Ben Fotino

Ben Fotino is the strongest member of the Starco Avengers and the alternate personality of Alex Hirsch. He is the stand-in for the Hulk in the EBA Edited Universe.

In the EBAEU
Ben is first introduced in the War for Starco. He is with Adam McArthur and Tom Lucitor when Daron Nefcy attacks their transport to take the  Dimensional Scissors from them. After a cue from Tom, Ben attacks Daron and actually has the upper hand at the beginning of the fight, but Daron soon overpowers him and knocks him unconscious.

When he wakes up, Lekmet has used the last of his power to send the green giant back to Earth to warn the Starco Avengers of Daron's imminent arrival. After passing the message to Star Butterfly and Omnitraxus Prime, Ben morphs back into Alex. Later when the Children of Daron attack the heroes to try and claim Father Time's Wheel, Alex tried to turn back into Ben, but Ben refused to be just Alex's lackey.

Currently, Ben is still a part of Alex, but the two are still at odds. His fate will be decided in Daron's Endgame.

In SvtFoE
In the show Star vs the Forces of Evil, Ben is voiced by Alex Hirsch and has only appeared once. This was in the episode Booth Buddies. In that episode, he was the technician whose job was to repair the photo booth after Star and Marco jammed it with the sheer number of photos they took. After clearing the jam, however, he realized that the two needed to work out their feelings for each other and locked the door until the two of them kissed for the first time. After retreating back into the booth at the end of the episode, he has not been seen again and it is not known if he will return.
