AppearancesTRON 2.0: Killer App (Game Boy Advance)

Securo is a security program in TRON 2.0: Killer App (Game Boy Advance). He is the final boss of Tron's storyline in the game.


Securo is a security program with a large, abnormal appearance unlike most other programs. He floated in the air when first discovered, and would unfold as a large scorpion when deployed on the ground. He speaks in a very automatic manner, saying some words one syllable at a time.


Securo spins and launches grenades from above while in his first form. In his second form, he marches and quickly fires grenades from his tail.


TRON Wiki - TRON Killer App Securo Nodes (All)

The Nodes from Left to Right: "No Rings", "One Ring" and "Three Rings".

Securo appears in an arena which has a small yellow pyramid at each of its four corners, and is surrounded by four nodes at his left and right, each on its own small platform. Thrown discs bounce off the pyramids, allowing the player to ricochet for a single or double hit. Each node has three layers of shielding; each layer can be broken by a disc strike or by the player jumping to the platform and performing a dangerous stomp-attack.

In his first form, Securo slowly floats in a small circle. He cannot be hit while in the air. Securo does a quick spin before launching a grenade directly at the player every second or two. These grenades cannot be deflected, only dodged by the player.

In his second form, Securo lands and fires grenades from his tail at a much faster rate; however, the grenades can now be deflected. He chases the player until struck enough times to stop and derezz.
