Ben 10: Alien Force, Season 3

Vilgax:
Where is he? Where is Ultimo?

Ultimos:
Right here Vilgax (flies at him) and rest assured you will pay dearly for your craven attack on my teammates. The Galactic Code of Conduct- (punches the Shield of Ziegel; Vilgax knees Ultimos, then slams him down)

Vilgax:
The Galactic Code of Conduct says that a conqueror's challenge is between the greatest warrior of the attacking race and the greatest warrior of the planet under attack. That's me...and you. Your teammates cheated, but that won't change the outcome.

Ultimos:
I am the most powerful hero on this planet. I'll perish before I let it fall into your hands.

Vilgax:
Yes....you will (blasts him with the Ruby Ray of Ulo)). I salute you. Few have withstood in assault from the Ruby Ray of Roleau.

Ultimos:
(groaning) I... can't... let you... win.
