Near Death Experience
As Dr. Eggman's empire began to crumble around him, he sought out the help of Dimitri, who was attached to a life support machine. By this point in time, Dimitri had changed his ideologies and had become more of a peaceful figure, and refused to aid Dr. Eggman. The enraged despot ripped Dimitri from the life support system, resulting in the ancient echidna needing his head to be preserved in a glass ball in order to survive.

By 3261, Dimitri was living in Lien-Da's house and often provided her with advice. When Lien-Da pointed out that she and Julie-Su weren't exactly on the best terms, he said "Now would be as good a time as any to mend some fences!". Dimitri later came to the aid of his great-great-great grandson Rutan, who was being scolded by his mother for being out past curfew with Salma. Dimitri explained young boys acted differently than young girls. An argument ensued in which Dimitri explained what had happened during his final encounter with Eggman, and that Lien-Da had acted in her own self-interests after he turned over control of the Dark Legion to her.
25 Years Later (Altered)
In the altered timeline during King Shadow's reign, Dimitri was still living with Lien-Da. When she explained how delighted she was to be Shadow's chief-enforcer and for imprisoning those who might overthrow him, Dimitri conveyed his anger at her actions, explaining he had not been ashamed of his bloodline since he had worked with Dr. Finitevus. Regardless, Lien-Da ignored her ancestor's opinion.
