Tron hasn't been seen around much since
his loss to Erik in the Games. Most of this time has been spent in his sparse quarters, allowing his self-repair algorithms to work on his minor injuries (and largely attempting to ignore the not-so-minor ones).
He
lost. How could he lose in the Games? Granted, they weren't the same type of Games as back on the Grid, but still... this was what Tron was
best at... perhaps not his original design, but whether as Tron or Rinzler, he was undefeated. Until now.
Despite the self-deprecating thoughts running rampant through his processor, Tron can't remain sequestered in his room forever. Eventually, he emerges, and can be found either walking slowly through the Ingress Complex halls, or on the way to R1. One might notice that he is holding his right arm stiffly and close to his body, though no visible injury shows on the outside of his suit.
