#4 Mustafa Ali
When it comes to heart, there is nobody on SmackDown Live that has a bigger heart than Mustafa Ali. Ali had debuted in the WWE as part of the 205 Live rosters, and despite the fact that he didn't win the Cruiserweight Championship, he did indeed make a name for himself with his tremendous abilities to tell a story in the ring.
Ali is the young underdog that SmackDown has desperately needed, which is why SmackDown is the perfect brand for him. When Ali made his debut on the main roster, we saw him immediately confront Daniel Bryan for his recent actions towards AJ Styles and other superstars. He stepped up to Bryan like no other superstar did, and despite the fact that he lost to Bryan in his debut, he received a round of applause from many superstars in the back.

The reason why Ali would make a great opponent for Orton is due to the fact that both men are the complete opposites at the moment. Orton is currently performing as the cold heel who just wants to destroy anybody in his path, whereas Ali is the resilient underdog who is simply trying to make it in the WWE.
Let's not forget that Ali also holds a win over Bryan, as he pinned the WWE Champion in a Tag Team match whilst teaming up with AJ Styles. Despite the fact that Ali failed to gain a shot at the WWE Championship for the Royal Rumble 2019 event, he is still a very credible opponent to take on Orton at WrestleMania 35.
