- Black Widow: Tony.
- Tony Stark Hulked Form: Natasha? I told you to...
- Black Widow: Stop. Clearly time is the enemy. What's happening and how do I help?
- Tony Stark Hulked Form: It's a virus infused with gamma energy. Once in the blood stream, it simlates the effects of Hulk-ish-ness. Hulk-osity?
- Tony Stark Hulked Form: Stark smash!
- Captain America Hulked Form: Avengers SMASH!
- This episode shows that even though Hulk acts immature and stubborn around humans, he doesn't around other Hulks. A similar yet less uptight behaviour to his character in Hulk and the Agents of S.M.A.S.H.
- Hulked out Heroes is the only episode with the Blood Brothers.
The episode reveals that Thor is not completely immune to Earth diseases and radiation poison, as he too gets mutated by the gamma radiation, along with the other Avengers.
