Alright, our first character up is going to be Iron Man, considering Tony Stark here is often seen as the sort of patriarch character of the MCU. Even though the 2008 Hulk film was technically first. Regardless, there will be eight interactions per character. Why eight? Well my Injustice series was 10, and Overwatch is 6, so I'm going in the middle ground here. So, let's get started. Spyro's in the ring, let's do this!
Iron Man: Don't you have a treasure hoard to guard?
Spyro: Not funny, Tony.
Iron Man: I was going to offer you a security position.
Spyro: What sort of mechanical monstrosity are you?
Iron Man: Now that's just harsh, Spyro.
Spyro: How do you know who I am?!
Iron Man: I've faced a lot of crazy things, but nothing like you.
Spyro: I can say the same with certainty.
Iron Man: This should be interesting.
Spyro: You said you needed my help, Tony. What for?
Iron Man: Testing whether your mana can act as a core for the Arc Reactor.
Spyro: It's certainly possible, I think.
Iron Man: You remind me of a friend of mine.
Spyro: Let me guess, Cap?
Iron Man: Spot on, but without the beard.
Spyro: So you built your first suit in a cave with shrapnel in your heart?
Iron Man: The Arc Reactor tech saved me. The suit got me out of there.
Spyro: But the mind behind it was calm enough to work both.
Iron Man: You ready for a brawl?
Spyro: You reek of whiskey. Have you been drinking again?
Iron Man: Please. I took down the Hulk while hungover.
Spyro: So you're the Iron Man.
Iron Man: And you must be this Spyro I've heard so much about.
Spyro: Let's hope that armor's heat resistant.
