How to Watch How to Download

An explosive combination of deep-space diplomacy and raw, unadulterated anger collides in Ben 10: Alien Force Season 3, Episode 13, "Con of Rath." The team sets off on a vital escort mission that descends into absolute hilarity due to a major technical malfunction.

When an advanced alien ambassador begs the legendary Plumber trio to securely deliver a fragile piece of political peace offering across the cosmos, Ben confidently steps up. However, an unexpected glitch in the Omnitrix locks him into a brand-new, incredibly aggressive tiger-like alien form, making an already delicate intergalactic negotiation nearly impossible to handle peacefully.

“Let me tell you something, intergalactic warlords! Rath will jump down your throats and turn your lungs into a set of bagpipes!”

Episode Summary

The episode kicks off with Ambassador Zaw-Veenull of the planet Lewoda approaching Ben, Gwen, and Kevin with a highly sensitive request. He needs them to transport the young Appoplexian prince, Tiffin, to the fearsome warlord Jarrett of Pantophage as a peaceful treaty offering to prevent an all-out planetary war. The main catch: Tiffin is highly sensitive, and any severe agitation could completely ruin the diplomatic arrangement.

The mission goes immediately off the rails when Ben tries to use the Omnitrix during a minor space pirate ambush. Instead of a standard transformation, the watch glitches, locking Ben into a highly aggressive, orange-and-white feline brawler named Rath. Due to Appoplexian biology, Rath possesses an incredibly loud voice, absolute fearlessness, and a severe lack of basic impulse control. He is constantly angry, picking fights with inanimate objects, his own teammates, and anyone in his line of sight.

Despite Gwen and Kevin’s desperate attempts to keep the situation calm, Rath’s explosive outbursts terrified the young Tiffin. Things escalate further when they finally arrive at the Pantophage homeworld. Jarrett, a massive, gluttonous alien beast, decides to break the treaty by swallowing the tiny Tiffin alive. Infuriated by this act of extreme disrespect, Rath dives directly into Jarrett's massive mouth, aggressively fights his way through the warlord's digestive throat, and forcefully yanks the young prince back out to safety, forcing Jarrett into a terrified submission.

Themes & Character Development

The Burden of Temperament: Rath represents the ultimate test of Ben's mental fortitude. While other transformations allow Ben to maintain his logical mind, Appoplexian biology completely hijacks his emotional state, forcing him to fight his own internal rage to achieve a heroic outcome.
Unintentional Protective Instincts: Despite his constant shouting matches and aggressive behavior toward Gwen and Kevin, Rath's subconscious heroic core is spotlighted by how fiercely and ruthlessly he protects the defenseless Tiffin from harm.
The Comedy of Contrast: The narrative brilliantly juxtaposes the high-stakes, formal protocol of an intergalactic peace treaty against the absurd, wrestling-promo style rants of a massive space tiger, offering an unforgettable comedic experience.
