshi, he was meant to help Mario.
