Benjamin Kirby "Future Ben" Tennyson is a rogue possible future of Super Ben's who appears in Back in Action: Alien Universe.


This section is incomplete.


He kept his secret identity for quite some time, even while working to aid the Null Void Incarcecon escapees. Even after knowing he was not Super Ben's future, he continued to manipulate him for unknown reasons.

He is aware that Elena Validus has a crush on him, even at his current age. He plots with Elena (who also works with Albedo, Scarogus, and Tersce Tenebrosi) to keep the secret that she has Magister Frikton in a jail cell on the Commander's ship from his present self, but his motives are not clear.

Back in Action: Alien Universe[]

This section is incomplete.
  • In The Sea's the Limit, he appeared using an array of aliens, including Atomhammer, to stop Overlord Zyzz and Murmadan by sending them to the Vigilanuum home world of Chronospect, a time-defiant jail which exists beyond every timeline, as well as in every timeline, as one. He also begins the Plumber initiation process for a Gourmand named Gooron.
  • In Happily Never Happened, he is mentioned several times by Ilario and Kitty Rhymes, and later appears during Endgame as Thep Khufan Commander Tersce Tenebrosi watches over Chronospect.
  • In Revelation, he appears to thwart Vilgax, Malevolence, Slix Beta's NVI escape efforts, letting only Cyanne Albedo go, to ensure the events of Future Ben's past happen in Ben's present.
  • In Ledger Recon, he breaks the news to Super Ben about Gwen's and Chelsey's deaths.
  • In Welcome to Chronospect, he joins Super Ben in Chronospect in an attempt to stop the Thep Khufan Commander before he attains the Chronogen crystal—the last piece of the Tritadagen. The attempt ends with him being murdered by the Commander so as to reattain the Chronogen and make it back to the Tertiary Wing safely. When he is killed, the Commander takes his Omnitrix and kicks him off the edge of a rock on the planet, dropping him into an abyss.
  • In Dusk's Endgame, Future Ben changed bodies after the NVI Baron body he had been hiding in had been caught by the Warden doing suspicious acts.
  • In Malevolence, he assisted Scarogus, Malevolence, and Vilgax when their escape effort almost failed by using Upgrade to power on their ship's computers after Malevolence mistakenly Impulsed it.
  • In Never Set in Stone, he manipulates Ben into killing Scarogus, Malevolence, and Vilgax, though he refuses, and he himself kills Ore and nearly Ilario. Super Ben forces him to return to his time after nearly killing him and engaging Future Ben's SDM.
